ARM Cortex-M Interfacing with Keyboards and LCD's (FREE! )

Free Courses : ARM Cortex-M Interfacing with Keyboards and LCD's (FREE! )

This coursetakes a step-by-step practical approach on how to writedrivers and librariesthat will allow your Cortex-Microcontroller to talk to Keyboards and Liquid Crystal Displays. It goes on to provide optimization methods such as accessing the LCD with 4-bits rather than 8-bits and also programming keyboards using thematrix arrangement approach.

We will start by differentiating between GPIO and SPIO, this will givestudents theunderstanding on how registers relates to IO ports then we shall write out the code to see how these registers actually work with inputs and outputs.

We shall look at how to write our own LCD Drivers and Libraries, we shall take a look at the pinout and how we interface with the microcontroller, take a look at how we control the shift registers inside the LCD,then we shall go on to code our own driver and library.The last section of the LCD chapter deals with writing data in4-bits to reduce the number of IO pins used for LCD.

The final chapter of the coursedeals with interfacing to keyboards, I will introduce how keyboards also conserve the number of IO pins by using the matrix arrangement and then we shall go on to write our keyboard driver and library. In a nutshell, this are the key areas we shall be looking at in this course :

• Keyboard driver and library coding
• LCD driver and library coding
• LCD 4-bits data transfer
• Keyboard matrix arrangement

If you interested in having bare-metal level access to keyboards and LCDs then this course is for you.
