Peripheral basics
Inkplate 6 MOTION has some useful peripherals, including sensors, LEDs and user inputs. They are all integrated in the Inkplate MOTION library. This page contains a quick overview of functions which are in common with all peripherals.
Powering on
⚠️
To use any peripheral, it needs to be powered on. This is important, as trying to communicate with a peripheral which wasn't powered on before results faliure to initialize.
To power on any peripheral, use peripheralState:
inkplate.peripheralState(INKPLATE_PERIPHERAL_APDS9960, true);
inkplate.peripheralState()
Enables or disables Inkplate 6 Motion peripherals to save power during sleep.
Returns: none
Function parameters:
| Type | Name | Description |
|---|---|---|
uint8_t | _peripheral | Selected peripheral (e.g., INKPLATE_PERIPHERAL_SDRAM, INKPLATE_PERIPHERAL_ROTARY_ENCODER). See below for the full list. |
bool | _en | Set the state of the selected peripheral; true enables it (power on), false disables it (power off). |
| Peripheral Name | Description | Bit Mask Value |
|---|---|---|
INKPLATE_PERIPHERAL_SDRAM | External SDRAM used for framebuffer storage. | 1ULL << 0 |
INKPLATE_PERIPHERAL_ROTARY_ENCODER | Rotary encoder for user input. | 1ULL << 1 |
INKPLATE_PERIPHERAL_WS_LED | WS2812 LED for status indication. | 1ULL << 2 |
INKPLATE_PERIPHERAL_SHTC3 | SHTC3 temperature and humidity sensor. | 1ULL << 3 |
INKPLATE_PERIPHERAL_APDS9960 | APDS9960 gesture and proximity sensor. | 1ULL << 4 |
INKPLATE_PERIPHERAL_LSM6DSO32 | LSM6DSO32 accelerometer and gyroscope. | 1ULL << 5 |
INKPLATE_PERIPHERAL_MICROSD | microSD card slot for external storage. | 1ULL << 6 |
INKPLATE_PERIPHERAL_WIFI | Wi-Fi module for wireless connectivity. | 1ULL << 7 |
INKPLATE_PERIPHERAL_ALL_PERI | Includes all peripherals except SDRAM & Wi-Fi. | Combination of above bit masks |
INKPLATE_PERIPHERAL_ALL | Enables all peripherals including SDRAM & Wi-Fi. | Combination of all bit masks |
Powering off
In a similar way, if you want to save power, you can use peripheralState to turn all (or individual) peripherals off:
inkplate.peripheralState(INKPLATE_PERIPHERAL_ALL, false);
