interface tft lcd present on stm32f429i with 4x4 keypad

[Rg.11]

Hi stm community

I want to interface tft lcd present on stm32f429i with 4x4 keypad

is it able to interface please help me i just struck at this point

Presumably you mean the STM32F429I-DISC board?

The manual should indicate all of the free/available pins on the board.

Likely to be very limited as LCD+SDRAM eat most of the pins.

Yes on ​STM32F429I DISC board can we interface please kindly give me information as iam new to stm32

I'm not sure how interfacing a 4x4 key pad on an STM32 differs materially from doing it on any other MCU from the last 3 decades.

You presumably want to find 4 output pins and 4 input pins in the simplest implementation.

Or drive the outputs via a 2-to-4 decoder type IC

Seem to recall there being chips these days that would drive 8-led and offer and bunch or inputs/outputs.

Also perhaps an I2C Bus Expander type chip?

Going to START with you pulling the MANUAL for the board and identifying the free/available pins to do things with..
