EDT_TIMEOUT_NULL no extra action taken

EDT_TIMEOUT_BIT_STROBE flush any valid bits left in input circuits of

SSDIO.

Return

No return value.

edt_get_timeout_goodbits

Description

Returns the number of good bits in the last long word of a read buffer after the last timeout. This

routine is called after a timeout, if the timeout action is set to EDT_TIMEOUT_BIT_STROBE. (See

edt_set_timeout_action on page 32.)

Syntax

#include "edtinc.h"

int edt_get_timeout_goodbits(EdtDev *edt_p);

Arguments

edt_p device handle returned from edt_open or edt_open_channel

Return

Number 0–31 represents the number of good bits in the last 32-bit word of the read buffer associated

with the last timeout.

edt_do_timeout

Description

Causes the driver to perform the same actions as it would on a timeout (causing partially filled fifos to

be flushed and dma to be aborted). Used when the application has knowledge that no more data will be

sent/accepted. Used when a common timeout cannot be known, such as when acquiring data from a

telescope ccd array where the amount of data sent depends on unknown future celestial events. Also

used by the library when the operating system can not otherwise wait for an interrupt and timeout at the

same time.

Syntax

int edt_do_timeout(EdtDev *edt_p)

Arguments

edt_p device struct returned from edt_open

Example

edt_do_timeout(edt_p);

Return

0 on success, -1 on failure
