RUN_MODE

Normal control loop to have the light in accordance with the gv_lamp_preset_current

variable that is permanently updated in the command control state machine in the

Main_pwmx_fluo_demo.c file.

The transition from the RUN_MODE state to the LAMP_OFF state is done in the ADC

state machine during the V_LAMP_CONV or I_LAMP_CONV state in the case the

gv_request_lamp _off has been set by the comm and control task in th e

Main_pwmx_fluo_demo.c file.

TOO_MANY_LAMP_IGNITION_TRIES

If the ignition has failed LAMP_IGNITION_MAX_TRIES, a lamp switch off is requested

by setting the gv_request_lamp_off and the LAMP_OFF state takes effect during the

next I_LAMP_CONV or the V_LAMP_CONV state of the ADC state machine in the

Main_pwmx_fluo_demo.c file.

NO_LAMP

If no lamp is detected during the LAMP_NUMBER_CHECK, a lamp off is requested by

setting the gv_request_lamp_off and the effective return to the LAMP_OFF state takes

place during the next I_LAMP_CONV or the V_LAMP_CONV state of the ADC state

machine in the Main_pwmx_fluo_demo.c file.

Lamp state machine

Global variables

6.3.2.1

Input variables

which have an

impact on the Lamp

state machine

•

The transition from LAMP_OFF to PFC_CONTROL_LOOP is done when the

gv_pfc_state is set to PFC_CONTROL_LOOP in Pfc_ctrl.c file.

• The transition from the RUN_MODE state to the LAMP_OFF state is done in

the ADC machine during the V_LAMP_CONV or I_LAMP_CONV state in the

case gv_request_lamp_off has been set by the command control task in the

Main_pwmx_fluo_demo.c file.

6.3.2.2

Output variables

which can impact

other state machine

•A lamp off (gv_request_lamp_off == 1 ) can be set by the lamp fault mode. The effect

of this request takes place in the I_LAMP_CONV or V_LAMP_CONV in the ADC

state machine in the Main_pwmx_fluo_demo.c file.
