EmonTX v3.2 Firmware

I cannot seem to find a working link to a (compiled) version of the firware for this hardware combination. Please can someone point me in the right direction for compiled firmware (or source) for EmonTx V3.2 hardware.

Somebody has messed around with Github and moved it. It is now very well hidden - it took me ages to find it:

EmonLibCM will work with an emonTx V3.2, the problem is the radio - you need a patched version of JeeLib (RFu_JeeLib) or you can use my rfmTxLib (transmit only) which works equally well with the
emonTx V3.2 or V3.4. It’s available here:

Update to 3-Phase PLL sketch

An updated version of this sketch is attached here. The significant change is this now incorporates a switch to choose between the JeeLibs “Classic” radio format and the new “RFM69 Native” format. Full details of that are posted separately under the heading “The EmonPiCM” (The emonPiCM) which explains when the ‘Native’ format must be used. Although the name of the sketch now includes “rfm69n” signifying the “Native” format, the sketch can be set to transmit using the old “Classic” format to ma…

So, if you would like the latest continuous monitoring, I suggest to take the V3.4 sketch and replace the file “rfm.ino” with rfmTxLib - you might need some small changes to the calls to library functions, but without checking in detail, I can’t say what, but they are quite similar (because I wrote both ).

Here’s a list of all the I/O pins used in various hardware, check for changes between the V3.4 and your V3.2 (e.g. you don’t have DIP switches - those need to be deleted) .
