Be aware the MAX71317 outputs are open drain, so you need a pull up
resistor to e.g. +3.3. According to the data sheet, the current
should stay below 6 mA.<br>
<br>
I've just done a quick test wiring like this:<br>
<br>
<tt>JP1 pin 1 (+3.3) ----- [ 680 Ohms ] ---+--- [ LED ] ----- pin 28
(GND)<br>

pin 12 (EGPIO_8)<br>

Sure.<br>
<br>
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).<br>
<br>
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:<br>
<blockquote><tt>OVMS# egpio output 9 1 # EGPIO_8 on</tt><br>
<tt><tt>OVMS# </tt> egpio output 9 0 # EGPIO_8 off</tt><br>

(correct me if I'm wrong, Mark)<br>
<br>
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.<br>

that looks very good. Not sure about general
demand, but I think we should have this to enable
simple custom hardware I/O extensions.<br>
<br>
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.<br>
<br>
Looking at our case I also think one custom
extension board should fit on top of the modem.<br>

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.
