Martin ROGER / VXDash - History

PCB layout in progress

Changed some pin assignments to aid routing.

Emulator board refinements

- Is there stupid with the Active Hi Optos so that the logic is not inverted ?
- Added N-Mosfet activatable resistors. Stupidly simple ? Better MOSFET recommendation ?

More changes (Primarily Remote ECU)

- Emulator board project to a functional skeleton
- Connectors board with ignition routing on CAN pin 4 to have switched signal available in the harness.
- Remote ECU : added 12V reduced protection circuit (to be reviewed)
- Remote ECU : Removed integrated CAN termination (should be on harness)
- Remote ECU : added CAN passthrough
- Remote ECU : added MCPWM channels
- Remote ECU : Added some opto inputs
- Remote ECU : Added internal USB C (overkill ?)

Removing external 5V and replacing with 12VBatt

For the sake of running 4 wires to the back that have +12V/CANH/CANL/GND

Minor changes

- Connection for the caliber selection on the sensing circuit
- Typo

Grape shot additions

- Added 0R to the VCC pin on the CAN transceiver for pin compatibility with other transceiver
- Updated TODO box
- Rename ADC_SDA and ADC_SCL to SDA and SCL
- Official symbol and footprint from ESP, using ESP32-S3-WROOM-1-N16R8
- Reassigned Coolant LOW to active HI
- Replaced MUX with i²C TCA9555 IO Expander
- Resequenced Active His and Lows to match current SW definition
- Resequenced ADC channels to match current SW definition
- Added simple peripherals for MCU
- Added RESET and BOOT buttons circuits
- Added CAN transceivers for each display, and Termination resistor
- Added USB C

SymLink to the LIB folder

Adding a symbolic link to the Lib folder like such :

${VXDASH_LIB}/footprints/VXDash_inductors.pretty

Minor updates

- Coolant LOW actually tests as an Active Hi
- ReadME file nuked
- Minor updates

2 new projects. VXDash Connectors and VXDash RemoteECU
