This repository aims to document and show how to use the different peripherals. For graphical demo check also tuupola/esp_effects. Compile the kitchen sink with the following:
$ git clone [email protected]:tuupola/esp_twatch2020.git --recursive
$ cd esp_twatch2020
$ cp sdkconfig.twatch2020 sdkconfig
$ make -j8 flash
| Purpose | |
|---|---|
| DC-DC1 | PWM charger. |
| DC-DC2 | Not used 0.7V to 2.275V, 1.6A. |
| DC-DC3 | ESP32, 0.7V to 3.5V, 1.2A. Always enable! |
| LDO1 | Always on 30mA. |
| LDO2 1) | Display backlight 1.8V to 3.3V, 200mA. |
| LDO3 2) | Audio power 0.7V to 3.5V, 200mA. |
| LDO4 | Not used 1.8V to 3.3V, 200mA. |
| LDO5 | Not used 1.8V to 3.3V, 50mA. |
- Just turning LDO2 on is not enough. Must also enable PWM.
- Watch stops booting when LDO3 is enabled?
