This is NO-NAV version. Here is no navigation system, but other features are present (I guess)!
LVGL-BIKE (not final project name) is a project that replicates bike computers with nice interface by lvgl and endless modifications and improvments by esp32.
- Esp32 (no matter which devkit, I am using DOIT)
- Ili9341 display 320x240 WITH TOUCH (it is mandatory for now because there is no support for button controls)
- Any light controlled by a relay
- Hall sensor, for example KY-003
Let's start with the display (ILI9341):
| Display pin | ESP32 pin |
|---|---|
| T_IRQ | Not connected |
| T_D0 | D19 |
| T_DIN | D23 |
| T_CS | D21 |
| T_CLK | D18 |
| SD0 (MISO) | Not Connected |
| LED | 3v3 |
| SCK | D18 |
| SDI (MOSI) | D23 |
| DC | D2 |
| RESET | D4 |
| CS | D15 |
| GND | GND |
| VCC | 3v3 |
Then, the first light:
| Relay pin | ESP32 pin |
|---|---|
| + | Vin (5v) |
| - | GND |
| S (signal) | D13 |
And finally the hall sensor:
| Sensor pin | ESP32 pin |
|---|---|
| + | 3v3 |
| - | GND |
| S (signal) | D12 |
In future there will be battery control, maybe navigation and bluetooth/mp3 playing.
