Detailed Description

Enumeration Type Documentation

Status of the NeoPixel data transfer.

Enumerator
TRANSFER_STATUS_IDLE	No active transfer.
TRANSFER_STATUS_WORKING	A transfer is currently active.

Copies a color to the specified index of the frame buffer.

Parameters

	index	The index to write.
[in]	p_color	Pointer to the color to copy.

volatile color_rgb_t * npdata_frame_buffer_get ( void )

Gets a pointer to the frame buffer.

Warning: Do not write to the frame buffer while npdata_status_get() returns TRANSFER_STATUS_WORKING.

transfer_status_t npdata_status_get ( void )

Gets the current status of the NeoPixel data transfer.

Return values

TRANSFER_STATUS_IDLE	No transfers are active.
TRANSFER_STATUS_WORKING	Data is currently being transferred.
