The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Controller board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices.

2017年2月3日 · To make it easier to make shields which use I2C the manufacturer added the SDA/SCL pins in a known location. For both boards they are connected to the correct pins for that board. A similar remark applies to the later versions of the Mega2560 board. You can use either pins: the ones marked SDA/SCL or the appropriate pins for the board to hand.

2020年10月31日 · I2C Pins 23, 24 as A4 and A5. Since SPI communication also has its disadvantages such as 4 essential pins and limited within a device. For long distance communication we use the I2C protocol. I2C supports multi master and multi slave with only two wires. One for clock (SCL) and another for data (SDA).

I2C - Inter Integrated Circuit GPIO 2 and GPIO 3 - the Raspberry Pi's I2C1 pins - allow for two-wire communication with a variety of external sensors and devices. The I2C pins include a fixed 1.8 kΩ pull-up resistor to 3.3v.

2022年11月2日 · On the front of the board are three address pins, labeled A0, A1, and A2. Just like the jumpers, these pins allow you to change the I2C address to connect multiple boards by connecting them to VIN in various combinations. The default I2C address is 0x20. The other address options can be calculated by “adding” the A0/A1/A2 to the base of 0x20.

2024年11月18日 · In this article, we explored the Arduino Pro Micro pinout in detail, covering the digital I/O pins, analog input pins, PWM pins, and communication interfaces. We provided examples and explanations on how to use these pins and features in your Arduino sketches.

2023年5月24日 · If you happen to need more than 16, it's possible to set the I2C address with a special address-change command that is saved to the onboard non-volatile EEPROM memory. The default I2C address is 0x49. The other address options can be calculated by "adding" the A0/A1/A2/A3 to the base of 0x49.
