This function send a command to change the output voltage of the LTC1663 DAC. The I²C address used should be one in the range [0x20..0x27] (depending on device) and NOT the SYNC address (0x7E).
- Parameters:
-
device A String containing the K-Net name of the LTC1663 device. command Command Word (see LTC1663 documentation)
- bit 0 SY
- 1 Allows update on Acknowledge of SYNC Address only
- 0 Update on Stop condition only (Power-On Default)
- bit 1 SD
- 1 Puts the device in power-down mode
- 0 Puts the device in standard operating mode (Power-On Default)
- bit 2 BG
- 1 Selects the internal badgap reference
- 0 Selects the supply as the reference (Power-On Default)
- bits 3-7 Not used
- Parameters:
-
value 10-bit unsigned value [0..1023]
- Returns:
- an error code:
- <0 error code
- 0 cannot open the K-Net device
- 1 DAC voltage has been changed successfully
