pinMode(VSPI_SS, OUTPUT); pinMode(HSPI_SS, OUTPUT);Then, use the usual commands to interact with the SPI devices, whether you’re using a sensor library or the SPI library methods.You can find an example of how to use multiple SPI buses on the arduino-esp32 SPI library. See the ...
However if we simply intialise two instance of the SPI class for both of these buses both can be used. However when just using these the Arduino way only will actually be outputting at a time. Logic analyser capture is in the same folder as this example as "multiple_bus_output.png" cr...

In arduino-esp32,ESP32-S2 SPI buses are labeled as follows: #elif CONFIG_IDF_TARGET_ESP32S2 #define FSPI 1 //SPI 1 bus. ESP32S2: for external memory only (can use the same data lines but different SS) #define HSPI 2 //SPI 2 bus. ESP32S2: external memory or device - it can...
I2C address conflicts are a common problem, and in this article, I'll show you how to resolve them by creating multiple I2C buses with your Arduino.,/p> I'll demonstrate how the TCA9548A I2C Multiplexer works by using two identical OLED displays and sending them unique data even though ...

(Inter Integrated Circuits).Comparing I2C with SPI, I2C has only two wires while SPI uses four and I2C can have Multiple Master and Slave, while SPI can have only one master and multiple slaves. So there are more than one microcontroller in a project that need to be masters then I2C is...

If you want to send commands to the board on the fly, you will need a second development board on a second USB port communicating with the first using some sort of bus (UART, I2C, SPI, etc.). For what it’s worth, if you’re trying to record and play back inputs on the same ...
