I'm having a real heck of a time with this chip, the TI ADS1256 A to D converter. Has anyone else here programmed this device before with a uC . I am using an atmel atmega 162 . All of my outputs look alive and well, and the ADC sends back semi random data when I attempt to just read a configuration register. If anyone here has example code (pseudo code, assembler, c, any processor) I would be relieved to just see some example of the proper sequence or timing. I've been through the data sheet several times and have cut back from a complete configuration and data acquisition to a very simple "what's in this register" and still don't have it working. TI doesn't have any examples of coding on their website as far as I can tell. I'm truly at a loss here, as the signals all look fairly clean (SPI signals), as far as I can tell I'm sending the right sequences and still I just get random gibberish from the chip. Thanks!
