# nRF52840 DK I<sup>2</sup>C Scanner
Quick and simple program to scan for used I<sup>2</sup>C addresses on an
(nRF52840
DK)[https://www.nordicsemi.com/Products/Development-hardware/nRF52840-DK].
# Setup
Connect I<sup>2</sup>C as follows:
```
GND -> GND
VCC -> VDD
SDA -> P0.03
SCL -> P0.04
```
## Software
Either use [nix](https://nixos.org/download/) and enter the dev shell with
`nix develop` or ensure that at least the following is installed:
- [rust](https://www.rust-lang.org/learn/get-started)
- [probe-rs](https://probe.rs/)
Attach the dev-kit with USB, turn it on and run `probe-rs list` to verify the
connection. It should show something akin to the following:
```
The following debug probes were found:
[0]: J-Link (J-Link) (VID: 1366, PID: 1051, Serial: 001050288663, JLink)
```
Run `cargo run` to compile the software and flash it. The resulting output will
tell you at which addresses I<sup>2</sup>C devices were found.
_Example output with a device at 0x27_
```
0.014221 INFO i2c device at 0x27
```
