I'm sertanly missing something.I have a board with STM32F103 that control fan via PWM and have to check it's speed with Fan's TACH out. TACH out is consistent PWM signal with duty cicle 50% and frequency 80 Hz.Chip is running with 64MHz clock, APB1 i...

try Get_Src_Cap_Message_type = 0x07instead ofSoft_Reset_Message_type = 0x0DIt will populate RX_DATA_OBJ with PD Source capabilities

So, I ended up with reading TIM1 value at the beginning of interrupt with TIM_GetCounter(TIM1);volatile uint32_t FAN1Freq; void TIM2_IRQHandler() { static uint16_t capture1 = 0, capture2 = 0; static uint16_t isCaptured = 0; static uint16_t delta =...

I have PWM output on PA3 (TIM2_CH4) and TACH input on PA1 (TIM2_CH2). Because of PWM timer settings its counter resets at TIM_Period, as @Community member rightly pointed out. Well, im still might use Timer edge detector, but i should find another w...

Thank you. You are both right.First of all, looks like modulo 200 really is one of the problem.So, I moved Timer Input to TIM1 with Period 0xFFFF and Prescale 1000. Capture results in ticks is pretty consistent.Also, now I see, that interrupts are no...
