I've been trying to figure out how to upload a code to a STM32103c8T bulepill board. My setup is
1- MacOs Catalina 2- STM32103c8T bulepill board 3- SLAB UART USB-TTL CP2012 V3.0 4- Platformio IDE 5- STM32 CUBE Programmer software which detects and connects to my board through UART. meaning that It has no problem connecting but there are issue with setting up the Platformio
BTW I am new to the ARM world and I bought this board to examine its speed and deep sleep and interrupt, I mean all the things that an Arduino Uno can't do.
The thing is I have no idea on how to setup the platformio.ini File to comunicate with the board using the UART method and not requesting ST-link dongle!
What I have now in Platformio.ini is:
[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino
upload_protocol = stlink
upload_port = tty.slab_usbtoUART
and when trying to upload the program i get:

I just need help getting the system talk to each-other and see each-other
P.S. I want to go as bareMetal as possible and not to use arduino firmware HAL
