instruction_Detector_PGA_Rele()

void instruction_Detector_PGA_Rele

(

void

)

This is a sub-function of the ADC instrunction. It is useful as it cane be used in other part of the program such as detector bias setting and offset adjustement.

Parameters

[in]

sottoistruzione

is the selctring node according to the list at ADC_Mux_page

Returns

No Parameters, the actual result is sent to the CAN bus output throught tx_data.

// int lettura_ADC( char sottoistruzione){
//   char ii;
////     ATTIVA_CHIP_SELECTOR_MULTIPLEXER( (sottoistruzione >> 4) & 0x7); //the 4 MSb select the mux
////     Line_select_in_the_mux(  sottoistruzione & 0xF); //The 4 LSb select te mux line
//   Aspetta_tanti_ms(wait_for_ADC_setting); //Wait for nodes stabilization
//  risultato=0;
//   for( ii=0; ii <(1 <<  medie_ADC); ii++){    
//   risultato += ADC_lettura_24bit(0,0,2); //Measurement is taken
//   }
//   risultato=risultato>>medie_ADC;
 
////     Stampa_risultato_sul_CAN(risultato); //The result is composed in the CAN message, 4 MSB.
////     ATTIVA_CHIP_SELECTOR_MULTIPLEXER( 0);  //Disable all mux's
//   return risultato;   
// }

We manage the relais which take care of the deetector performances. The relay for the pre PGA gain x1 - x10 is managed here, too.

This instruction needs to know the gain to set and the channel to apply the setting. These informztion is at byte istruzione_byte_4_e_scelta_canale of the CAN message.

Returns

No Parameters, the actual result is sent to the CAN bus output throught tx_data.
