This repository provides the hardware and software components of a CAN Interface Add-On for the Glasgow Digital Interface Explorer.
A rough spec is outlined below:
- Sits alongside a Glasgow board
- 2x CAN interfaces, available on a single port
- Standard DE-9 connectors
- Default pinout is suitable for use with existing CAN and OBD-II adapter cables (on CAN1 and CAN2 repsectively)
- Can be easily rewired by cutting jumpers
- Spring-loaded terminal blocks for ease-of-use
- Indicator LEDs for Tx and Rx
- Software configurable 120Ω termination, with state LED
- ESD protection
- CAN FD support in hardware (software to follow)
Future plans:
- Isolation between each CAN port and the Glasgow (and host)
Out-of-Tree support will be required when work on the applet begins (see PR #213).
