We provide an Arduino Library for SoftwareI2C, click on here to download it. Example#1: Scan I2C device addressConnection Here we will show you how this works via a simple demo. First of all, you need to prepare the below stuffs: ...
As of Arduino 1.0, the library inherits from the Stream functions, making it consistent with other read/write libraries. Because of this, send() and receive() have been replaced with read() and write(). Note There are both 7- and 8-bit versions of I2C addresses. 7 bits identify the d...
Arduino EEPROM Example Number1:In example 1 we will write a simple program which displays the data stored in the EEPROM, delete/erase the stored string message, and asks again for the new message to enter. You can enter the text using the Arduino’s serial monitor. For the best ...
I2C (Inter-Integrated Circuit) 集成电路总线是I2CBus的简称, 是一种串行通信总线, 使用多主从架构. 飞利浦公司在1980年代为了让主板, 嵌入式系统或手机用以连接低速周边设备而发展. I2C的正确读法为"I-squared-C"。 I2C只使用两条双向漏极开路(Open Drain): 串行数据SDA及串行时钟频率SCL总线, 且利用上拉电阻...
Example IntroductionThere 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 two ...

SCL --- I2C 时钟线(接A5) (可以看到模块后面有一个U2芯片,就是用来稳压的) 下载安装最新库 https://learn.adafruit.com/monoc ... ibrary-and-examples 其中OLED模块的专用库名称是SSD1306,另外需要配合图形库GFX操作 不建议使用NB的U8glib,因为这个库强大到哭,所以编译和下载都太消耗时间了。 将这些...
Here is a simple example of how you might write to the PN7160 using I2C: void write_to_pn7160(unsigned char *buffer_write, unsigned char num_bytes){ unsigned char buffer_write_nfc [9] = {0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}; // Your code here to write...
