  • I have a wifi MCU on one end and a Picaxe on the other. Trying to send ttl from wifi mcu to picaxe rs232 wired TX from wifi MCU to RX on shifter and wired RX on rs232 side to Picaxe. The TX lights on the MCU and the RX lights on the shifter but nothing is happening on the Picaxe. It should be lighting an LED. I have switched the wires every way I can think of and still nothing!

No public wish lists :(
