Hi I have been using Arduino IDE to program bluepill (STM32F103) using Roger Clarke’s repo GitHub - rogerclarkmelbourne/Arduino_STM32: Arduino STM32. Hardware files to support STM32 boards, on Arduino IDE 1.8.x including LeafLabs Maple and other generic STM32F103 boards and it compiles, program fine…

What if you upload #include <Arduino.h> #define LED PC13 void setup() { pinMode(LED, OUTPUT); } void loop() { digitalWrite(LED, HIGH); delay(1000); digitalWrite(LED, LOW); delay(1000); } with PlatformIO?

Because I was reading this post and he said the internal LED pin in his bluepill is PB2 not PC13 and that is his reason for not working. So to isolate this I put a LED on PA5.

STM32F103 Bluepill said upload is finished but program won't run
