Based on the MCP4728 chip from Microchip.
Set a voltage:
sudo i2cset -y 1 0x60 0x40 0xff 0xf0 i ^^ ^ < Voltage bits
explanation of the arguments:
-y don't ask confirmation 1 number of the I2C bus (0 on older raspberry pi's) 0x60 address of the DAC, use 0x61 for the other DAC. 0x40 configuration: normal. 0xff high 8 bits of the value 0xf0 lower four bits of the value (in the high nibble)
