你好:
问题1:
我们在产品设计的时候,用到了ESP8266的I2S模块。和音频编解码芯片的连接如下:
I2SO_DATA --> CODEC I2SI_DATA
I2SO_BCK--> CODEC BCK
I2SO_WCK --> CODEC WCK
I2SI_DATA --> CODEC I2SO_DATA
I2SI_BCK--> CODEC BCK
I2SI_WCK --> CODEC WCK
请问,如果按照以上连接的话,ESP8266 的I2SI 和 I2SO的BCK和WCK是短接的,会涉及到GPIO0 和GPIO15。这样会不会影响ESP8266的启动呢?
问题2:
如果我们使用HSPI的overlap的话,到了spics1 引脚, 那我们应该怎样处理打印接口TXD0呢?因为这两个引脚是共用的?
期待回复,谢谢!!!!
