OpenGD77

New version to perhaps fix the battery voltage https://opengd77.com/downloads/DM1701/Firmware/5514b8779f4edf7ea6e439fbf3fbd1a8df0ea2ea also in the Latest folder I averaged your two readings and used this to calculate a new battery divider coeffecient which I hope will be better But it may still nee...

Hopefully when you try the latest firmware I posted, the CPS will recognise as UV380 type Programming would not work correctly as GD77 type, because the UV380 and DM-1701 etc do not have EEPROM, and the CPS has to send commands differently to write all data to Flash memory, even though the address ...

marked on screenshot, for your information


CPS uploading to DM-1701 works perfect!
