Hi,
I am doing a project that involves sending data to DAC.The DAC I am using is TI made DAC8581 that has a serial data input method. I am using TI's LM4f232 evaluation board,which has to send data to DAC. I am facing a few problems and would greatly appreciate any help on them:
1. The board Lm4F232 does not have a dedicated pin for getting the System Clock. The DAC needs the clock for its functioning. Moreover I willbe transmitting 16bit data in a serial fashion (as DAC has serial input). How do I do this. I intend to send the bits 1 at a time onto a GPIO pin thats connected to DACs serial input.
2. I believe the delay should be 45us between data bits at input. Is this correct (22.22kHz)?
Please help with interfacing and programming the DAC.
