Macros
#define	fondo_scala_DAC_PGA   (uint32_t) 0x3FF /*(1<<10)-1*/
#define	PGA_set_pre_pga_high_gain   0x02
	Set the amplifier gain in front of the PGA to 10 V/V, it is left shifted once in the trimmer.
#define	PGA_set_pre_pga_low_gain   0x01
	Set the amplifier gain in front of the PGA to 1 V/V, it is left shifted once in the trimmer.
#define	set_pre_pga_idle   0
	The swirches are set both off.
#define	gain_pre_PGA_x_2   guadagno_minimo_PGA *10
#define	PGA_pre_PGA_max_gain   10

Functions
void	PGA_set_reset_pre_PGA_gain (uint8_t scheda_su_scheda_giu, uint8_t canale, uint8_t set_1_reset_0)
	Here the 2 digital signals from the trimmer are exploited to set the gain of the input stage of the PGA.
void	PGA_GAIN (uint8_t scheda_su_scheda_giu, uint8_t canale, uint8_t guadagno_da_impostare)
	It sets the PGA gain irrespective of the offset.
void	PGA_DAC_GAIN_CROSS (uint8_t scheda_su_scheda_giu, uint8_t canale, uint8_t guadagno_da_impostare, uint8_t PGA_si_NO)
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.
void	PGA_GAIN_set (char canale, unsigned int guadagno_da_impostare)
	It sets the new gain irrespective of the offset.
void	PGA_preparation_to_gain_set (char canale, unsigned int guadagno_da_impostare)
	It sets the new gain letting the output offset at the same level.
