Great Work Phonog ! I've had a few of those in my drawer for a long time but will now start testing a bit.
I've been doing Lots of CANbus using the MCP2515 but always had to stick to standard Arduino Nano to avoid the dreaded 3.3V - 5V Issue.
Yes, transceivers do a great job but the higher the component count the lower is the reliability.
I've been using the Atmel SAMD21 (3.3V) but could not interface the MCP2515 directly. Now I can have more Mips/ More Memory
Can Tranceivers : Check into this: http://www.ebay.com/itm/SN65HVD230-CAN- ... SwepJXbQj6
I've been using those on an arduino Due project.
Is there anything you'd like to be tested in perticular ?
My Ultimate dream : CANbus bootloader !
I was just about to lookinto it for the Arduino Nano or the SAMD21.
I did work an SDCard(SPI) bootloader for the SAMD21 and was about to look into a CANbus version ...
But this 2$ PCB just tells me I should try on the STM... I'd be willing but I would like to know if someone else has interest to help out.
I could even work into the STM32Loader.py to support out work.
Imagine this, you seal your mini project in a proper casing to avoid environmental issues and you fidure out later you would like to add a new feature.
OKOK , I know you guys all do it best the first time around !
