Shortly, cookbook says ETR frequency higher than core clock. It seems wrong. I am not sure if the information given is correct.

I am using STM32F030C8T6TR. I have a process that needs to be counted precisely, so I'm connecting a timer oven oscillator with an extenal clock mod 2. How many MHz can I use( for maximum)? I'm using an internal clock for processor, it works at maxi...

In my project, I have to count exact time and I am using very sensitive external oscilator. I configure it as a external timer. I have a certain number of overflow counts and waste values for my count, when it reaches the waste value, I create a capt...

When data size equal to 3 rx buffer last element is true only others are not. I expected all of them is true data. Why it is working like that ? I examine the result on debug modestatic void Init_SPI2(void) { SPI_InitTypeDef SPI_InitStructure;   ...

I try to generete interrupt when CNT register reach any value. But It generete when I enabled to interrupt EGR bit is always zero. when I try to change accept first bit not effected.It is configuration  capture = TIM_GetCapture2(ExternalOSCTimer); TI...
