# rp2040_ndsp

> rp2040_ndsp.py is a stripped-down, simple NDSP server which runs on an RP2040 embedded processor

## Article

The RP2040 is like a miniature Raspberry PI, and it is used to run [Adafruit's CircuitPython](https://learn.adafruit.com/welcome-to-circuitpython/what-is-circuitpython), with the [Wiznet5k Ethernet library](https://learn.adafruit.com/ethernet-for-circuitpython). This setup offers 29 multifunction GPIO pins (including four ADC channels) for control by an NDSP:

This NDSP server can be called from ARTIQ; see [`rp2040_experiment.py`](https://github.com/ichuang/rp2040_ndsp/blob/main/rp2040_experiment.py) for example. A convenient way to test this is using the [dartiq](https://github.com/Technosystem-Labs/dartiq) dockerized ARTIQ package. Install that package, enter this into `device_db.py`:

```plaintext
device_db = {
    # rp2040 nano NDSP
    "rp2040": {
	"type": "controller",
        "host": "192.168.1.221",
        "port": 3476,
    },
}
```

then run:

```plaintext
    dartiq run "artiq_run ./rp2040_experiment.py"
```

and you should see:

```plaintext
ping =  Example NDSP is alive!
add result =  18
```
