# W800_Smart_Watch # W800_Smart_Watch
## Why this project : ## Why this project :
I was interested in working on a bigger project with more challenges and which could be useful.
I am also quite unhappy with the smartwatches that are on the market (expensive, no access to the firmware, data collection and privacy issues), that's why I decided to try doing my own that I can fully customize. This is going to be a long adventure with a lot of discoveries along the way :).
I also wanted to test this W800 SOC more deeply and see what it could do and I think it perfectly fits the project.
So let's go !

## What is done/working so far :
* LVGL 8.3.3 running on the SOC using DMA.
* Supported LCD drivers : ILI9341 with D/C pin and ST7789 with D/C pin
* Two screens designed and working with LVGL : 1 watch face based on a casio watch and a menu list with icons.
## To do :
* Write I2C drivers for the BMA456, BMP280 and HMC5883L.
* Finish to design the settings page.
* Test the charge circuit.
* Draw the schematic.
* Design the PCB.
