5.1 VEYE-LVDS-290/327接入FPGA平台
我们提供了一个接入demo（包括源代码）实现了VEYE模组通过LVDS输出视频到FPGA,然后显示到HDMI显示器功能，资料参考链接。
5.1.1 硬件信息
- 硬件平台：MIA701-PCIE开发板，FPGA芯片：XC7A100TFGG484
- 显示设备必须支持1080p/30或1080p/25的帧率
5.1.1.1 硬件接口建议方案
由于不同的FPGA开发板的Camera接口差异很大，如果开发板采用的2.54排针接口，我们建议采用如下方案进行原型开发时期的硬件连接方式。
- 采用我们官方的转接板，将我们摄像头模组的B2B硬链接模式转为FFC软排线连接。
- 使用淘宝购买0.5mm间距30pin的FFC排线插座转接板，信号转为2.54排针。此处link非官方推荐，仅供参考。
- 通过杜邦线等形式，转接信号到FPGA开发板。
5.1.2 软件信息
软件平台Vivado2018.1
