I create a TIM8 mode up and down using this Instruction
Then I create a PWM signal using TIM8_CH1
I have another part of my program that read ADC value of 5 signal using DMA.
I want to trigger the reading of ADC 4 time in period (The red circled in figure)
Ie when TIM8 = 0 , TIM8 = 1500 Up,, TIM8 = 2000, TIM8 = 1500 Down memorize them then repeat the cycle conversion .
I use this line in ADC configuration
But i don't know what this 2 line do exactly :-/
And how to verify if The trigger works in the desired Time or no ?
Can someone help me to read ADC in this 4 time
