AN2063: Blood Pressure Recorder

I did this project to compare a design using the Cypress PSoC device to a project I did a number of years ago. The circuit uses a pressure sensor to read and display the pressure in a blood pressure cuff and record systolic and diastolic pressures. The original design used a microprocessor, EPROM memory, A to D converter, opamps for filters and amplifiers, and clue logic to tie it all together. The PsoC design uses one 8 pin dip to replace all of those items.
