Hardware Validation - Rev 1

	Validation Steps	Status	Blockers
Outputs	Verify Operation of Load switches using bts_load_switch driver Adhiraj Singh Verify Operation of Outputs using Output Config Adhiraj Singh Verify current readings Verify multiplexor with current readings Trigger Undervoltage/overvoltage conditions, see if it triggers interrupt (do after everything else in case board explodes)	IN PROGRESS
Output Read verification	Verify Outputs are successfully read in main loop	BLOCKED	Need gpio expanders verified
Lights FSM verification	Verify by setting can messages internally Verify by sending can messages over PEAK CAN	BLOCKED	Need all previous verified
Power FSM Verification	Verify by setting can messages internally Verify by sending can messages over PEAK CAN	BLOCKED	Need all previous verified

	Validation Steps	Status	Blockers
IO expander	Verify PCA expanders are able to communicate with STM PCA 1 (0x24) PCA 2 (0x26)
Outputs	Verify outputs all enable/disable as expected SOLAR_SENSE_1 SOLAR_SENSE_2 PEDAL STEERING LEFT_TURN RIGHT_TURN DRL_LIGHT BRAKE_LIGHT CENTER_CONSOLE BMS_DCDC MCI BPS_LIGHT SPARE_12V_1 SPARE_12V_2 BMS_AUX DRIVER_FAN REAR_CAM_LCD SPARE_5V_DCDC TELEMETRY SPARE_5V_AUX
Output isense read	Verify Mux select allows for output current values to be read: SOLAR_SENSE_1 SOLAR_SENSE_2 PEDAL STEERING LEFT_TURN RIGHT_TURN DRL_LIGHT BRAKE_LIGHT CENTER_CONSOLE BMS_DCDC MCI BPS_LIGHT SPARE_12V_1 SPARE_12V_2 BMS_AUX DRIVER_FAN REAR_CAM_LCD SPARE_5V_DCDC TELEMETRY SPARE_5V_AUX
AUX Valid pins	Ensure AUX valid low when no AUX supply connected AUX_VALID_1 AUX_VALID_2 Ensure AUX Valid high when aux is connected AUX_VALID_1 AUX_VALID_2
