Before we get started into programming I2C using two Arduinos. We need to learn about the Wire library used in Arduino IDE.. The library <Wire.h> is included in the program to use the following ...

gpio/interrupt: program that based on gpio/led_blink. Now we can toggle led state depending on logic level on INT0 using interrupts. uart/uart_drv: simple uart driver. we can test in with led, if we ...

I2C as many of you know, is a simple serial interface for many peripheral devices to micro controllers, but it can quickly become confusing to people who may not be accustom to it. Because of that,… ...

Arduino is the now-famous microcontroller that has set a portion of the maker ... How To Program Arduino The Easy Way With Arno Kit. By ... An I2C digital temperature sensor to introduce between ...

The Arduino is a more flexible I2C device because it can be either a master or slave device on the I2C bus. Because of the Linux driver, the Overo can only be an I2C master. There is an Arduino sketch ...

Next steps shows how the master (Arduino) reads from the slave I2C device. Wire.requestFrom(address, 1) command expects to receive 1 byte of data from the TC74 sensor. Wire.available() waits for data ...

I wrote some I2C sniffer code for a silabs C8051F340 MCU one time. On that MCU, it has specialized I2C hardware, so you only have to peek/poke certain registers to make the I2C bus do what you want.

The DF2301QG offline voice recognition module is shown connected to an Arduino clone over I2C board, but it could support any other hardware with UART or I2C including other Arduino boards, Raspberry ...

Arduino Code with Basic Text and Graphics Functions. Once the connections are ready you can start programming the Arduino. Whether we use I2C or SPI interface for the OLED display, the code is almost ...
