Hi! I'm looking for an open platform which supports Codesys V3 and provides "raw" CAN access on at least 2 CAN interfaces. The BeagleBone Black apparently has 2 CAN interfaces, but is it possible to use both with capes such as https://www.waveshare.com/wiki/RS485_CAN_CAPE? Is it possible to simply attach two of them?
If possible, I would also like to have 1 x RS232 and 1 x RS422. Any suitable capes available? The Waveshare cape apparently only supports two wire RS485.
Br,
Peter
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Hello! This is possible. At the same time, the second can is dcan0 and it falls on the i2c2 pins.
Solution: 1) create a device tree overlay for dcan0
2) disable the i2c2 bus in the main device tree.
