This application report provides guidelines that take you through everything from configuring the ADC and related registers correctly, responding to interrupts, and board design recommendations; this may be particularly useful for first-time users of the TMS320C2000™ digital signal processor (DSP) platform devices and for firmware engineers with less exposure to the analog world. Various system consideration issues are discussed, such as setting sampling rate, proper sequencing of input channels for efficient transfer of digital counts to the system’s data memory, inputting the driver/filter circuit, and power supply and calibration. Information from various documents was compiled to form a handy guide for those designing with the onboard analog-to-digital converter (ADC) that is available on the TMS320F28xx/28xxx generation of digital signal controllers (DSCs). The associated code demonstrates this implementation using an F280x eZdsp™ board. It can be used as a software framework for a new design which uses this ADC extensively.
