+The conversion results of channels 9 and 10 are sent on the UART0 serial line
+(115200 8n1) at regular intervals.
+
+Each line displays the decimal and hexadecimal value of the raw conversion

+
+This example shows the support of the WS2812 chainable leds.
+It has been tested using a 60 leds strip from Adafruit.
+
+WS2812 external driver development is based on data found in the WS2812.pdf
+datasheet provided by Adafruit : https://www.adafruit.com/datasheets/WS2812.pdf
+
+
+The external driver (extdrv/ws2812.[ch]) provides an internal buffer which size
+is defined in extdrv/ws2812.h (NB_LEDS)
+This buffer is filled using ws2812_set_pixel(), and the led values are sent to
+the led strip using ws2812_send_frame().
+
+
+Leds data is generated by the filling functions from ADC samples.
