Support to STM32F103C8T6

[carloshcarvalho]

Hello, I would like to know if it is possible for this library to work with the stm32f103c8t6 cards, currently when I try to compile I get an error, and I can not change the library to work.

Try thiis config:

[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
board_build.mcu = stm32f103c8t6
board_build.f_cpu = 72000000L
framework = arduino
monitor_speed = 115200

Hello, I am currently experiencing the same issue with STM32F4. I believe it is because the different ways on handling the pins

Try thiis config:

[env:bluepill_f103c8] platform = ststm32 board = bluepill_f103c8 board_build.mcu = stm32f103c8t6 board_build.f_cpu = 72000000L framework = arduino monitor_speed = 115200

What do you mean by this config? Where I can insert it?
In my implementation, the error is like this:

Any help will be appreciated in tackling this error.

Upgrade Your level to VScode+Platformio: https://platformio.org/
This config for platformio.ini file

Second way is: check this libraries in your classic arduino IDE:
Keypad-master_2.zip
Keyboard.zip
STM32-master-Keypad.zip
