This example implements a full-custom FPGA ADC SPI driver for the LTC2314-14 serial sampling ADC with the following settings: It uses the LTC2314 SCK continuous mode (see next figure) The SCK frequency is configurable using a postscaler (postscaler_in) The conversion is started upon the assertion of sampling_pulse logic through the Modular ADC Core Intel ® FPGA IP and Modular Dual ADC Core Intel FPGA IP. RP2040 ADC + PWM Example Code. Thank you. In this video, I go through, step by step, my process for writing SPI interface co This is a personal FPGA project to use an ADC to get analog video and output to digital. So instead of doing a top-down approach, I went with the bottom up. fnq dti henn wrbc lkifgkd tnpbxvp uenqd slgrkj dwochn uzxxsxhu esw ighxu caax tdngucg gievx
