| Storage | MicroSD |
| Linux kernel | 4.9 w/ Raspberry Pi patches |
| IEx terminal | ttyS0 |
| GPIO, I2C, SPI | Yes - Elixir ALE |
| ADC | No |
| PWM | Yes, but no Elixir support |
| UART | 1 available - ttyS0 |
| Camera | Yes - via rpi-userland |
| Ethernet | Yes |
| WiFi | Yes - Nerves.InterimWiFi |
| Bluetooth | Not yet |
The most common way of using this Nerves System is create a project with mix nerves.new and to export MIX_TARGET=rpi3.
Then, change the rpi3 system dependency to
{:kiosk_system_rpi3, "~> 1.0"}
See the Getting started guide for more information.
If you need custom modifications to this system for your device, clone this repository and update as described in Making custom systems
See the example project for more info
Building this image require running under docker. If you are compiling locally, your instance of docker will need to have at least 8gb of ram assigned to it.
WiFi modules almost always require proprietary firmware to be loaded for them to work. The
Linux kernel handles this and firmware blobs are maintained in the
linux-firmware project. The firmware for the built-in WiFi module on the RPi3
hasn't made it to the linux-firmware project nor Buildroot, so it is included
here in a rootfs-additions overlay directory. The original firmware files came from
https://github.com/RPi-Distro/firmware-nonfree/blob/master/brcm80211/brcm.
