Hi All

I ahve an E-Coder Mini and i'm looking to create a daughter-board with buttons, encoders and LED's on.

I want to understand what the VT units are that are connected to LEDPRIM and LEDSEC which then have 3 LED's after them

Could someone explain please?

Thanks

I too would like an explanation on what LED- Prim and Sec are. I take it that VT1 and VT2 are MOSFETS but in which situations are they used?

They should be the outputs for encoder and keyboard keys leds. The settings are in the Options->Panel menu (see the attached picture).
For what I know the E-Coder protocol is not open, but you could consider using the TCI protocol.
In a few days I should publish a Arduino (ESP32) library that cover almost every 1.3 TCI command.

You can use it for everything you need.
In the second picture you can see a typical application: an automatic band switch with hw com port for each receiver.

Hi Enzo

I also thought about using TCI for this task but as far as I can see that necessitates a listener between the eesdr and the usb-based peripheral (ie. an alternative e-coder). On the other hand that solution could provide extended functionality over the original e-coder!

I would be VERY interested in seeing your implementation of the Arduino TCI-library (I’m almost solely use STM32 but it shouldn't be a problem porting it).
