How to complete the design?

Completing the hardware side of the ADC design is relatively easy. Most of the circuits have already been either constructed or discussed. From Lab 8, you constructed the RC-DAC. This will need to be connected to the ADC test circuitry you constructed in lab 5. After this is done, you will need to build the multiplexed LED display. Finally, you will need to modify the successive approximation ADC program you wrote in Lab 6 so that the program drives the RC-DAC (rather than the R2R ladder DAC), the binary search converges to a 6-bit digital number (instead of 3-bit), and the quantized number is used to drive the dual-digit (rather than single digit) display.
