Firmware for OpenEVSE controller used in OpenEVSE Charging Stations sold in the USA, and OpenEnergyMonitor EmonEVSE units sold in (UK/EU).
Based on OpenEVSE: Open Source Hardware J1772 Electric Vehicle Supply Equipment
TODO: add notes about USA OpenEVSE
AUTOSVCLEVEL(autodetection is designed for split-phase)
MAX_CURRENT_CAPACITY_L2 32(limit for single-phase charging in UK/EU)
EmonEVSE (non-tethered type-2 EVSE unit)
PP_AUTO_AMPACITYenabled to set max current based on non-tethered cable connected
THREEPHASEenabled to calculate three-phase energy
Firmware compile & upload help: firmware/open_evse/LoadingFirmware.md
$ avrdude -p atmega328p -B6 -c usbasp -P usb -e -U flash:w:firmware.hex
ISP programmer required e.g USBASP
This only needs to be done once in the factory
avrdude -c USBasp -p m328p -U lfuse:w:0xFF:m -U hfuse:w:0xDF:m -U efuse:w:0xFD:m -B6
If writing eFuse fails ISBasp may need a firmware update
Tip Jar: I developed/maintain this firmware on a volunteer basis. Any donation, no matter how small, is greatly appreciated.
