The Octal 12 Analog-to-Digital Converter Card uses the Microchip MCP3304 to provide eight channels of analog input. The card uses one slot on the FPGA card and must be paired with the "adc812" FPGA peripheral. Linux support includes both TCP and a command line interface to the card. Input from the card is event driven so your code does not need to poll for ADC readings. Click here for more information.
