A smartwatch based on ESP32 from LlyGo. Currently under development.
Clone this repository and open it with platformIO. Build and upload. On a terminal in vscode you can do it with
pio run -t uploador simple press "build and upload" in platformIO.
- the webserver crashes the ESP32 really often
- the battery indicator is not accurate, rather a problem with the power management unit ( axp202 )
- from time to time the esp32 crashes accidentally
- and some other small things
On startup you see the main screen (time tile). It show the time and the current weather (if correct configure). Now you can swipe with you fingers up, down, left and right between the four main screens. The four screens are organized in time, apps, note and setup tile. For the weather app you need an openweather.com api-id. http://openweathermap.org/appid is a good starting point.
Internal RAM is very limited, use PSRAM as much as possible. When you work with ArduinoJson, include this
#include "hardware/json_psram_allocator.h"
and create your json with
SpiRamJsonDocument doc( 1000 );
to move your json into PSRAM, here is enough RAM for all the crazy stuff you will do. And use
ps_malloc(), ps_calloc() and ps_realloc()
as often as possible. And one very important thing: Do not talk directly to the hardware!
The firmware has an integrated webserver. Over this a screenshot can be triggered. The image has the format RGB565 and can be read with gimp. From bash it look like this
wget x.x.x.x/shot ; wget x.x.x.x/screen.565
