Hello guys. I got two STMF411RE Nucleo Boards and i want to start 10KHz pwm signals on each one of them with 25 microseconds delay between them and i MUST use an external trigger signal (Main synchronization computer) to trigger those STM's to create pwm signals. My main computer generates %25 duty cycle and 100 microseconds period on 10 KHz pwm signals and i tried to trigger my STM's with those signals but i couldnt achieve it. I used timers on Trigger mode with OPM mode ON so that i thought i could generate pulses at the same time that my Trigger pin is Triggered by the main computer synch-signal. But i think that pin is not getting triggered at high speeds such as 10 KHz because i couldnt get a signal out of the output pin. I could press a button and trigger it and generate a pulse with my hand and at another project i approached with the same technique but i worked between 1-100 Hz interval. Here are my timer configurations;
and i am using an FPGA to generate the main synch-signal and it is working perfectly fine generating %25 duty cycle 100 microseconds period of 10 KHz signals on each output shifted with 25 microseconds delay. Is there anyway to achieve this ? I am very new to working with STM Microcontrollers so there might be a lot of basic stuff that i am missing right now but i did my best now i need your help once again guys 🙂 Thanks to you all.
