SSI_Set_Bits
SSI_Set_Bits
sets for an SSI counter the amount of bits which generate a
complete encoder value.
The number of bits should be equal to the resolution of the encoder.
Syntax
#Include
ADwinGoldII.inc / GoldIITiCo.inc
SSI_Set_Bits
(
dcdr_no
,
bit_no
)
Parameters
Notes
The resolution (amount of bits) of the SSI encoder should be similar to
the amount of bits which are transferred.
