# Wireless ADXL for Klipper

## This is the public release of my wireless ADXL project developed for Klipper resonance testing. I originally built this as a commercial product but due to budget restrictions I could not move it into production. Instead of shelving it, I decided to release everything here so the community can benefit from it.
The full projects source is now fully available. Hardware, firmware and host-side tools are included.

## If you find the project useful and want to support future work, you can donate here:

- Go to wadxl.local (if that doesn't work, find it's ip in your router) you should see the ota page, that's where you can update it.

### Klipper setup:

- Run this command
```wget -qO- https://raw.githubusercontent.com/Pole-Engineering/Wireless-ADXL/main/software/install_wadxl.sh | bash```
- Klipper config:
```
[wadxl]
ip = optional, entering the ip manually is better

[resonance_tester]
probe_points = 117.5,117.5, 10
accel_chip = wadxl
accel_per_hz = 160
min_freq = 20
max_freq = 120
```
### What does various patterns of LEDs mean

**RED on GREEN off:**
-Faulty ADXL or Error
**RED off GREEN on:**
-Standby mode
**RED blinking GREEN off:**
-Low voltage, charge 
**RED off GREEN blinking:**
-Sampling in progress
**RED blinking GREEN blinking:**
