Control PCF8574 IO using i2c-tools. Here is an example. Write data to IO. PCF8574 is a I2C chip which can expand IO up to 8 and the initial state of IO is HIGH. Different from other I2C chips, the PCF8574 has no register, instead, a byte to specify the address on that chip to write to is always used to control the IO: i2cset -y 1 0x20 0xEF
'Code for the keypad and LCD Microchip PIC microcontroller on the Microlab board v2 'microcontroller is responsible for: ' - Reading keypad ' - Displaying data on LCD ' - communication with main Microchip PIC microcontroller via I2C ' - providing 5 keypad lines to main Microchip PIC microcontroller (for compatibility) ' - receiving remote ...

To avoid the confliction of I2C address with other I2C devices, such ultrasonic sensor, IMU, accelerometers, and gyroscope, the I2C address of the module is configurable from 0x20-0x27. And its contrast can be adjusted manually. Another alternative option is I2C 20x4 Arduino LCD Display Module if more characters are required. Last update: V1.2:

pic16f15244-family-advanced-i2c-io-expander This code example implements an advanced 8-bit I2C I/O expander using the general purpose PIC16F15244 family of parts (PIC16F15245, PIC16F15244, and PIC16F15243).
Aug 19, 2016 · Alright then, let’s do this! I’ll try to make this as universal as possible, meaning that I’ll provide code examples in C for PIC and MSP430 microcontrollers. For PIC users I’m using the PICkit 3 with MPLAB X IDE v3.55; check out the Instructable Programming PIC Microcontrollers for initial setup of the project
