Enumerations
enum	I2C_to_Parallel_pin_type {   pin_1 , pin_2 , pin_3 , pin_4 ,   pin_5 , pin_6 , pin_7 , pin_8 }
	These are the aliases for the I2C to parallel output. More...

Functions
void	I2C_to_Parallel_ini_PCA9554 (uint8_t scheda_su_scheda_giu, uint8_t select_PCA)
	The I2C_to_Parallel_ini_PCA9554 inits the I2C_to_Parallel_ini_PCA9554 chips by setting all the outputs high, but the 2 chip select analog muxes, to disable all the chips.
void	I2C_to_Parallel_set_PCA9554_outputs_values (uint8_t scheda_su_scheda_giu, uint8_t select_PCA, uint8_t value)
	The function I2C_to_Parallel_set_PCA9554_outputs_values allow to set the output pin of the I2C to parallel, there are structures for this. The detector: detector_chip_select_bias, the PGA_DAC.

Variables
const struct chip_select_type	detector_chip_select_bias [6]
	This is the vector of constant values which allows to enable the relays drivers of each channels, one at a time. Every selecting pin to be enabled needs to select the chip, namely the port to which is connected, and the pin on the port.
