Hi!I have two PWM signals coming into two MCU pins, that are two TIM4 channels. Channel 1 and Channel 2. I initialized both Channel 1 and Channel 2 to input capture mode on Both Edges and enabled the Capture/Compare Interrupt (Not in slave master mod...

Hi, I basically have two PWM signals going into two pin that are set to be TIM4_CH1 and TIM4_CH2.I setup both channels in slave mode and enabled the input capture mode on Rising mode.When I enable only channel 1 and the code below get executed I retr...

Hi,I have the following function to simulate a positive phase shifting. void TIM3_Configuration_positive_quadrature(void) { TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; TIM_OCInitTypeDef TIM_OCInitStructure; int Period; Period = 1000 / 1; // T...

Hi,I have these two functions ( see below ) that simulate, respectively, a positive and negative quadrature. void TIM3_Configuration_positive_quadrature(void) { TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; TIM_OCInitTypeDef TIM_OCInitStructure; ...

What do you think about about setting channel to rising, reading the captured value, setting the channel to falling, getting a capture and set it again to rising to get the final capture and calculate all the variables?

I'm sorry, could you explain further what can I do to workaround it? "you may query the signal level in the interrupt handler and adjust your interpretation of the time stamps accordingly." Unfortunately I can only use these two channels.

Fixed by setting the mode to the previous one (PWM1) when the frequency function get called.

This is how the waveform looks like when I change frequency after calling positive Quadrature function (the frequency becomes half as well)

Timer Input Capture duty cycle calculation is sometimes complementary

I get same Capture Value when using input capture mode on the same timer

Reading two PWM signals using only two channels.

Function to simulate positive phase shifting changes direction randomly.

Function to simulature quadratures changes quadrature direction randomly.
