Terasic DE10-Nano

The DE10-Nano Development Kit presents a robust hardware design platform built around the Intel System-on-Chip (SoC) FPGA, which combines the latest dual-core Cortex-A9 embedded cores with industry-leading programmable logic for ultimate design flexibility. Users can now leverage the power of tremendous re-configurability paired with a high-performance, low-power processor system. Altera’s SoC integrates an ARM-based hard processor system (HPS) consisting of processor, peripherals and memory interfaces tied seamlessly with the FPGA fabric using a high-bandwidth interconnect backbone. The DE10-Nano development board is equipped with high-speed DDR3 memory, analog to digital capabilities, Ethernet networking, and much more that promise many exciting applications.

Board Support

Protocol Notes

No muxes available for multi-function pins yet (e.g. you won't be able to use D0 & D1 on Arduino header as GPIOs).

Switches, Buttons, LEDs

These are already in use by kernel drivers with the default image, except for KEY0 and KEY1. To use them with MRAA remove them from the device tree.

To enable the switches temporarily (until reboot):

```sh echo ff204000.gpio >/sys/bus/platform/drivers/altera_gpio/unbind echo ff204000.gpio >/sys/bus/platform/drivers/altera_gpio/bind ```

And for LEDs:

```sh echo ff203000.gpio >/sys/bus/platform/drivers/altera_gpio/unbind echo ff203000.gpio >/sys/bus/platform/drivers/altera_gpio/bind ```

Built-in ADXL345

Exposed on I2C bus 0. To use you will have to unbind the device driver first:

```sh echo 0-0053 > /sys/bus/i2c/drivers/adxl34x/unbind ```
