## Current Features
|
|
- Measure length using rotary encoder
|
|
- Wind to set length while start-button is pressed
|
|
- Automatic wire cutter
|
|
- Control interface:
|
|
- 2x 7-Segment display showing lengths and notifications
|
|
- Buzzer for acoustic notifications
|
|
- 4 Buttons and Potentiometer for setting the target length
|
|
- Reset and Cut Button
|
|
- Stepper motor controlling a linear axis guiding the cable while winding
|
|
- Store last axis position at shutdown
|

|
|
- Size: 38*35.5mm/1.49*1.39"
|
|
- Output :AB 2phase output rectangular orthogonal pulse circuit, the output for the NPN open collector output type
|
|
- Maximum mechanical speed: 5000 R / min
|
|
- Response frequency: 0-20KHz
|
|
- Cable length: 1.5 meter
|
|
- size: http://domoticx.com/wp-content/uploads/2020/05/LPD3806-afmetingen.jpg

# Installation
|
|
For this project **ESP-IDF v4.4.4** is required (with other versions it might not compile)
|
|
```bash
|
|
#download esp-idf
|
|
yay -S esp-idf #alternatively clone the esp-idf repository from github
|
|
#run installation script in installed folder
|
|
/opt/esp-idf/install.sh
|
|
```
|
|
|
|
# Build
|
|
### Set up environment
|
|
```bash
|
|
source /opt/esp-idf/export.sh
|
|
```
|
|
(run once per terminal)
|
|
|
|
### Compile
|
|
```bash
|
|
cd board_single
|
|
idf.py build
|
|
```
|
|
|
|
# Flash
|
|
- connect FTDI programmer to board (VCC to VCC; TX to RX; RX to TX)
|
|
- press REST and BOOT button
|
|
- release RESET button (keep pressing boot)
|
|
- run flash command:
|
|
```bash
|
|
idf.py flash
|
|
``` |
