# The PIXO Pixel
PIXO Pixel is a 16 x 16 RGB LED display that runs off of an ESP32.
This project is open source!
You can find the Bill of Materials [here](https://www.findchips.com/org/10-open-hardware/list/85998-pixo-pixel-esp-board-and-led-board) on FindChips.
If you want to build this yourself, you can find the Bill of Materials [here](https://www.findchips.com/org/10-open-hardware/list/85998-pixo-pixel-esp-board-and-led-board) on FindChips.
I have submitted a pull request to the Arduino-ESP32 github: https://github.com/espressif/arduino-esp32 to have the PIXO Pixel have its own board file. This will ensure the pinout that was used will match the pin declartion on the board. In the meantime, please use the "Adafruit Feather ESP32" in the board manager, as the pinout is the same.

3. Various other libraries are required for the example firmware; they are listed below under "Libraries used in Example Firmware"
4. Connect your pixo pixel to your computer and start Arduino
5. Under the "Tools" menu, select "Board->Adafruit ESP32 Feather"; Leave Flash frequency and Upload speed the default
6. Under Port, select your pixo

7. Compile and upload
8. When the Arduino console says "Connecting....", press and release both the boot and reset buttons simultaniously
8. When the Arduino console says "Connecting....", press and hold both the boot and reset buttons simultaniously for 1 second; then release both buttons
9. You should start to see output about flashing
10. When the flash is complete, press the reset button on the pixo to start your new firmware

### Patching I2Cdev and MPU6050 Libraries
1. Download i2cdevlib and extract the zip file
2. Inside the i2cdevlib/Arduino, copy `I2Cdev` and `MPU6050` folders to your `libraries` folder
3. Edit `I2Cdev/I2Cdev.cpp`, and immedietly under `#include "I2Cdev.h"`, add the following

```
#ifdef ARDUINO_ARCH_ESP32
#define BUFFER_LENGTH I2C_BUFFER_LENGTH
#endif
```
