See CanBus
The [CAN Dash] was originally manufactured with STM32 microcontroller.
The 25pin version is more featureful, with
- more IO-s. HW has
- 20+ analog inputs
- temperature measurements
- multiple frequency/speed inputs
- and capable of input capacitive measurements for activation input buttons/switches
Firmware utilizes some of these, with more possibilities in the future.
See CanBus, 3 different firmware versions:
- BMW
- VAG (Audi)
- AIM see AimCanBusMessages (most data of these 3 versions)
Uploading a different version (normally NOT necessary, if ordered with the desired version) takes only a few seconds.
