This KBA provides a minimal code example with Arduino Uno board for the TLI493D-W2BW 3D magnetic sensor with the in silicon A0 address. The I2C address would be 0x6A for write or 0x6B for read. In the 7-bit format, the I2C address translates to 0x35. Code ...
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...
ESP32 I2C Scanner – Arduino Code Example The code example down below does the following: We start with defining initializing the I2C peripheral. And we’ll also initialize a serial UART communication to print back the results to the PC serial terminal (Arduino Monitor). Then, we’ll start ...
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...
