sdspi_WriteContinue

int sdspi_WriteContinue( sd_device * sd );

Description

This function completes the previously started write command to the SD card when non-blocking mode is enabled. It looks for the end of the busy signal from the card, then strobes the chip select. This function should be called repeatedly until the -EBUSY code is not returned, at which point the SPI port is freed. There is a timeout mechanism for the busy signal. If exceeded, the port is freed and the -EIO error code is returned.

Parameters

sd

The device structure for the SD card.

Return Value

0: Success
-EIO: I/O error or timeout
-EBUSY: SD card is busy with write operation; call sdspi_WriteContinue() again

Library
