I am using an stm32F103 and have configured PB4 as a output pin and this works correctly. However when the chip is reset, this pin is automatically pulled high. It appears that this behavior exists because of the pin's dual use as NJTRST. Is there a ...

I am trying to use pin PA8 as a PWM output using timer 1 on channel 1 for a stm32f103rct6. I have successfully programmed pins PA9, PA10, and PA11 to provide PWM output on channels 2, 3, and 4, but when I do the same for PA8 on channel 1, I do not ge...

I am trying to understand the external interrupts for the STM32F103C8. It seems that I can attach an interrupt to any of the PA or PB pins. The first 5 pins (0-4) seem to have unique IRQ handlers, whereas pins 5-9 share a handler as does 10-13. When ...

I used STM32CubeIDE to create the project. The configuration that I used for the i2c is attached. I generated the code and added the following code in the "USER CODE BEGIN 2" section right after the call to MX_I2C_Init(). I made no other changes. uin...
