#ADC - Read Analog/Digital Converter Input
<adc>, <mode> and <dir>.
3.5.5.1.17. Digital/Analog Converter Control - #DAC
#DAC - Digital/Analog Converter Control
AT#DAC=
<enable>
[,<value>]
Set command enables/disables the DAC_OUT pin.
Parameters:
<enable> - enables/disables DAC output.
0 - disables pin; it is in high impedance status (factory default)
1 - enables pin; the corresponding output is driven
<value> - scale factor of the integrated output voltage; it must be present if
<enable>=1
0..1023 - 10 bit precision
Note: integrated output voltage = MAX_VOLTAGE * value / 1023
AT#DAC?
Read command reports whether the DAC_OUT pin is currently enabled or not,
along with the integrated output voltage scale factor, in the format:
#DAC: <enable>,<value>
AT#DAC=?
Test command reports the range for the parameters <enable> and <value>.
Example
Enable the DAC out and set its integrated output to the
50% of the max value:
AT#DAC=1,511
OK
Disable the DAC out:
AT#DAC=0
OK
Note With this command the DAC frequency is selected internally.
D/A converter must not be used during POWERSAVING.
DAC_OUT line must be integrated (for example with a low band pass filter) in
order to obtain an analog voltage.
For a more in depth description of the integration filter refer to the hardware user
guide.
3.5.5.1.18. Auxiliary Voltage Output Control - #VAUX
#VAUX- Auxiliary Voltage Output Control
AT#VAUX=
[<n>,<stat>]
Set command enables/disables the Auxiliary Voltage pins output.
Parameters:
<n> - VAUX pin index
1 - there is currently just one VAUX pin
<stat>
