# Igloo64SAME51Blinky #

Firmware for Atmel/Microchip ATSAME51J20A microcontroller (ARM) on Igloo64 prototyping board.

The board has nine big LEDs, and this code blinks them.

It also generates an analog staircase waveform on the 12-bit DAC,

VOUT0.

| D4     |     51      | PA27 |

| D5     |     50      | PB23 |

| D6     |     46      | PA25 |

| D7     |     41      | PA20 |

| D8     |     37      | PA18 |

| D9     |     32      | PA15 |

| VOUT0  |     3       | PA02 |

| VOUT1  |     14      | PA05 |

| AIN6   |     15      | PA06 |

| AIN7   |     16      | PA07 |

| TxD    |     17      | PA08 |

| RxD    |     18      | PA09 |

GPIO pin assignments are by physical proximity on the PCB.

ADC pin assignments attempt to avoid clashes with SERCOM pins.
