大神们一起来讨论下:CC3200上打算接摄像头、SD卡、WIFI也必须用,这样会产生引脚冲突怎么解决?
C3200上接摄像头,再接SD卡的话,采用SDHost方式时CMD(pXCLK)引脚冲突了;如果采用SPI模块方式,MOSI引脚就冲突,要么占用了32.768的时钟引脚,要么占用摄像头的pDATA10。大神们来讨论下,谢谢!
你是用SD卡存摄像头的视频吗?

看这个参考,两者不冲突。
谢谢!是安排存储些图片或者视频的。
SD_SMD和Camera_pXCLK共用硬件引脚,软件使用时不影响就好。
可以参考http://www.ti.com/tool/TIDC-CC3200CAMBOOST 有详细的设计文件
你好,想问个问题,对于接sensor有点迷糊,CC3200是直接连OV3660的吗?还是中间要接ISP处理芯片的?还有这个功耗能做到多少?
