By using simple i2c and SPI input/output expanders we have reduced the number of pins (only 2 pins are needed for i2c) while still making it easy to interface with the LCD. I am trying to add this to an existing system that already uses the smbus library. This type of LCD is ideal for displaying text and numbers, hence the name 'Character LCD'. Connect adapter's GND, VCC pins with NodeMCU GND, Vin accordingly - here I need to explain one thing. The author didn't commit anything since 2014, so the development of the library can be considered dead from that side. The Hardware I/O library allows access to the computer's hardware periperals, such as digital inputs and outputs, serial busses, and the like, in a fashion similar to the Arduino plaform. I've seen LiquidCrystal_I2C has a new version released 6month ago (on Github). The PCF8575 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I2C interface [serial clock (SCL), serial data (SDA)]. We have libraries available for many I2C devices in the library bundle. I2C uses only two bidirectional open-drain lines ( open-drain means the device can pull a level down to ground, but cannot pull the line up to Vdd. Open in Desktop Download ZIP. begin(int sda, int scl) , i. GPIO expanders. This utility program has a number of while() loops used to send and receive bytes across the I2C bus, and every one of.
