emonTX V3 Firmware Backup or Editor?

Submitted by Anthony_S on Thu, 23/01/2014 - 11:25

Is there a way I can access the firmware already written to the emonTX V3 i.e. backup or just view it? I'm using a USB to UART through Arduino.

Cheers

Anthony

Not that I know of. The default firmware is https://github.com/openenergymonitor/emonTxFirmware/tree/master/emonTxV3... with the RF frequency set according to the version of the RFM12B fitted.

Thanks for replying, regarding the default firmware can I view this on the emontx or can you only upload/write to it?

The firmware can't be read off in human readable form. The .hex files on the github repo are exactly what is running on the emonTx V3 bought through the shop + Optiboot Arduino serial bootloder. See techincal wiki for upload instructions: http://wiki.openenergymonitor.org/index.php?title=EmonTx_V3

Thanks for the help.

So If I want to put just say put emonTXV3_currentonly firmware I just have to compile the example and upload it or do I have to flash the default firmware first

Just compile and upload. That will overwrite the "factory-loaded" sketch in any case.
