HOW TO REPLACE ARDUINO WIRE LIBRARY SERIAL
The I 2C is a multi-master, multi-slave, synchronous, bidirectional, half-duplex serial communication bus. I 2C (i-square-c) is an acronym for “Inter-Integrated-Circuit” which was originally created by Philips Semiconductors (now NXP) back in 1982.

7.1 ESP32 I2C Scanner – Arduino Code Example. 4 ESP32 Change Default I2C Pins (SDA, SCL). 2.0.1 I2C Modes & Communication Speeds. MX7219_WRITE(0x0c, 0x01) //On power-down mode is 0，normal mode is 1 MX7219_WRITE_byte(dat) //The data figure on LED MX7219_WRITE_byte(address) // The address code of the LED Void MX7219_WRITE(unsigned char address,unsigned char dat) Void MX7219_WRITE_byte(unsigned char DATA)ĭigitalWrite(MAXPINDIN,DATA&0x80) // Extracting a bit data Unsigned char y //occupies bytes on the memory Unsigned char x //occupies bytes on the memory Int MAXPINDIN = 8 // Define Digital Port 8 Int MAXPINCS = 9 // Define Digital Port 9 Int MAXPINCLK = 10 // Define Digital Port 10 Operating Temperature > 0 Degree Celsius ~ 50 Degree Celsius | Typical Temperature: 25 Degree Celsius. Operating Current > 320mA | Max Operating Current: 2A. 
Operating Voltage > DC 4.7 v ~ 5.3v | Typical Voltage: 5v. If you want to learn more about the MAX7XXX series, just download the components datasheets below. The library which is use on this lab can cope both types of devices, and the visual appearance are both same. The MAX7221 or MAX7219 is more suitable for controlling LEDS, if you’ll going to switch from Arduino to a different controller you need to use the MAX7221, this chip support fully SPI compatible interface. The library witch has been used on this demo can support up to 8 cascaded device, which add up to 512 LEDS that be light individually using 3 pins on your Arduino. If you going to control more that 8 7SEGMENT display or more than 64 LEDS the chip can be cascaded. These chip it has a single resistor and 1 or 2 capacitors, the data is send to the chip using a SPI compatible protocol using 3 of the digital pins on the Arduino. The MAX7221 and MAX7219 provide as easy way to control an array of 64 LEDs or up to 8 digit made of 7 SEGMENT display with a minimum of electronic components. below are the device details and electronic parts required. The serial driven matrix are dynamic it can display the LED MATRIX row by row or column by column. The LED matrix can be driven in two ways parallel or serial, in this test were going to use serial communication in order to save the interface. The 8×8 Matrix LED you can adjust brightness by using Arduino Sketch, the 8×8 LED has many applications in real life such as electronic display panel or signage display projects and display clock, etc.
