I have an old emonTx running emonTxV3.4 Discrete Sampling version which has been operating without issue for many years reporting to an RPi running EmonHub.
I would like to update the firmware to emonTxV3.4 Continuous Sampling to take advantage of the improved accuracy.
When I try to upload the new firmware it stops working - I suspect I will need to modify some of the pins and variable settings in the sketch but am not sure. Is there a guide / tutorial somewhere listing the changes I need ?
Thanks in advance,
