Hi,
I configured 4 outputs from the MCUXpresso
tool as shown by the function SCTimer_1_int generated automatically by the tool (see below).
I added the LookSpeedCtrl function that I need to see if the pulse value changes on the inputs to understand if there has been a block of the connected devices.
What I see is that if I activate the code as shown under the command of the fourth output it no longer works. Instead if I remove the LookSpeedCtrl function it starts working again. Where is the problem in your opinion? What am I doing wrong?
Regards
