Re: Power probelms
a) how do you supply PyBoard, at which pins and which suplly voltage.
b) is there an additional circuitry on you PCB.
a) the power of board supplied by LM317, which will change 24V to 5V, then MCP1802 change 5V to 3.3V.
do you give me a email? I can send the schematic to you , thank you

Re: can bus problem
You can use a bytearray. dat=bytearray([0xab,0x30,0x20,0x10,0x00,0x00,0x00,0x00]) can.send(dat, id) You can also use the b prefix on strings: can.send(b'\xab\x30\x20\x10\x00\x00\x0x00', id); With bytearrays its kind of like an array of integers, so you can modify it after the fact as well: >>> dat=...

can bus problem
The can bus API has provided the function 'can.send(data, id, *, timeout=0, rtr=False)', and the data is an integer to send, or a buffer object. If I want send the data is less than 0x7f,which can be expressed by ASCII, it worked well. for example: dat=[0x40,0x30,0x20,0x10,0x00,0x00,0x00,0x00] buf= ...

I had set the ID pin of the mini—usb is bing high (5v), is it right?
