There were a lot of modifications and trials in designing each part. Also, I really wanted to create a board that would give me the sensation of a run on the slopes. Why? Because I am a person who believes in what I see, not in theory alone. I spent 2 years testing and designing Legendary. Since I am French living in the US, I chose the colors blue and red to represent both countries. The board needed a name, and over a glass of wine with my wife, she suggested XBoard because of my first name. This came about in early 2016 when I made my first DIY, a mountain board with 12S7P 6374 motor. Complete Atmel Studio 6 Project (For ATmega8 running 16MHz) (Load the file KeyboardTest.I wanted to share some details about the creation of XBoard.
#XBOARD PS2 PC#
Schematic for ATmega8 and PC Keyboard Interface. Connect the keyboard and LCD as per the schematic.Set LOW Fuse as 0xFF and HIGH Fuse as 0xC9.A hex file will be generated inside Debug folder inside the project folder.Using solution explorer open the file KeyboardTest.c (the main file of project) and copy/paste the above code.Under AVR GNU Linker / Libraries -> Library search path add the lib/kb folder to the search path list.Hit Alt + F7 to bring the project option dialog.No need to add them to project as you did for lcd lib since it is precompiled.

Please see the related tutorial for more detail on LCD interfacing. The example uses our popular LCD library for AVRs to control the LCD Module.
#XBOARD PS2 HOW TO#
The following example shows you how to display string entered using keyboard to LCD display module. 0 if the buffer is empty and wait parameter is 0. Non-zero : if you do not want to wait if the buffer is empty. If their are some characters pending the the buffer it they will be returned one by one (for each call) in a FIFO(first in first our basis) basis.Ġ: If you want to wait till any key is pressed. If wait is 0 then the function returns immediately if the queue is empty returning a 0. When wait is non zero the the function will wait if the queue is empty until any character is available in the queue.
#XBOARD PS2 PS2#
Internally it initialize the ps2 system and sets up the INT0 isr for handling PS data traffic.įunction to read a character from the keyboard buffer. After that the CPU can read the characters anytime when it is free.įunction to initialize the PS2 keyboard library. That means even if the CPU is busy doing something else and a character arrives from the keyboard, it will be automatically buffered in a queue. The keyboard library automatically translates the scan codes to ASCII characters and buffers them in a FIFO queue. The PS2 Keyboard library for AVR has only two functions one for initializing the library and one for reading a ASCII character from the queue. If we can interface the PC keyboard with an AVR MCU we can create a whole lot of interesting applications! This tutorial will focus on our easy to use PS2 keyboard library for AVR MCU. When a text entry is required it is the best method. A PC keyboard is an old and trusted human machine interface.
