Functions
void	instr_detector_Vbias_we_want_to_set_function (void)
void	instr_Vbias_to_be_set_function (void)
	The detector bias will be set at the value set with the function instr_detector_Vbias_we_want_to_set_function() with which the target values are stored in the vector Detector_bias_target[].
static void	misura_il_valore_trimmer_detector (EPROM_detector__ *EPROM_detector, uint8_t scheda_su_scheda_giu_, uint8_t canali_da_regolare, uint8_t trimmer_da_scrivere)
static void	Detector_aggiusta_offset_SAR (EPROM_detector__ *EPROM_detector_sar, uint8_t scheda_su_scheda_giu_)
	This function provide the output offset with the fast SAR method: only a few LS bits are left for this.
void	instr_detector_scrittura_lettura_trimmer_bias_function (void)
	This is an instruction via CAN bus to read/write the detector trimmers. It calls the detector_scrittura_lettura_trimmer_bias(). A copy of the trimmers values is in the array contenuto_trimmer_detector[][].
void	instr_Relays_driver_set_reset_channel_function (void)
	Function to set the relais for detector bias.
static bool	Detector_verifica_Vbias (uint8_t scheda_su_giu, bool si_commuta)
	Function to verify if the Vbias voltage is within the limit to be swtitched.
void	instruction_Vbias_target (void)
	The detector bias will be set at the value passed from the CAN if, after this setting, it is launched instruction_Detector_bias().
void	instruction_Detector_bias (void)
	The detector bias is set at the value passed from the CAN.
void	imposta_il_trimmer_del_bias (int16_t *Valori_per_i_trimmer, long int discrepanza, int trimmer_bias_coarse_step_singolo, int trimmer_bias_fine_step_singolo)
	Trimmer settings for the function instruction_Detector_bias()
