PanelDue (touch-screen controller for Ormerod) availability I am pleased to announce that manufacture of my touch-screen controller for the Ormerod has commenced. For those of you who have not been following the thread about it, the fitting instructions and some more pictures of it are at https://miscsolutions.wordpress.com/paneldue/. [img]https://dl.dropboxusercontent.com/u/19369680/2015-01-08%2017.15.18.jpg[/img] [img]https://dl.dropboxusercontent.com/u/19369680/2014-12-05%2023.52.54-1.jpg[/img] If you want one of these for your Ormerod, you have two options: 1. Buy the board + connectors from me. Buy the display yourself, and make up the 4-way connector cable yourself. You will need some wire and a crimping tool. If there is demand, I might be persuaded to supply ready-made cables for an extra charge. I do not intend to offer displays. 2. Buy a complete kit (board + display + cable) from Think3DPrint3D. T3P3 have not yet announced prices and availability, but expect an announcement from them soon. I expect to be shipping these boards from about 21 January, so I am accepting orders now. The price of the board + connectors is GBP39.50 + shiping + VAT when applicable. This comes to the following totals: [code] UK 49.92 EU VAT paid 58.13 Europe no VAT 48.44 Rest of world 49.51 [/code] The "Europe no VAT" price is for countries in Europe but outside the EU, and also for EU VAT-registered (and also VIES-registered in the case of Italy) entities. To order, please send me a PM with the following information: 1. What you want to order 2. Which country you want it delivered to. 3. How much you expect to pay. 4. Your Paypal email address. 5. If you are EU VAT-registered and claiming the "EU no VAT price", your VAT registration number. I will send you a Paypal payment request when I have a firm delivery date for the boards. Please note: * The board works with recent versions of my firmware fork (e.g. 0.78za-dc42). zpl's fork should also support it, but this has not been tested yet. The board will not work with the RepRapPro 0.78c release, which lacks support for the serial port that the PanelDue connects to. * The board has to be connected to 4 expansion pins of the expansion connector on the Duet, or the expansion connector on the DueX4. So you need enough depth in your enclosure to make these connections. * Displays that appear to be compatible include: 1. [imall.iteadstudio.com] (tested and working) 2. [www.ebay.co.uk] (earlier version of board tested and working) 3. [www.ebay.co.uk] (not tested) 4. [www.ebay.co.uk] (not tested) 5. [www.sainsmart.com] (not tested) I have not tested numbers 3, 4 and 5 but to me they look identical to #2. There are many similar-looking boards available on eBay. The important features are 4.3 inch 480x272 pixels, on-board SSD1963 display controller and XPT2046 or compatible touch controller, and 40-pin connector supporting 16-bit parallel interface with the correct pinout. Note that boards shipped from China typically take 2 to 3 weeks to arrive. Some of these boards are available locally in some countries, but generally at much higher prices that direct from China. The board also works with the Itead 3.2" widescreen display, however I may withdraw support for this board in future firmware released. The board also works with the Itead 5" 800x480 display, but the firmware currently treats it the same as the 480x272, so it doesn't use all of the screen area. * Power consumption of the board+display is nearly 300mA @ 5V. When used on an Ormerod 2, this will increase the power dissipation in the linear voltage regulator by around 2W. It is possible that additional cooling will be needed (I don't have an Ormerod 2 to test with). * The firmware is rather basic at present. I intend to add some more functions before shipment, but expect the firmware to change rapidly for several weeks. You can update the firmware using bossac and a USB cable, exactly as you do for the Duet. * Still needed is a design for a printable enclosure. A couple of Ormerod owners did provisional designs, but they need to be completed. https://reprap.org/forum/read.php?340,452641,452641#msg-452641 Mon, 17 Aug 2026 12:49:22 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?340,452641,745167#msg-745167 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,745167#msg-745167 dc42 Ormerod Sat, 04 Feb 2017 02:29:39 -0500 https://reprap.org/forum/read.php?340,452641,745105#msg-745105 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,745105#msg-745105 Or do you use a completely different method?

