The 2 available SPI buses are called VSPI and HSPI. This leaves HSPI and VSPI for interfacing SPI Devices. I am rather stuck on how to change the bus and how to set the pins for it. esp32集成了4组spi外设。 spi0和spi1在内部用于访问esp32所连接的闪存。两个控制器共享相同的spi总线信号,并且有一个仲裁器来确定哪个可以访问该总线。 spi2和spi3是通用spi控制器,有时分别称为hspi和vspi。它们向用户开放。. The spi_master driver uses the following terms: Host: The SPI peripheral inside the ESP32 initiating the SPI transmissions. включить контакт импульсных резисторов pinMode(30, OUTPUT); //VSPI SLCK pinMode(XX, OUTPUT); //HSPI SCLK. Most peripheral signals in ESP32 can connect directly to a specific GPIO, which is called its. Note There is a significant difference between the 2 boards, which is not necessarily obvious: their widths. HSPI and VSPI are free to use, and with the spi_slave. When using the ESP32 with the Arduino IDE, the default I2C pins are: GPIO 21 (SDA) GPIO 22 (SCL) If you want to use other pins when using the wire library, you just need to call: Wire. How does it know which SPI peripheral to choose since ESP32 has multiple SPI peripherals? SPI1: VSPI MOSI (GPIO23) VSPI MISO (GPIO19) VSPI SCLK (GPIO18) SPI2: HSPI MOSI (GPIO13) HSPI MISO (GPIO 12) HSPI SCLK (GPIO 14) For example, in my custom board I have selected to use SPI2 and use VSPI pins for something else.
