Example code for talking to aTMP102I2C thermometer, like those available from Sparkfun, for example. Rather heavily based on some code I found in the forums, some samples, and a bit of personal investigation to make it all work. Based on my testing, the sensor overreads by around 5 degr...
There are both 7- and 8-bit versions of I2C addresses. 7 bits identify the device, and the eighth bit determines if it's being written to or read from. The Wire library uses 7 bit addresses throughout. If you have a datasheet or sample code that uses 8 bit address, you'll want t...
Note the above code snippet. Press S1 LED1 turns on and stays on. Press S2 and LED1 turns off and stays off. (This could also be a motor control for example.) In each case pressing S1 or S2 returns a 1 or 0; the "if" command does the rest. Another note is the () must be...
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...

When the I2C slave receives a string sent from I2C master, it prints the received string. Setting up Arduino Uno to be I2C Slave First, select Arduino in the Arduino IDE in “Tools” -> “Board” -> “Arduino Uno” Open the “Slave Receiver” example in “Examples” -> “Wire” ->...
把esp32和mpu60插入面包板,用跳线连接二者,使用i2c通信协议,一共需要四根线,分别是电源正vcc,地gnd,数据sdl和时钟scl。 打开arduino ide,在库中搜索mpu6050,然后安装它。第一个库,我的已经安装好了,如下图。 打开file-example-mpu6050-mpu6050_raw,有现成的实例代码。
