Hello,
I'd like to activate/deactivate an CAN termination resistor using the software. The goal is to not put a hardware jumper and allow me to set or unset the resistor without the need to open the case.
I think I can do it like this :
ZT_ON signal is one of teensy 3.2 digital PIN (D6). U4 is an optocoupler. ZT is the resistor I want to activate/deactivate.
Can someone give me advices about this circuitry ?
Thank,
Manu
