Based on the information provided, there doesn't seem to be a specific Arduino library for the PN7160 module. However, you can still communicate with the module via I2C by writing your own functions, as demonstrated in the code snippet you provided. As for using a library designed for the...

i2c总线最多可以挂127个外设,由IIC地址决定,一个字节即8位地址,减去1位广播地址,是7位地址,2^7=128,但是地址0x00不用,那就是127个地址, 所以理论上可以挂127个外部设备。 发现iic设备demo #include <Wire.h> void setup(){ Serial.begin(115200); ...
