The built-in LED stays on
redbeard122 opened this issue · comments
the Built-in LED of the STM32f103C8 which is connected to PC13 stays ON even on an empty sketch.
what is the solution for this issue ?
Have you tried setting PC13 as OUTPUT and HIGH?
The LED is active low I think. So it's ON when you set the pin LOW. With an empty sketch, I'm not sure what the pin is doing. Maybe floating?
