Hi,
I would be very grateful if someone with much more skill than me could take a look at the datasheet for the TLV5618 serial DAC here and tell me exactly what they would clock out of a microcontroller to set the output of 'A' to 0, 2.5, and 5V?
I've been trying to do this for a week or two, and I can't seem to get the DAC to respond to my commands correctly. The output changes, but often not as I would expect, and sometime gets 'stuck' on certain values for a number of update cycles.
You might need to show me the bit order, as I think that my shiftOut routines aren't presenting the data correctly.
Assuming 2.048v on Vref
