We are using the EVAL-SDP-CB1Z-ND board with the ADSP-BF527 on it. Our design requires that several seconds of data from an ADC board be collected at a time. We have the eval software provided and were able to successfully loop the process of data collection to allow for longer periods of data but the API housed on the blackfin itself is limiting us. It appears that the data does not stream through the USB port but instead enters a queue which then transfers the data after the sample size has been reached. The queue size is fixed in such a manner that we cannot gather the amount of data we need without the queue filling and stopping the collection. This results in a loss of data with loop execution. We have a few ideas how we could modify the existing file to support our immediate needs but we do not have the source file that is installed on the blackfin. Our final product will have an interface that we write ourselves so this is really only intended as a "band aid" fix to get us into testing until our software resources free up. Unfortunately, this problem in the GUI was unforeseen and we are at a standstill. Can you please provide the source file for the Blackfin 527?
