Input and Output

s16a_set_dac_control_reg

Description

Write a specified value to the output DAC Control register.

Syntax

int s16a_set_dac_control_reg(S16aDev *s16a_p, int value);

Arguments
s16a_p	S16A device handle returned from s16a_open
value	Value to write to the DAC Control register.

Return

Returns 0 on success or –1 on failure. Fails if s16a_p does not refer to an output channel. Sets errno on failure.

s16a_set_defaults

Description

Resets the S16A configuration to its default state:

•The Xilinx Programming registers are set to S16A_XRESET and then cleared.

•The UART Command/Status register and the DAC Output Control register are set to 0.

•Gain and offset values are set from /dev/s16a.cfg, which is generated when you run s16acalibrate.

•Ring buffer mode is disabled and driver- or library-allocated ring buffers are released.

Syntax

int s16a_set_defaults(S16aDev *s16a_p);

Arguments

s16a_p

S16A device handle returned from s16a_open

Return

Return value from ioctl call to driver: 0 on success; –1 on error. If an error occurs, check the errno global variable for the error number.
