[[File:2018-09-25 153651.png|thumbnail| CAN UCCB Commands]]
==== UCCB examples ====
<source lang="c">
000005: C (send close command)
000006: v (ask for firmware version)
000007: v0102 (get version number from device)
000008: V (ask for hardware version)
000009: V0101
000010: N
000011: N16000000
000012: W2D00
000013:
000014: S8 (set speed to 1000000 b/s)
000015:
000016: O (open CAN for frame transmission and reception)
000017:
000018: t00181122334455667788 (transmit frame type standard id = 1 length 8 bytes)
000019: z
000020: t0890
000021: M00007000000010000000010 (set id filter for ID=1 and ID=1)
</source>

data command: t00181122334455667788 = t / 001 / 8 / 11 22 33 44 55 66 77 88
* 001 is identifier, length = 8bytes

== Linux | RPI ==
config SPI CAN: edit in file /boot/config.txt, and add following line
dtparam=spi=on
dtoverlay=mcp2515-can0,oscillator=12000000,interrupt=25,spimaxfrequency=2000000
Reboot and check if installed: dmesg | grep -i '\(can\|spi\)'
[ 3.443582] CAN device driver interface
[ 3.469391] mcp251x spi0.0 can0: MCP2515 successfully initialized.

=== Python ===
* first install library sudo pip install python-can
msg = bus.recv(10.0) #timeout 10 seconds
* Test send from USB CAN C = close port, S3 = set to 100K speed, O = open port, t00181122334455667788 = send data

* Test receive: root@work:/home/pi/rpi/interface/CAN/python# python receive.py
Timestamp: 1576078751.049400 ID: 0001 S DLC: 8 11 22 33 44 55 66 77 88 Channel: can0

* Bitrate - 100000 (100K S3), 1000 000(1M S8)
