User Interface, Car PC, etc, systems are best handled externally by something that starts up and shuts down with the ignition switch and can suck as much power as your home PC. OVMS has to keep running, in as low power mode as possible, as telematics are required even when the car is off.</div><div class=""><br class=""></div><div class="">Regarding ESP32, that is top of our shortlisted devices for wifi/bluetooth. But, it depends on release schedule. We want OVMS v3 to be FCC and CE certified, and that means we must use FCC+CE certified modules for the comms parts.</div><div class=""><br class=""></div><div class="">The overall goal is for OVMS v3 to be the microprocessor, power, CAN, USB, ethernet, wifi, and bluetooth, as a base module. Then, everything else (including cellular) are optional plugin modules. We could make wifi+bluetooth optional, but I suspect that they will not add dramatically to the cost/complexity to include as standard. This has got to go in an automotive environment, so plugin modules will most likely go on some sturdy headers on the board.</div><div class=""><br class=""></div><div class="">Regards, Mark.</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On 2 Feb 2016, at 3:34 PM, Julien Banchet <<a href="mailto:jaxx@jaxx.org" class="">jaxx@jaxx.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class=""><div class=""><div class=""><div class=""><div class=""><div class=""><div class=""><div class=""><div class=""><div class=""><div class="">Hi,<br class=""><br class=""></div>I love the OpenCV part, though I'll have to find a way to retofit powersteering and brake actuators in a Twizy, that said, it all shoots way beyond the scope of OVMS (even a v4/v5) imho... but, but, but... an OVMS module shall be the bridge and the low-level comms offloader for an optionnal "Hyper Smart OpenCV Dashboard Music Streaming thingy" that a sister project can take over :-) (my opinion again)<br class=""><br class=""></div>So yeah, It needs to be beefy, and the ESP32 seems to be a nice candidate and embeds by itself a nice load of functions (Wifi and BLE!)<br class=""><a href="http://www.pighixxx.com/test/2015/12/esp32-processor-pinout/" class="">http://www.pighixxx.com/test/2015/12/esp32-processor-pinout/</a><br class=""><br class=""></div>It has no CAN, but it has SPI (can't tell how many on this pinout) and plenty of HS GPIOs for native or soft UARTs.
