Hello I want to ask a question. I currently need to use I2C chip which is the PCF8574.
I need to interface it with LED, LCD and a 4x4 Keypad. The thing is, my microcontroller has no port specified for SDA and SCL. The name of my microcontroller is VSX-6116. Attached is the datasheet and list of available ports. So can I connect the 2 wire line which is SDA and SCL to the GPIO ports? Including the pull-up resistor required by the 2 lines.
