Testing a FrSky Neuron ESC. You need to use BlHeli_32 on your PC to configure it. The BlHeli program offers several ways to connect. I originally used an Arduino nano, flashing the nano from the BlHeli program.

I have also used an Arduino Pro Mini, connected to the PC using a FTDI type device. I just "told" BlHeli it was a nano an flashed the Arduino then used it like the nano.

Having looked at what the Arduino was doing I came up with this. You just need a FTDI type device, a diode and a resistor. I just tested it and it works fine.

That's very interesting Mike.

On the surface that appears very similar but not exactly the same as the old FrSky FUC-1 programmer for the old D8 modules and receivers which when it turned up came with FDD-Lite printed on the back.

You could then turn it into a upgrade tool for smart port devices by adding a FrSky SPC which turned 4 wires into 3 and as far as I can see only included a diode but not your pull up resistor.

Yes, but the FUC-1 outputs inverted serial while the FTDI is non-inverted. The diode is polarised the "other" way round. I did think could we use a FUC-1 then remembered it was inverted!

This is the same principle.
