ESP32模组芯片

请问乐鑫的芯片ESP32-D0WDQ6里面的管脚:SENSOR_VP、SENSOR_CAPP、SENSOR_CAPN、SENSOR_VN,这四个管脚能否配置成普通输入IO来使用呢?因为我看到datasheet上面的SENSOR_VP与SENSOR_CAPP,SENSOR_CAPN与SENSOR_VN上面都互相串上一个270pF电容,请问能否把电容去掉直接引出IO当作输入使用?

ESP32模块的SPI问题

请教个问题,在使用ESP32的SPI硬件驱动外设的时候,遇到些问题,想问下SPI的CLK脚能否置高的呢?官方给出的例程中CLK脚在SPI没有发送或者接收数据的时候是保持低电平的,官方给出的API函数也没有可以配置成高的接口

How to use Serial Port?

I'm using serial port of Uart0 to communicate with an external device, but it's already default as a system print window. I want to ask if it can be configured as an ordinary serial port to communicate with other devices? Thanks!
