Hallo,
I really appreciate this incredible open-source work, thanks a lot.
I am new to ARM (STM32) development, coming from the simple arduino world. I am working on a DIY audio appliance controlled by a touch screen and am looking for a well-supported combination of TFT controller and underlying OS for 4"-7" inexpensive TFT, running on inexpensive maple mini clone (STM32F103xx). The actual audio will run on a small PC, this is for the control display and a bit of control functions.
I think for STM32F103 the only viable connection is SPI. For this TFT mid size I found out that the only controller supporting SPI is RA8875 (?). I think I would use the resources offered by ChibiOS but this thread talks about very inefficient SPI implementation in ChibiOS.
Please may I ask for recommendation of well supported and tested combination STM32F103 + TFT 4-7" controller (usually not available with the ILIxxxx family) and the underlying OS? I do not know if bare metal would be appropriate as I would need at least threads. These TFTs cost more than a few dollars and I do not want to order stuff which will not be usable.
Thanks a lot for any suggestions/recommendations.
Best regards,
Pavel.
