BOOT模式用于运行ESP32上的程序,而FLASH模式用于上传程序到ESP32。Strapping pins(引脚配置开关)用于配置ESP32的工作模式。通常情况下,带有内置USB/Serial的开发板会自动将这些引脚配置到正确的状态,以支持烧录或启动。然而,如果其他设备使用这些引脚,可能会导致ESP32进入错误的模式。 具体而言,Strapping pins是一组用于配...
Here, the SPI Master is communicating with two SPI slaves. The individual pins of the SPI master are connected to SS of each slave. SPI Pins Let's discuss the SPI Master and Slave pins on the Arduino board. The ICSP Header includes 6 pins. The structure is shown below: The pin number...

erase, and rewrite individual bits of data from the sensor’s memory. This example uses SPI EEPROM 25AA080C device from Microchip Technology with the Arduino®Mega 2560. Before using this example, wire an EEPROM to the SPI pins on your Arduino as described: ...
// OPTION 1 (recommended) is to use the HARDWARE SPI pins, which are unique // to each board and not reassignable. For Arduino Uno: MOSI = pin 11 and // SCLK = pin 13. This is the fastest mode of operation and is required if ...
Only small complaint is if you use a bread board you have to bend the pins a little to get it to stick in because the PCB contacts the bread board before the pins are fully in... small complaint but for the price well worth it. This also works with 5 or 3.3 V power so good ...
