Arduino for STM32

Posted: **Thu Apr 30, 2020 8:58 pm**

Hello,
I'm currently working on porting the Adafruit 8 bit parallel tft library to stm32duino but I'm running into some issues when compiling.
Here is the full error:

Error compiling for board Generic STM32F103C series.

I'm using a blue pill board with roger's core, which I found here: https://github.com/rogerclarkmelbourne/Arduino_STM32
Am I missing something? Everything I have found points to GPIOB->regs->BRR = CS_MASK being correct syntax. I presume i'm missing a header file or something.

Here is a link to my code: https://github.com/mkengineering/Adafru ... ree/master

Thanks in advance for the assistance!

Check this out... it may help.
