I have a very basic knowledge of electronics and maybe even less of programming. For school projects and for fun, I have been working with my arduino for a while now. I can write some simple functions and make my arduino do what I want if I want to. But I am not so familiar with more complex programming and for example with shift registers and other IC's.
Right now I am building a very large 3 digit 7 segment myself. It is a very large wooden box with a single red LED for each segment of each digit in it. So it consists of 21 LED's. I have got my hands on 2 tlc5940's yesterday. From my research on the arduino forums and the wide capability of these chips. I thought it would be a nice idea to start using them with a simple setup like this one.
What I would like to do is to use these digits for the time being as a counter. So I would like to send the TLC's a number and want the number to be displayed using the corresponding LED's.
Now of course, as I explained before, I am good in building stuff, but not so good in understanding and applying the C language. After taking a long&long look at the TLC5940 library I am now totally confused and really don't know where I should start with the programming.
I do have some basic questions for example, - How do I address each LED in my sketch while using the TLC library? - How does this whole system of libraries work? What do I have to change in which document inside the library folder in order to set my chip up correctly.
I know already that I can actually use simpler chips such as the 74HC595 but i want to take on the challenge to learn to use the TLC for possible future projects.
I would be more than happy to hear if somebody could at least point out a direction for me to start from. My main problem is that I have no idea as to how I should work with this library and for example which commands I can use and where they are listed.
