NXP PCA9685 16-channel 12-bit PWM LED controller
|
|
================================================
|
|
|
|
Required properties:
|
|
- compatible: "nxp,pca9685-pwm"
|
|
- #pwm-cells: Should be 2. See pwm.yaml in this directory for a description of
|
|
the cells format.
|
|
The index 16 is the ALLCALL channel, that sets all PWM channels at the same
|
|
time.
|
|
|
|
Optional properties:
|
|
- invert (bool): boolean to enable inverted logic
|
|
- open-drain (bool): boolean to configure outputs with open-drain structure;
|
|
if omitted use totem-pole structure
|
|
|
|
Example:
|
|
|
|
For LEDs that are directly connected to the PCA, the following setting is
|
|
applicable:
|
|
|
|
pca: pca@41 {
|
|
compatible = "nxp,pca9685-pwm";
|
|
#pwm-cells = <2>;
|
|
reg = <0x41>;
|
|
invert;
|
|
open-drain;
|
|
};
