PWM one-shot mode stops working after exactly 427 pulses

JustSomeGuy
Associate III

Hey all,

I am using a B-L072Z-WLAN1 that talks to another of the same board using LoRa peer-to-peer. The board I am having issues with is supposed to receive how many pulses to send from the other board, then send them using pwm one-shot mode to PA0. Using a live watch expression on pulsesSent, I found that the pwm stops working after exactly 427 pulses. I am completely lost as to why this is happening. Any ideas?
