Generalities

Microcontroller: Atmega328p
ADC: MCP3208

ADC

ADC is accessed using standard SPI port on Atmega328p using pins MISO MOSI SCK.

Chip select differs according to board type slave or master.


Board Type	Atmel Pin	Arduino Pin
Master	PB2	10
Slave 1	PD6	6
Slave 2	PD7	7
Slave 3	PB0	8
Slave 4	PB1	9

ADC bits: 12
ADC Reference: 3300mV

Serial Port

Standard UART is used on Atmega328.

PD0 (Arduino Pin 0) is RXD.
PD1 (Arduino Pin 1) is TXD.
