Sets the voltage of an analog output channel by serially clocking in 16 bits to a D/A converter using the
following format:
channel is the D/A converter output channel to write. channel should be passed as
where slotnumber is 0–6, and channelnumber is 0–7
or
where slotnumber is 0–6, and channelnumber is 0–7.
rawcount is a value corresponding to the voltage on the analog output channel (0–4095). The follow-
ing rawcount data correspond to the analog outputs indicated.
0 if successful.
–1 if rawcount is greater than 4095.
unsigned int rawcount);
• Program bits (D15…D12)
• New data (D11…D0)
SPD—Speed control bit: 1 = fast mode (default), 0 = slow mode
PWR—Power control bit: 1 = power down, 0 = normal operation (default)
