Overview of ADC and FIFO Data Processing 01 ADC (Analog-to-Digital Converter) captures analog signals and converts them to digital values. 02 FIFO (First-In-First-Out) buffer temporarily stores data before further processing. 03 SPI (Serial Peripheral Interface) is used for communication between the ADC and FIFO. 04 Data Ready signal indicates when new ADC data is available for transmission. 05 Chip Select (CS) controls the start and end of data transmission.
SPI Communication Flow Data Ready Pulse The Data Ready signal indicates that the ADC has finished converting an analog signal into a digital value. Chip Select (CS) Activation CS goes low to initiate data transmission between the ADC and FIFO via the SPI protocol. Data Transfer and Storage Once CS returns high, the converted digital data is successfully stored in the FIFO buffer for further use.
