In addition to interfacing to the various micro controller and digital signal processors from Texas
Instruments, this board also plugs into the TSW1100 card. The TSW1100 is a PC-based data capture
card. J7 connector is installed to allow the user to plug the ADS8472EVM directly and collect data for
analysis.
