I2C code to write the DAC MCP4725

[tumbleweed]

addr var byte
addr = $C0 ;$60 <<1

writedac4725:
I2CWRITE sda,scl,addr,[4000] '12 bit value
PAUSE 10 ' Wait 10ms for write to complete

That'll do a fast-mode write to the DAC register as long as the "12-bit value" is <4095, so you could remove the 'PAUSE 10'.
If the upper control bits are '01x' then it'll possibly write to the DAC + EEPROM, depending on the actual value.

Isn't necessary the control byte?

In fast mode (with the upper two bits 00) you only need two bytes.
If you want to use the EEPROM function you need all three bytes.

Of course, both modes need the address byte too.
