Greetings to all makers

MARLIN 2.1.2.1

I have a problem I hope you can help me, I am installing a tinyboy2 but I can not get it to work, with the statement in Configuration.h "#define OLED_PANEL_TINYBOY2" does not work at all, but if I change to "#define U8GLIB_SSD1306" the oled works correctly, but I can not use the encoder and buzzer to navigate through the menu, add the line in Conditionals_LCD.h ...

//} 128x64 I2C OLED LCDs - SSD1306/SSD1309/SH1106
#if ANY(U8GLIB_SSD1306, U8GLIB_SSD1309, U8GLIB_SH1106)
#define HAS_U8GLIB_I2C_OLED 1
#define HAS_WIRED_LCD 1
#define DOGLCD
+#define IS_ULTIPANEL 1
#endif

The encoder only works the central button to enter the menu but no pin in the AUX4 line does anything, I have checked it, I do not know if I need to assign pins in the ULTIPANEL section or I need to configure some other parameter, it should be noted that I am using the diagram published here, using the 4-pin I2C connector and AUX4 pins 31,33,35,37 for EN1,EN2,BTN,BEEPER, any comments or suggestions are welcome.

I will leave my code as I have it right now.

|Configuration.h|

//
// SSD1306 OLED full graphics generic display
//
#define U8GLIB_SSD1306

|Conditionals_LCD|

//} 128x64 I2C OLED LCDs - SSD1306/SSD1309/SH1106
#if ANY(U8GLIB_SSD1306, U8GLIB_SSD1309, U8GLIB_SH1106)
#define HAS_U8GLIB_I2C_OLED 1
#define HAS_WIRED_LCD 1
#define DOGLCD
+#define IS_ULTIPANEL 1
#endif

In pins_RAMP.h I don't have any parameter to configure ULTIPANEL only NEWPANEL, I am not very good at programming, I understand the most essential to configure marlin, I have already done it in 10 machines without any problem but this oled is causing me errors.

Now I have modified marlin. The machine will crash and restart when printing with OLED screen, but it can be used normally when connected to the upper computer. Have you encountered it

Hello, I want to apply OLED screen to my ramps 1.4, but the code structure of marlin 2.0 firmware is too different from that of V1. Although I can implement it on Marlin 1.1.9, it is always wrong in 2.0. Could you give me a modification method for 2.0, including SD card module

Marlin 2.0 already supports these screens. Exactly which configuration options you use depends on which variation you built.

Has anyone tried this on a Creality 4.2.2 board that comes by default on the new Ender3s? I've messed up the lcd trying to explore a color change, and this looks like a great option to build.

The trick is that you would have to find one of the i2c busses on that stm32f1 exposed to a pin header.

You could build the spi version and connect it to the existing header, maybe with soft spi enabled? not sure.

Thank you! I got the SPI version working with Klipper. Gonna try Marlin now.

EDIT
I figured out the pin layout of the lcd cable after a lot of fiddling, and was able to make the display work with Klipper firmware's software SPI. I'll try and get it to work with Marlin, but I don't have high hopes there.

I don't know what patch you applied and to which version of Marlin, and I can't find any trace of my patches in your Configuration.h. A good point to start if using Marlin 1.1 is here.

Good grief. Why are you using marlin 1.x in 2021?

Don't. Download marlin 2.0, transcribe your configuration file to the new version, compile that. No patch needed.

FYI, my SKR 1.4 crashes randomly without U8G_I2C_OPT_FAST and of course shifts the display with it.

This turns out to be a known issue in marlin with no resolution in sight.

Oh i see. In the appropriate section of ultralcd_DOGM.h, change "#define U8G_PARAM (U8G_I2C_OPT_NONE | U8G_I2C_OPT_FAST)" to #define U8G_PARAM (U8G_I2C_OPT_NONE)"

Over the weekend i cobbled my own controller with an sh1106 1.3" display based on diagrams and information here. Will be using it with an skr 1.3

I'm using marlin 2.0.7.2 and noted the OLED_PANEL_TINYBOY2, which works except for it is for ssd1306. Pretty sure i made the correct change in the u8g conditionals for that.

I'm unsure where to remove U8G_I2C_OPT_FAST?

Edit: Do not edit the u8g conditionals. Just #define U8GLIB_SH1106 instead of OLED_PANEL_TINYBOY2

Re: DIY Tiny OLED I2C full graphics controller

yet-another-average-joe — Thu, 03 Dec 2020 20:43:13 -0500

Issues (vertical shifting and crashing) are solved on my side by slowing down I2C to 100kHz instead of 400kHz (default in u8glib).

Just remove the option U8G_I2C_OPT_FAST (where ? depends on the display)

Horizontal shifting is simply related with the OLED. The 1.30" is a SH_1106, not a SSD1306.

Re: DIY Tiny OLED I2C full graphics controller

yet-another-average-joe — Tue, 24 Nov 2020 22:05:05 -0500

Hi,

I'm experiencing weird issues with OLED displays on a brand new SKR 1.4 Turbo. I tested with two OLEDs (0.96 and 1.3) and a rotary encoder. These parts are known good. I played a lot with them, developping my own menu library for Arduino.

With the 0.96", the display is perfect. With the 1.3", I get the "shift bug". As far as I know, these modules have pullups on SCK and SDA. Never had such a problem with Arduinos and STM32s using u8_glib and u8_glib2 with OLEDs.

