I2C地址冲突:每个I2C设备都有一个唯一的地址,如果两个Arduinos使用相同的地址,通信将无法正常工作。确保每个Arduino上的I2C设备具有唯一的地址。可以通过修改I2C设备的地址或使用I2C地址转换器来解决冲突。 电源问题:确保每个Arduino和I2C设备都有足够的电源供应。如果电源不稳定或电流不足,可能会导致通信失败。使用稳定的...
Introduction of I2C There are two roles in the operation of I2C, one is “Master”, the other is “Slave”. Only one Master is allowed, and can be connected to many Slaves. Each Slave has its unique address, which is used in the communication between Master and the Slave. I2C uses ...
数据的传输速率在标准模式下可达100kbit/s,在快速模式下可达400kbit/s,高速模式下可达3.4Mbit/s。

If anyone has previous experience with this module or can provide some guidance on how to approach I2C communication with it, it would be greatly appreciated. Additionally, I wonder if it's possible to use a library designed for the PN532 module instead of one specifically for the PN7160 ...
I2C总线的Arduino库函数 I2C即Inter-Integrated Circuit串行总线的缩写,是PHILIPS公司推出的芯片间串行传输总线。它以1根串行数据线(SDA)和1根串行时钟线(SCL)实现了双工的同步数据传输。具有接口线少,控制方式简化,器件封装形式小,通信速率较高等优点。在主
