SSI_Status
ADwin
SSI_Status
SSI_Status
returns the current read-status on the speicified module for a
specified decoder.
Syntax
#Include
ADwinGoldII.inc / GoldIITiCo.inc
ret_val
=
SSI_Status
(
dcdr_no
)
Parameters
Notes
Use the status query only in the SSI mode "single shot". In the mode
"continuous" querying the status is not useful.

0: Decoder is ready, that is a complete value was
has been read.
1: Decoder is reading an encoder value.
