目前在调试3518ev200的音频部分,发现再跑例程sample_audio例程时,只有AIAO环回时才能够左声道入左声道出,右声道入右声道出 在跑file->AO时,发现2通道的pcm文件智能播放一个通道,请问有人知道这个是为什么? 我已经修改了配置信息 并且修改TrackMode 为normal模式 都不管用,求论坛大神予以解答! 谢谢2017-12-204 0 2905

目前正在调试,利用SDK的工具ssp_write命令发出的信号都是先cs拉低之后才有数据传输,但是目标芯片是CS为高才开始进行数据读取,所以需要在发送数据时将cs设置为高,通过程序发现可以在设置SPI_IOC_WR_MODE时,增加SPI_CS_HIGH,配置后读取mode也是正确的配置的,但是波形还是CS至低才开始发送数据,并没有什么改变,请求大神解答2017-11-234 0 3308
