KL25Z UART updating tpm period

Question asked by Nícolas Bordignon dos Santos on Oct 8, 2017

Hello everyone 
I have 8 servos in PWM channels of KL25Z that i want to control via serial from my Visual Studio solution.

I'm using UART1 to receive data and update the tpm period that control the servos.

My problem is that i get a HardFault when i call the UpdateServo function from the UART1 IRQHandler.


I thinking it's happening because i'm calling it from the interrupt handler.

Any idea how i can fix this problem?


MCUXpresso project are attached.


Thanks for your help
