通过SPI,ESP32可以与其他同样使用SPI连接的传感器相互传输数据。 SPI的传输采用同步的时间线,也称为共享时钟信号,这有助于确保传输的数据准确一致。 SPI主要应用于需要短距离、高速串行通信的场景,例如需要快速同步数据的显示屏、SD卡读取器、加速度传感器等。 可以将SPI想象成一种精密的对话方式,其中主设备(ESP32)和...
If using these pins is imposibble. Why does the datasheet mention that using SPI pins as GPIO is not recommended instead of explicitly stating that you can't? Thanks again. Because technically, it's possible to add another SPI device in parallel with the flash, and you'd use those ...

SPI receiver (slave) example. This example is supposed to work together with the SPI sender. It uses the standard SPI pins (MISO, MOSI, SCLK, CS) to transmit data over in a full-duplex fashion, that is, while the master puts data on the MOSI pin, the slave puts its own ...

It seems like there are two SPI buses, and I've heard that I shouldn't use the HSPI bus because it's connected to the onboard flash. So, I decided to use the VSPI bus. However, there aren't standard pins. I was initially confused by the odd naming scheme (i.e. SPID and SPI...
