Chapter 11 The Butterfly LCD

isn’t

hown on the LCD because there isn’t one in the LCD character set. However,

have this character sense all you have to do us use

they say, will be left to the

tudent. (Teachers make this statement not because they want to educate the

at’s just

e.)

that much of C programming for microcontrollers uses various

ricks’ to modify C to be more efficient for a specific microcontroller and a

ese tricks are often found by reading programs written by

xperienced programmers. You have access to the Butterfly software as modified

2 .zip, and I suggest you read it since

ese guys are the real experts. But do be careful. One of the main reasons to use

so be sure you make you tricks easily retrickable for

ther systems.

u’re familiar with C and the Butterfly software, go to the WinAVR
irectory and find the avr_libc user manual. At 185 pages, it provides excellent
f the Standard C Library for the ATMEL’s
VR. It also provides some other goodies, such as start up examples and good
solid example code to learn from. Since, they did such a good job documenting
this resource, I’ll go no further, other than to say that this library will likely
become an indispensable tool for your programming future.

Well, I hope you met your goals for using this book.

You should have gained a basic understanding microcontroller architecture. You
should have an intermediate understanding of the C programming language. You
should be able to use the WinAVR and AVRStudio tools to build programs. You
should be able to use C to develop microcontroller functions such as: Port Inputs
and Outputs, read a joystick, use timers, program Real Time Clocks, communicate
