Adafruit CAP1188 Library: Arduino library for the Adafruit CAP1188 8-Channel Capacitive Touch Sensor Breakout; Adafruit CCS811 Library: This is a library for the Adafruit CCS811 I2C gas sensor breakout. SoftI2cMaster is a software i2c library that can use any two Arduino pins for SCL and SDA. It has an i2c clock rate of about 65 kHz. TwiMaster uses the ATmega TWI hardware so you must use the hardware SCL and SDA pins. It is setup with a i2c clock rate of 400 kHz. 26 Dec 2011 new version as file i2cv2.zip The very first thing we need to do is to include the Wire.h library to get the i2c interface on the Arduino working. Then we include the Adafruit BMP085 library and create a sensor object. (bmp in this case) #include <Wire.h> #include <Adafruit_BMP085.h> Adafruit_BMP085 bmp; The bmp.begin() function returns a boolean value depending if the i2c ...

It is setup with a i2c clock rate of 400 kHz. 26 Dec 2011 new version as file i2cv2.zip In I2C mode it can have two different addresses, achieved by connecting the SDO pin either to Ground (for base address = 0x76) or to Vdd (for base address +1 = 0x77). In SPI mode it has the usual arrangement of 1 clock, 2 data (one for each direction) and a device select pin (CS). The library I wrote and describe here only supports I2C. Apr 27, 2020 · The Wire Library. To use the Arduino’s built-in I2C interface, we will use the Wire library. This library is included with the Arduino IDE, so there’s no need to install it. The Wire library has ready-made I2C functions to make the programming easier for us. To use the functions in the Wire library, we first need to add it to our sketch.
