I'm trying to hook up my OpenEVSE to a Raspberry Pi using this manual. I've bought both a FT232RL (FTDI) USB cable and a PL2303HX cable. When I connect the pins as described the EVSE boots and the display turns on. However, no matter how I connect the cables, I can't get any communication going between the raspberry and the EVSE.
When trying to connect using:
screen /dev/ttyUSB0 115200
I get a blank screen, entering the command $ does not do anything (in fact, the $ doesn't even appear on the command line). /dev/ttyUSB0 exists and points to the right device.
- Do I need to enable the RAPI somehow? Or is it enabled by default (FW 3.10.3)?
- Does anybody have experience using PL2303HX or FT232RL?
Thanks for your help!
