Sure.

You need to route an EGPIO line to the DA26 port. For a first test you can add a simple jumper on expansion port pins 10/12 to route EGPIO_8 to GEP_7 (= pin 21 on DA26).

You should then be able to use the "egpio" command to test your LED. EGPIO_1 … _8 labels correspond to MAX7317 ports 2 … 9, so to control EGPIO_8, do:
OVMS# egpio output 9 1  # EGPIO_8 on
OVMS# egpio output 9 0  # EGPIO_8 off
(correct me if I'm wrong, Mark)

I wasn't aware there are other cars in need of something like this. I'll think about adding the logic as an option to the vehicle framework, but I can send you some patch to test this on your i-MiEV/clone first.

Michael

I can add for testing a simple led (with resistor) , same as SimpleConsole (twizy OVMS V2), to show car is recuperating, connected to DA26 external expansion port?

As the Mitsubishi code also reads battery current/power level from CAN, it would be trivial to add the same logic there.

The Trio (Mitsubishi I-Miev and clones) does not activate the brake light on recuperation on 2105 and older models, if this is work is very impressive.

Mark,

that looks very good. Not sure about general demand, but I think we should have this to enable simple custom hardware I/O extensions.

For the Twizy, I was thinking about adding logic to control the brake light from the module. The Twizy does not activate the brake light on recuperation, as that's normally (untuned) not very strong. But a tuned Twizy allows one pedal driving, so needs this.

Looking at our case I also think one custom extension board should fit on top of the modem.

Regards,
Michael

It seems the attachments were messed up, so attaching again…

Design layout. Looks good to me, but open to suggestions...

We can make in sets of three PCBs, to keep prices down.

A kit of 5 PCBs + SIP edge connectors + mounting hardware, unsoldered, would be about US$15 + shipping. About US$3/board set. With shipping I don’t think this is worth doing with less than 3 or 5 boards per kit.

Would this be useful?

Regards, Mark.

This is the closest we have today:

That is a bare modem board, with just the sip connectors. The prototype above is a K-line transceiver.

I think it would be trivial, and cheap, to make up what you show. Perhaps just solder ready pads at 0.1” pitch, then the side sip connectors wired to the first row of pads at each edge. Perhaps 5 PCBs in a kit, with sip edge connectors, unsoldered, in a simple plastic bag.

Does that sound like something useful? If so, I can ask the China guys for some idea of pricing. If it is just the unsoldered pcbs + parts, I don’t think it will be expensive.

Mark,

do you know of some kind of prototyping board available that fits to our piggy back expansion layout?

Something like this: https://www.robotshop.com/de/de/cytron-arduino-proto-schild.html

If you have work to do on this DA26 expansion ports, this is pretty cool and well built:
