Hi guys,
Im trying to make a fast and real time RS-232 of computer to SPI converter, to control a 12 bit input DAC.

Hi,
a USB to SPI converter would be even better.

I have routines for both(USART + SPI) for Atmel AVR. You can combine them to get USART to SPI.

I can also do USB to SPI, send I private msg if interested. Which DAC u are using?

Hi Avinash,
I am using AD8804 from analog devices. Could you send me the code for USART to SPI conversion?
