Holtek ht16k33 RAM mapping 16*8 LED controller driver with keyscan
|
|
-------------------------------------------------------------------------------
|
|
|
|
Required properties:
|
|
- compatible: "holtek,ht16k33"
|
|
- reg: I2C slave address of the chip.
|
|
- interrupt-parent: A phandle pointing to the interrupt controller
|
|
serving the interrupt for this chip.
|
|
- interrupts: Interrupt specification for the key pressed interrupt.
|
|
- refresh-rate-hz: Display update interval in HZ.
|
|
- debounce-delay-ms: Debouncing interval time in milliseconds.
|
|
- linux,keymap: The keymap for keys as described in the binding
|
|
document (devicetree/bindings/input/matrix-keymap.txt).
|
|
|
|
Optional properties:
|
|
- linux,no-autorepeat: Disable keyrepeat.
|
|
- default-brightness-level: Initial brightness level [0-15] (default: 15).
|
|
|
|
Example:
|
|
|
|
&i2c1 {
