◆ PGA_GAIN_CROSS()

void PGA_GAIN_CROSS ( uint8_t  scheda_su_scheda_giu,
uint8_t  canale,
uint8_t  PGA_gain_to_set 
)

Here the 2 digital signals from the trimmer are exploited to set the gain of the input stage of the PGA.

Parameters
[in]scheda_su_scheda_giuOne of the 2 boards that the postfrontend manages
[in]canaleThe channel for which we need to manage the trimmer
[in]PGA_gain_to_setThe overal gain to set
Returns
No Parameters
