  • Help. I’m trying to talk to a device that expects RS232 io via a MAX232 chip. Do I have to invert the signals so TXD is TXD# and RXD is RXD#?
    I’m testing connectivity to a Scott Edwards Serial LCD backpack and keep getting garbage.
    Is this a TTL signal inversion issue?

No public wish lists :(
