Driving AD922x with DCMI

Driving Extern High-speed ADC with STM32F4 DCMI

项目介绍

对于一般的 MCU 来说,通常难以驱动外部的中高速(10MSPS~50MSPS)ADC,对于这类并行输出的 ADC,可以采用 FPGA 驱动等方案。但如果可以使用 MCU 直接驱动 ADC,并可以同时完成项目中其他需求,就可以达到降低系统成本、复杂度,缩短开发周期的目标。

本项目使用具有 DCMI 接口的 STM32F407(关于还有哪些 STM32 系列芯片具有该接口,请点击此处查看),驱动外部高速 ADC(up to 54MHz)。实验测试使用的是 ADI 的 AD922x 系列并行 ADC (AD9220 -10MSPS, AD9224-40MSPS,该系列其他型号请参考 ADI 官网)

硬件

见 AD922x-DCMI.pdf

软件

使用 ST 库函数 V1.8.0 版本编程,如需参考,可自行建立基于库函数的项目工程