Any ideas on going about this?

EDIT:
The way i was thinking of going about this was to render the .bmp at the position, and check if the touch input is withing the pixels of that image and register it as a buttonpress.
I'm not sure though if this is a viable way to do this, or if it would interfere with popup windows]]> Napalm1432 Ormerod Wed, 01 Feb 2017 06:44:25 -0500 https://reprap.org/forum/read.php?340,452641,714131#msg-714131 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,714131#msg-714131

Dear David,
Great work as usual! Do you still sell the 4" display+board? What is the price for shipping to India (pin code; 700033)? I was thinking of upgrading my OM2 (with Duet v0.6) with a touch-screen solution.

Thanks
Sumant

I only sell the board and optionally the cable, here [www.escher3d.com]. You can buy the complete kit including 4.3 inch display from Think3DPrint3D here [www.think3dprint3d.com].

In response to a previous request, the new (version 2.0) board includes brightness control. It also supports connecting the SD card socket on the display to the connector on the Duet WiFi.]]> dc42 Ormerod Sat, 15 Oct 2016 12:55:39 -0400 https://reprap.org/forum/read.php?340,452641,714104#msg-714104 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,714104#msg-714104 Great work as usual!

FYI I have never had to pay UK import VAT when buying these displays one-off from China.

I ordered a 7" screen from the link on your page a few weeks ago. It came in less than 2 weeks and like you nothing payable on receipt. The cost is way below import duty charges but I was expecting VAT. Must be something to do with the gift box ticked on the transport label. :)

You pay VAT on goods over £15 and on gifts over £34. There is no customs duty on anything less than £135.[www.gov.uk]]]> trevmas Ormerod Tue, 07 Jun 2016 13:07:55 -0400 https://reprap.org/forum/read.php?340,452641,671983#msg-671983 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,671983#msg-671983
Currently was have no facility for controlling the backlight brightness, so it always runs at full brightness. I presume you want to dim it? The prototype had this facility, but I dropped it when we dropped the 3.2" display, because the replacement displays from Itead had no facility for varying the brightness. However, most of the displays people are using now do have this facility, so I will probably add it in the next revision of the board. It would be retrofittable to existing boards by removing one SMD resistor and adding a wire.

I guess another alternative would be to make the colours configurable, then you could use a grey background instead of white.

Older versions of the firmware did have a blue background, but after comments that the UI looked a bit retro, I redesigned it using a more modern style and a white background.

This was the only 7" display I could find in the UK, as I didn't want to have import duty or wait for stuff from China. It cost about £36.88 in total and arrived in 4 days.

I would like to ask if it's possible to adjust the brightness of the backlight on the LCD using the Paneldue firmware.

I see some of the earlier photos have a blue background, but the Paneldue software for the 7" has a white background?

It's a lovely bit of kit for adjusting printer settings on the fly, when my laptop is elsewhere. I went for the 7" as we use the 3d printer on open days to show off student projects, and so it's great to be able to see what the software is doing, without having a PC nearby.]]> Mitch Ormerod Tue, 07 Jun 2016 08:14:12 -0400 https://reprap.org/forum/read.php?340,452641,660209#msg-660209 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,660209#msg-660209


These show the 7 inch screen. 5 inch and 4.3 inch screens are also supported. Up to 5 heaters can be displayed using the 4.3 inch screen, or 7 using the 5 or 7 inch screen

The choice of processor was driven by the following factors:

- Enough pins to drive low-cost touch screens having a 16-bit parallel interface.

