Hello, I'm having trouble reading from external ADC which needs a maximum time of 10ns from the falling edge of command (I'm giving it from a TIM4 PWM mode 1, 300ns active, 100kHz frequency). I'm using TIM3 as a slave timer from TIM4, one shot and TI...

thanks for the answers. After througholy reading the manual of the ADC, it seems I misunderstood the requirements of 10ns (it the maximum time after another line goes down for the data to be ready to be read). I'll try to reduce the speed and see if ...

My apologies, the checks are indeed active but if you click over CM4 the rtos setting is desabled

also, does the cubemx put together both free-rtos and threadx or if I choose threadx it superseed the free-rtos?many thanks

sorry I've read now I've answered an already given answer (with the same procedure to swap resistor)

STM32 H745. Is it possible to trigger a dma transfer from memory to SPI on rising/falling edge of pwm generated from a timer?

I've created a project for stm32H745 (dual core) and add the threadX support from software package, but I see it only for the CM4, not the CM7 (and I have also free-rtos selected which is enforced for both). Is it correct?
