BTW. Am am not going to change what libmaple does, as plenty of code has been written for it already and expects 12 bit
Indeed, it seems a pure Arduino_Core issue, not a libmaple core one.

Re: Lib for ILI9486 - 3.5 inch 480x320 touch TFT for RPi

Aleksey, do you use this software https://github.com/stevstrong/Arduino_STM32/tree/generic_f4 together with this display lib https://github.com/stevstrong/Adafruit_ILI9486_STM32 ? If yes, please detail what exactly is not working. Unfortunately I don't have any F4 discovery board, so I cannot test i...

Re: Partial / old code for a F4 Maple bootloader

Roger, did you try the raw binary for F4 disco? http://builds.blacksphere.co.nz/blackmagic/

Does this mean that we could turn a black F4 board into a BMP probe? It sounds interesting.

I just added a code example on GitHub for the BluePill and a ILI9341.
This is a very initial state which I plan to extend. Do you have suggestions for any improvements?
No suggestion yet, but it looks nice so far, I am very interested in this project.

I suppose we could download it and include it as part of LibMaple

Re: Should we still use ptimisation level -Os (Small)

-Os does a good job job in general, so I think we should leave it. However, as far as I know, different optimization level flags can be still used selectively for some modules independent on the default one, if necessary. OTOH, the achieved speed also depends on the individual coding style, so it sh...

Re: SD card on ILI9341 display board??

On my TFT board with SD card slot there are no resistors at all on the SD card lines.
EDIT
I use the board with 3.3V.

Re: OV7670, Generic STM32F103RC and ILI9341 display

Having the need to change the byte swap would mean that you are actually loosing a byte (half pixel) from one line to the next, which you recover somehow at the next line.
