nrf51-neopixel

This is a library for using WS2812(B) NeoPixels with a Nordic Semiconductor NRF51822 Bluetooth Low Energy ARM SoC.

Developed by Lava, LLC.

##Example code:##

neopixel_strip_t m_strip;
uint8_t dig_pin_num = 6;
uint8_t leds_per_strip = 24;
uint8_t error;
uint8_t led_to_enable = 10;
uint8_t red = 255;
uint8_t green = 0;
uint8_t blue = 159;

neopixel_init(&m_strip, dig_pin_num, leds_per_strip);
neopixel_clear(&m_strip);
error = neopixel_set_color_and_show(&m_strip, led_to_enable, red, green, blue);
if (error) {
	//led_to_enable was not within number leds_per_strip
}
//clear and remove strip
neopixel_clear(&m_strip);
neopixel_destroy(&m_strip);

##For use with Nordic S110 SoftDevice:##

Include in main.c

#include "ble_radio_notification.h"

Setup the radio notification with a callback handler(see nrf_soc.h: NRF_RADIO_NOTIFICATION_DISTANCES and NRF_APP_PRIORITIES)

ble_radio_notification_init(NRF_APP_PRIORITY_xxx,
							NRF_RADIO_NOTIFICATION_DISTANCE_xxx,
							your_radio_callback_handler);

Create the callback handler

void your_radio_callback_handler(bool radio_active)
{
	if (radio_active == false)
	{
		neopixel_show(&strip1);
		neopixel_show(&strip2);
		//...etc
	}
}

Write to LEDs

uint8_t neopixel_set_color(...);

Do NOT use neopixel_set_color_and_show(...) with BLE. The LEDs should only be written to in the radio notification callback.
