Photon is Open-Source firmware for pick and place feeders.
|
|
|
|
A feeder is a small machine that moves component tape very small, precise increments in order to automatically serve up new components to a pick and place machine.
|
|
|
|
Photon was originally developed as part of the LumenPnP project, but it is designed to support many types of hardware.

## Picking a Release
|
|
|
|
If you're looking to update to the latest stable release, use the release tagged `Latest`. Do NOT use a `Pre-Release` firmware, or one with `rc` in the name. We release lots of Release Candidate (denoted with an `rc` in the version name) firmware builds that are still being tested. If you're interested in testing the latest build, then the `rc` fimware is for you!

|
## Building and uploading
|
|
|
|
We use [platformio] for building, testing, and uploading this firmware. Refer to their docs for basic instructions on using platfomio.
|
|
|
|
The default `pio` environment is intended for use with a [Black Magic Probe][bmp] for uploading a debugging:
|
|
|
|
```sh
|
|
pio run
|
|
```
|
|
|
|
However, if you just want to program the feeder over UART, such as with the FTDI USB UART bridge included with the LumenPnP, you can use:
|
|
|
|
```sh
|
|
pio run -e photon-serial -t upload --upload-port /dev/tty...
|
|
```
