Question: Flashable image for STM32?

[retsifp]

Hello!
I really love your project, in fact I already bought one of these displays and as soon as I have some time, I will build one myself.

But I have one question: Is there a chance, that you provide a compiled image for the STM32? 😄
As far as I can see, I only need to modify the ESP8266 code for my needs, so this would save me a lot of time 😉

Well yeah, but it should be straightforward for you to build the firmware yourself.
You just need a baremetal gcc arm toolchain and do a "make" command. No weird dependencies.

Just FTR, I only had to install gcc-arm-none-eabi on my Debian system and run a make inside the stm32_application folder.

There were some errors, I could fix them by adding -std=c99 to the CFLAGS inside Makefile and adding #define asm __asm to main.c and gde043a2.c (I know, it's a dirty hack, but it works 😉).

Now I have a firmware.bin, I hope flashing works... 😉

Yes you are absolutely right, c99 is missing in the Makefile, the reason it works for me is cause I use gcc5 probably (and c11 seems to be the default mode). About the __asm bit I have no idea, I guess has something to do with the compiler version too :) Thanks!
