由于MFRC522的工作电压为3.3V,所以我们可以直接使用FireBeetle开发板的3.3 V引脚为其供电。 或者,如果您的开发板没有可用的3.3V电源引脚,也可以使用外部3.3V电源为其供电,但外部电源要与MFRC522共地连接。 当然,ESP32与MFRC522模块之间也要连接公共的GND,按照电路图所示连接相应的引脚。 由于我们将使用SPI协议与MF...

I even used the extended constructor for the SPI interface: Code: Select all SPI.begin(RFID_SCK, RFID_MISO, RFID_MOSI); I then started commenting out code related to the RFID reader. I found that I could create an instance of the MFRC522 class: Code: Select all MFRC522 rfid = MFRC...
