---help---
|
|
If the board supports the standard LED interfaces as
|
|
defined in include/nuttx/board.h header file, then this
|
|
standard LED lower half driver might be usable.
|
|
|
|
In order for this generic driver to be usable:
|
|
|
|
1. The board implementation must provide the LED
|
|
interfaces as defined in include/nuttx/board.h
|
|
|
|
If your board does not meet these requirements, then the
|
|
userled_lower.c file can still be copied to your your
|
|
board src/ directory and modified for your specific board
|
|
requirements.

Extends the standard LED interface as defined in the

each LED), this selection inverts the outputs so that the

Enable support for the Worldsemi WS2812 LED driver which commonly

found in LED strips.
|
|
NOTE: Depending on the board selected, this device may require
|
|
exclusive use of an SPI bus as ws2812 LEDs have no CS or
|
|
RESET line.
|
|
|
|
# NOTE: Once the older SPI driver is migrated to the new model
|
|
# we should remove the "select SPI" in the above config.

bool "Support the new non-SPI WS2812 driver."

|
|
---help---
|
|
The original driver used SPI hardware to clock bits to the
|
|
pixels. The driver is being re-designed to support other
|
|
implementations. Selecting this option builds the new

model driver.

---help---
|
|
The number of ws2812s chained to this port. Although the

|
driver allows up to 65,535 ws2812s the practical limit will

depend on processor speed and other resources.

Some ws2812 work-alike chips have a white LED in addition
|
|
to the standard red, green, and blue LEDs. This option
|
|
enables support for such chips. Note that the driver does
|
|
not support chains with a mix of RGB and RGBW pixels.

int "WS2812 Bit Frequency (Hz)"

|
|
---help---
|
|
Frequency in Hz.
|
|
On SPI mode (WS2812_NON_SPI_DRIVER not selected), this is
|
|
the SPI frequency (commonly a few MHz) to generate the required
|
|
waveforms to represent a 0/1 symbol.
|
|
On non SPI mode (WS2812_NON_SPI_DRIVER selected), this should be set
|
|
to the bit frequency of the ws2812s being used. Newer chips use an
|
|
800 kHz bit frequency (the default); although, some older chips run
|
|
at 400 kHz.
