instruction_for_PGA_GAIN_set()

void instruction_for_PGA_GAIN_set

(

void

)

The second stage gain is settable here.

This instruction needs to know the gain to set and the channel to apply the setting. These informztion are at byte istruzione_byte_4_e_scelta_canale and at bytes byte_istr_dati_0 and byte_istr_dati_1 of the CAN message.

Returns

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

    //This function must be optimized as it must opetrate with the x1 / x10 pre pga gain
    //vettore_istruzioni[1]=0 means channel 0, vettore_istruzioni[1]>0 means channel 1
    // vettore_istruzioni[2] is the MS8bits, while vettore_istruzioni[3] are the LS8bits 
    //of the gain to set.
