Homepoint comes pre-compiled in 3 different versions.
The ArduiTouch version is considered to be the "Generic" version for all ESP32 boards.
It was tested with the AZ-Delivery NodeMCU ESP32.
This version is using the following PINs:
| TYPE | PIN |
|---|---|
| TFT_CS | 5 |
| TFT_DC | 4 |
| TFT_MOSI | 23 |
| TFT_SCLK | 18 |
| TFT_RST | 22 |
| TFT_MISO | 19 |
| TFT_LED | 15 |
| TOUCH_CS | 14 |
| TOUCH_IRQ | 2 |
Some of the IL9341 Display units seem to differ in e.g. how the touch-screen coordinates correspond to the display or how the LED backlight is controlled. Therefore we offer some options to override the defaults during runtime in the configuration file.
| Key | Value |
|---|---|
| "ledPinPullup" |
true or false - control backlight power which can be pull-up/down depending on unit |
| "screenRotationAngle" | The rotation parameter can be 0, 1, 2 or 3 - incrementing in 90deg angles |