I started off designing it around a ATmega32u4 with an extra 8-bit latch to provide more output pins, but it quickly became clear that it provided insufficient flash and RAM. That's when I moved to the ATSAM3S2B. It would be possible to use a more complex firmware update procedure involving uploading new firmware through the serial port via the main board, but that would require even more support in the main board firmware, which I want to avoid. The processors costs me about £2.60 each in quantity, so there isn't a very great saving to be made anyway.

hilarious, isn't it: you think, "oh i know, i'll add a few extra GPIOs using an I2C or SPI driven digital GPIO chip, because that'll be cheaper, right" and ehhmmm no :) it's much much cheaper to add an *entire processor*. yeah i guess the atsam is sensible if it's the same one as in the duet.]]> lkcl Ormerod Wed, 04 May 2016 12:53:11 -0400 https://reprap.org/forum/read.php?340,452641,660128#msg-660128 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,660128#msg-660128
- Enough pins to drive low-cost touch screens having a 16-bit parallel interface.

- Easy firmware updating without additional hardware. This is why a USB port is provided. Duet users were already used to using bossac to update their main firmware over USB, so it was logical to use a micro USB port to update the PanelDue firmware as well.

- Enough flash memory and RAM

PanelDue is not SPI based. Even low res mono graphics LCDs such as the 12864 place a substantial load on the main processor. A high res display with 16-bit colour such as the ones that PanelDue supports would need about 500 times the amount of data to be generated by the main processor and transferred over the SPI bus. This is totally impractical. Therefore, PanelDue has its own 32-bit processor to drive the display. It uses async serial comms to the main board, which also allows much longer cable lengths than for SPI or I2C based displays.

cool. to many that would sound ridiculous - to put a 2nd EC equivalent to the one on the duet itself on a daughterboard to drive an LCD, but i'm familar with ECs, i'm using one in the EOMA68 Libre Laptop: the extra memory in the EC used for the display would act as a buffer. communication via the UART would be reduced to "commands and status". I Get It :)

what's the processor chosen on the paneldue? [edit, below: found it] reason i ask, is: the 64-pin variant the STM32F070 is around $1.20, you wouldn't need the STM32F072 (that's the USB-based version, aka "crystal-less" but actually what it does is PLL-locks the main clock frequency to the host USB DM+ and DM-, ST then charge an extra $0.50 for the privilege... saves board space and hassle as far as i'm concerned, but you're not using USB here so the STM32F070 would do) - it's one of the cheapest highest-functional highest-speed ARM Cortex processors i've yet been able to find... that is also easily-supported by libopencm3. i've written a GPLv3+ LCD driver for the HX8357D based on analysis of the adafruit and the linux kernel driver code, so _that's_ taken care of.

btw the HX8357D also has an 8-bit, 16-bit and 24-bit parallel "bus" mode (not the same as RGB/TTL) so you could actually do pretty damn quick screen-updates... *without* needing a relatively-expensive EC that absolutely has to have an RGB/TTL interface. the LCD manufacturer i found provides access to *all* the different modes of the HX8357D controller IC - RGB/TTL, SPI (3-wire), SPI (4-wire), 8-bit bus, 16-bit bus, 24-bit bus, and a couple more, i think.

You can reduce the cost of a PanelDue setup by.purchasing the control board from me or Filastruder, buying the display direct from China via eBay, and making the cable yourself (I include connectors with the board). Naturally, a complete kit of board + display + cable purchased in Europe or the US will cost more.

apologies, i may not have made it clear by sharing the information about the components that i have sourced from other PCB projects: i'm a Libre Hardware and Libre Software PCB and EC design engineer: i'm not looking to buy a control board, i'm looking to share the benefit of some design, purchasing and component sourcing experience with you from a large and libre hardware project that i'm running, so that you can evaluate that knowledge and information with a view to reducing the BOM and the cost of a future version of the PanelDue.for future buyers.

the supplier that i found of LCDs is in china: they supply direct (they don't do ebay). they manufacture on-demand, and their prices are extremely good - the lowest EC-compatible-without-absolutely-needing-RGB/TTL i've ever been able to find, and i've been looking for a *long* time. i was quoted $USD 25 for the exact same 3.5in 480x272 plus CTP arrangement from one supplier - this one is $8. they would probably do a 5in display for around the $12 to $14 mark, including CTP.

if you're interested and can meet a group buy MOQ with the team at wedo3dprinting of say 100 units absolute lowest quantity, i can ask them what they can do, if you like. they have a full range of LCDs in these small sizes - 320x240 all the way up to 800x600. their 1024x600 is also extremely competitive, b:t:ut it's a bit odd power-wise and they don't get many orders for it. the rest are large volume so the prices are extremely good.

