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.
