Random pulselenght jumps

Hey, I’m having some problems with my Flipsky vx1 remote. When I connect it with the UART port to the vesc it works fine, however, when I try to connect it with PPM it flips out. The pulslength jumps from 1.1500 to 1.5000 randomly which makes it hard to mapp. Would love some help


Try to add a ferrite ring. It helps sometimes with this kind of behaviour.