[update: found the wordpress site with a brief spec of the paneldue]

found it: [miscsolutions.wordpress.com] - ATSAMS3B. which is [www.atmel.com] yowser - $3 in volumes of 3.5k. so it'll be $5 and above in small volumes from digikey... hoo-boy [www.digikey.com] yep, $6 in qty 1... yowch.

compare that pricing to this: [www.digikey.com] which is $2.66 for QTY 1 and drops to $1.30 for 2.5k

when it's the main component of the board, $5 down to $2 is quite a big drop.]]> lkcl Ormerod Tue, 03 May 2016 20:43:15 -0400 https://reprap.org/forum/read.php?340,452641,659934#msg-659934 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,659934#msg-659934

I am pleased to announce that manufacture of my touch-screen controller for the Ormerod has commenced.

very cool. it reminds me of the HX8357D-based touchpanel / lcd that i am using in the EOMA68 Libre Laptop (as a mouse trackpad where you can display buttons actually on the display). i take it that the paneldue is SPI-based? the HX8357D driver chip is SPI-based, and has a linux driver as well.

you may be interested to know that i found a company that can sell an HX8357D-based 3.5in 480x272 colour display for $USD 8 with a MOQ of 250 (i will be buying a batch in the next few months). that's $8 *including* the capacitive touchpanel pre-mounted, which is I2C-based. you need arouuund.... 10 to 12 pins to run the thing properly: adafruit have something similar on their website - same driver IC - except that their product is a resistive touchpanel.

now, i mention about this LCD because by the time it's got to the shop in the UK, the sale price is up to 75 GBP (arouuund... what.... $USD 100 or so?) which is a *huge* jump. the LCD i found is powered from 3.3v, has modest power requirements: you need a step-up IC for the backlight (a SY7201 would do, if memory serves me correctly), total PCB cost including components would be around... $7. the PCB's size would also be tiny (40mm x 25mm at a guess - enough to take a 12-pin header, the 50 pin FPC header for the LCD, and house the SY7201) as the HX8357D is already mounted on the back of the LCD.

what do you think?

[update: found and checked the duet 0.8.5 paneldue header pinouts - it's a UART! intriguing for an LCD. the lower-cost LCD then would need to be connected to the main expansion header unless you put another EC such as a $1.50 STM32F072 or blech arduino onto the PCB]]]> lkcl Ormerod Tue, 03 May 2016 08:55:01 -0400 https://reprap.org/forum/read.php?340,452641,595358#msg-595358 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,595358#msg-595358 dc42 Ormerod Fri, 11 Dec 2015 04:00:44 -0500 https://reprap.org/forum/read.php?340,452641,595283#msg-595283 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,595283#msg-595283 Taz-dig Ormerod Thu, 10 Dec 2015 21:14:54 -0500 https://reprap.org/forum/read.php?340,452641,595241#msg-595241 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,595241#msg-595241

Has anyone had success on Marlin via RAMPS1.4?

Been using Repetier-Server and a tablet, but its a bit of a faff and this looks much better.

As far as I know, nobody has added software support for it in Marlin yet.

OK - so my option is to use a Duet board. Thanks for the quick reply.]]> Phytone Ormerod Sat, 08 Aug 2015 16:58:53 -0400 https://reprap.org/forum/read.php?340,452641,543714#msg-543714 Re: PanelDue (touch-screen controller for Ormerod) availability https://reprap.org/forum/read.php?340,452641,543714#msg-543714

1. I have confirmation from a customer that this display [www.ebay.co.uk] also works with the PanelDue...

Ditto, the two I ordered arrived safe and sound a couple of days ago are very well made, both screens clear and responsive

Found that a USB cable had the exact same wire colors inside and that made installation very easy, the pictures on the documentation page was a great help - thank you much!
