This is more like a quick reference for myself, how to pass a method as a function argument. It turned out to be very useful for one of programming tasks. I had a lot of "get" type methods with the same return value, and needed to construct a table of results. And passing method as argument, was a very neat solution.
Out of boredom I figured out I'll write a library from scratch to interface the character LCD display which I got from ebay, quite cheap. Less than 7 pounds. However, I have written before a simple code to interface an LCD from scratch for 8051. So I have some experience and understanding how the character LCD works. The difference now will be, I' ll be using 4 bits, instead of 8 bits to communicate and read the busy flag. Essentially improving the previous code. I chose to write it for Arduino this time, because I have Sanguinololu bought for my 3D printer, and at some point I want to write a LCD user interface for it, from scratch. There won't be anything spectacular about this tutorial, there are already good articles about this stuff for all kinds of devices. Moreover, arduino has bunch of LCD libraries available for download for free. BUT... in this tutorial I'll describe problems I encountered and try to be as descriptive I can be so you can understand how the character LCD works, making you able to interface it with any micro-controller available, and even driving it by hand.
At the begining I thought I'll need to send text only through email. But the more I thought about it, I understood that I want to add three files to the mail as well. By altering previous code I managed to add simple Multipart MIME message support. In other words file attachments.
For one of my projects I wanted to develop a crash reporting dialog where user can enter the steps he did to crash the application and then by pressing send button the app automatically will send me user report and the log to my e-mail address. Unfortunatelly Qt doesn't have a Smtp library, and I don't want anything heavy just to send a simple string of characters through gmail smtp server.
One of my favourite applications when it comes to learning, that is revising is FlashQard.
FlashQard is an educational software to improve your learning process. It is designed to help you learn not only a new language but anything that can be learnt!
This aim is achieved by using the widely used method, called Leitner System, and the idea of "different card types for different purposes".
Leitner System (proposed by Sebastian Leitner in the 1970s) is one the most efficient methods for learning. Which allows you to focus on the most difficult flashcards and not waste your time on what you have already learnt.
Very good writeup. I thought had been fighting my code for a week or two and confirmed what I was dooing was right. This overview is the best I have seen for doing the code. You may wish to add one thing though that I have found on another website. Urge people to check the contrast dial on...
Start with reading about C language, proceed to reading about Arduino platform/ide proceed to reading about i2c bus proceed to reading about adxl345. Rather not the other way round, although that's probably also possible, but it will be more demanding, as you have already...
