Hi, I've searched through the threads and haven't seen any posts about interfacing TI's THS1206 ADC to a TI5416 DSK. I'm a DSP newbie so I bought these parts to get running quickly for my thesis project. I've posted on comp.dsp, TI's discussion groups, etc. but I cannot seem to find anyone who has used this setup before. So, here is my urgent request for help: I have the THS1206M EVM connected through the 5-6K interface board to the 5416 DSK. I've generated code using TI's data converter plugins, but something is not working correctly and I cannot tell what it is. I only get 0's when calling dc_read defined in the TI DC API, so there could be a multitude of problems. My settings for code generation are: ADC address: 0x8000 Data shift: 4 DATA_AV polarity: High DATA_AV type: pulse Read/Write type: RD/WR Data Format: 2's complement Another question I have is: How do I route/handle DATA_AV as an interrupt on the 5416? The help files for the DC plug-in talk about referencing the BIOS .cdb file, but this is not an option in my plug-in window. I could also just try and figure what to do if someone could send me some source code with examples of accessing the 1206M from the 5416. I am using the ADC to sample 4 channels of ultrasound at high speed for DSP processing as part of a larger project. Any help with anything would be greatly appreciated as this project is for my thesis which is due in about 30 days... Thanks, Kevin
