This application report presents guidelines for interfacing the Texas Instruments (TI) TLC5510 8-bit parallel-output analog-to-digital converter (ADC) to the TI TMS320C203 DSP data bus. The 8-bit ADC operates at a rate of 20 MHz. The C callable application program (assembly code) used to initialize the TMS320C203 and execute the code is also discussed. This report serves as reference information for further development of hardware and software. The contents include hardware schematics and associated program software, block and timing diagrams, and a program flow chart.