Other issue : the encoder does nothing. It is connected as it has to be, but nothing. No menu. I use the pins 2 & 9 on EXP1 (=GND & 0.28), and 2, 6 & 8 on EXP2 (= GND, 3.25 & 3.26). These pins are defined by default in pins_BTT_SKR_V_1.4.h :

#define BTN_ENC                        EXPA1_09_PIN  // (58) open-drain
#define BTN_EN1                        EXPA2_08_PIN  // (31) J3-2 & AUX-4
#define BTN_EN2                        EXPA2_06_PIN  // (33) J3-4 & AUX-4

EXPA1_09_PIN == P0_28
EXPA2_08_PIN == P3_26
EXPA2_06_PIN == P3_25

(according to Intellisense in VSCode)

I configured Marlin with just "#define U8GLIB_SSD1306", and got it to show on the OLED (perfect on the 0.96", shifted on the 1.3). CouId there be some timing issues ?

No idea what parameters to play with, I2C or encoder.

t seems the OP's work has been pulled (?).

I'm missing something, but I can't figure...

New fact : even the 0.96" shifts, but not at boot time.

Well, here's mine. I *think* I managed to fix it by adding a 4.7kohm resistor to both SDA and SCL to VCC.. at least, the issue has not returned since.

@ Johetan:

When trying to make my Tiny OLED work under Marlin 2.0.5.3 with the BigTreeTech BTT SKR V1.4, I ran into the same problem as you with that shifted display. I also tried all kind of remedies, such as the ones you tried as well, but with no success...

Finally I looking at the file Marlin/src/HAL/LPC1768/u8g/u8g_com_HAL_LPC1768_ssd_hw_i2c.cp, I saw that there were some commented out statements, which looked as if the developer left them in, not being sure that they should really be removed... So I decommented them, recompiled and uploaded. It's now already a few hours running - and so far no shift in the OLED display :-)

Here are the changes I made in Marlin/src/HAL/LPC1768/u8g/u8g_com_HAL_LPC1768_ssd_hw_i2c.cp,:

184c184

Let's see if this really solves the problem for good...

I'm using an SSD1306 based OLED on an SKR 1.4 Turbo.. unfortunately, I get the line shifting too, and making these changes doesn't make any difference. Has anyone found a fix yet?

Edit: I found this: [www.reddit.com]
Not really a solution, but it explains why it happens, at least..

I didn't add the patch cause there was no dogm_lcd_implementation. h file in marlin 1.1.9 I tried adding it to the ULTRALCD_IMPL_DOGM. h file but it would bring up alot of compilation errors and when I fixed them the oled didn't work, I commented the patch and uncommented #defineU8GLIB_SSD1306 in configuration.h the oled lcd worked but the encoder didn't, I would like to know how to enable the encoder to scroll through the menu and the lcd times out so if you could please help me fix both problems

When you rotate the encoder, does this change the flow percentage?
Could you give us some more information on your setup, and may be photos?

May be you mixed up the two signals? If I am not mistaken, D20 should be connected to SDA and D21 to SCL.

This week I finally got the BTT SKR V1.3 board, which I ordered a loooong time ago. It's very similar to the V1.4 board, but -unfortunately!- the SCL and SDA signals are not available on a dedicated I2C header. Instead, these pins are used for the STEP and DIR signals of the second extruder E1. However, if you only use one extruder E0, then you can use the Tiny OLED display in the same way with tV1.4 , which I explained a few messages above. Here is the way I connected my Tiny OLED to the SKR V1.3:

As for the changes in the Marlin firmware, I applied exactly the same changes as explained abovefor the V1.4 to the Marlin download Marlin-bugfix-2.0.x-SKR13 from Big Tree Tech. With these changes, I got, after some minutes, again the screen shifting problem described by Johetan and I was able to resolve the problem with the same changes as for the V1.4.

Here is the pinout of the MKS Base 1.4.

I just received one the these new 32-bit boards from Bigtreetech, the BTT SKR V1.4 based on the LPC1768 ARM32-bit processor. This board runs well with Marlin2, I use version 2.0.5.3 downloaded from here and compile it with PlatformIo.

Of course, my first question was, how to get my Tiny Oled I2C display controller to work with this new board... As it turns out, this was not too difficult, it was just a matter of finding where to attach the 8 basic display controller pins [VCC, GND, SCL, SDA, EN1, EN2, ENC, BUZ] to the SKR V1.4 board, and how to modify Marlin2 for supporting the Tiny Oled.

The SKR V1.4 has a I2C header that is used for [VCC, GND, SDA, SCL]. For the rotary encoder pins EN1 and EN2 I used pins 3.26 and 3.25 on the EXP2 connector, and for the encoder push button pin ENC and the buzzer pin BUZ I used pins 0.28 and 1.30 on the EXP1 connector of the SKR V1.4. Here a photo and a diagram showing the connection:

As for Marlin2, the changes are very similar to those of Marlin1, just small changes in files Marlin/Configuration.h, Marlin/src/inc/Conditionals_LCD.h and Marlin/src/pins/lpc1768/pins_BTT_SKR_V1_4.h are needed. The changes I made are shown below:

Please note that these changes are for my version of the Tiny Oled I2C display controller, as documented in this thread. I you use any other variant of this project, your mileage may vary...

If you get the problem with the shifted display that Johetan reported above, see also my reply to him - I am not sure if my method is the proper solution, but so far I have not had the problem again...
