Sigma-Delta ADC STM32F373 calibration problem

Hi,I have connected three channels of the SDADC in the STM32F373 with an external voltage reference of 1.225V. The selected mode of the ADC is Single-ended zero-volt reference mode, and i am reading these channels using the "injected conversion" as i...

I want to use the complementary PWM feature in counters except for two advanced timers(because I have a large number of pulses).

I have mastered and timed two timers and can produce both pwm and not pulse. But my problem is that there is no dead time between pulses.Can you suggest a way for me to have an option like ch1ch1n in other timers that have dead time?

complementary PWM I want to create the complementary PWM pulses in timers, for pulses with a specific dead time.

I actually need 6 Plus. (3 pulses (not) are other pulses). I have generated 4 pulses with two timers 1 and 8 and I need to generate two more pulses, but I can not produce dead time with advanced timers. I have used advanced timers and I need to have ...

Problem with code slowness

Hi all,​I am using the Delay​ function as follows.static void Delay(volatile int d) {  d = d*20;  while (d--) asm volatile("NOP"); }​​However, sometimes when adding printf code, Delay function becomes slow.So, when I analyzed the cause, I was able to...
