Hi I program a STM32F103 chip and work on a GPIO driver. The specs tells you clearly: The peripheral registers have to be accessed by words (32-bit) 9.2 GPIO registers RM0008.It doesn't use the word must be accessed. (Im planning to use the specifica...

Hi I am working on a drivers for the various peripherals on the STM32. Let me take the GPIO as an example. GPIO BSRR is a write only register that I want to read and I need to read back always 0x00000000. Why?I made a bit-field struct on the whole GP...

Dear reader,I have a question about the use of TIM1 on the Blue Pill STM32F103. I want to build a synchronous Buck Converter using the Blue Pill and need to use PWM on TIM1 ch1..3 with its complementary outputs and the programmable dead time for that...
