STM32F103RBT6 mini board ( ebay)

Hello all,

Is the STM32F103RBT6 mini board with tft somthing cool to use for the printer,
I order one, to see how its work, i have not a lot programming skils.

Did sombody tray this board ones, or have some firm/software that i can play whit. Raprap related.

Thanks for the input

Nonaak

is this the board?

you will need programming experience to use this board. reference [www.3dprinting-r2c2.com] for porting of teacup firmware over to arm.

see if an ide is included with the cost of purchase of board from your supplier.


what you have an opportunity to do is become great at programming. no one is going to do your work for you here.

The STM supplies an IDE for their chips and it doesn't require any sort of JTAG, which is nice.
I think you'll find the 20K of RAM on that particular board restrictive.
I've been using one of these
[www.ebay.com]
Which is similar, though different chip and it has more flash and RAM, and ethernet, which to me is a minimum requirement for me to be bothered to rewrite firmware.
I've been writing my own firmware, and it runs, the touch screen makes for a pretty cool jog control.
On the down side there is certainly enough GPIO on the board, but because of all of the additional components, and the way some of them are connected, the layout is less than optimal.
The sample code and in some cases the supplied libraries are appallingly written, and often broken.
If you don't enjoy writing code and pouring over hardware docs I would recommend skipping either.

Those LCD boards are a pretty neat package, I have one of the STM32F103 versions. If nothing else I was going to use it as a touch panel interface for my printer. To run a printer with it you would something like a RAMPS.

I'm not sure how to leverage these cheap boards without creating a mess of wires though. If there was some standard form factor like the Freescale Tower system it would be a lot easier. The closest thing is the Arduino layout, many boards copy the basic Arduino layout but not the Mega one used by RAMPS.

For a touch panel interface you probably want that mounted somewhere convenient for the user, rather than stacked on top of the motor drivers. A small micro plus touch screen communicating to the main board via UART/RS485 would seem to be ideal.

I am currently working on creating a portable ARM firmware based on R2C2 firmware (which was also derived from Teacup). I hope to get it running on STM32F103 series, among others. I have a box full of boards to work on
