Description

Fits the BMW E39 Instrument cluster

Designed for my electric car conversion so not stand-alone and requires the other modules to get the car to work as you know BMW computers do not work very well when you disconnect the ECU and security.

With fixes and enhancements from previous version

  1. Serial changed to CAN bus
  2. LCD Footprint fixed
  3. Better Switch mode supply
  4. number of multiplexed segments halved to 16 from 32 (still too many but works ok)

Looks to be OK, built and tested and all LEDs work. Base pic33k test code attached which will light all LEDs using a 100uS multiplexing interrupt, but no code for the LCD or CAN yet so this part is still untested and I need to get the other boards working before I go there...
