PIC and 5110 Interface with SPI hardware – PR3

September 26th, 2011 11 comments

This is the first “official” project I am doing with my PIC prototyping board. This project is about interfacing and using a simple Graphic LCD. So to follow this project you need a PIC to have SPI hardware, in order to communicate with the device. The GLCD (Nokia 5110) I am using is well known in the community and it is a cheap device. I bought it off ebay for about 5 Euros. Read more…

PIC Prototyping Platform – PR2

September 7th, 2011 No comments

Hey,

In PR1¬†project, I talked about creating a stable prototyping platform that would save me from the trouble of setting up the microcontroller and all its required components. However, since then, I worked on tidying up this design into a more usable design (I wanted to play around with creating PCB actually ūüėÄ ). So I designed the board sent it for fabrication¬†and finally put it together. Read more…

Components for the Prototyping board arrived!

September 1st, 2011 3 comments

Hey guys,

A couple of days ago, the components for my new PCB arrived so I was able to test my design. The result was successful! Personally this was a simple board carries a lot of “firsts” for me. To begin with, it was the first time I ever designed a board on EAGLE that became an actual PCB. This might sound stupid but its different to make a design for home production (using chemicals) and a design that includes 2 layers, vias, solder masks, silkscreens, correct drill holes etc. I am not saying its hard, I am just saying its different so there are new things to consider.

Another “first” was the soldering of a TQFP package which as it turns out its not that hard (actually its like magic ;))! I had to buy some solder paste and a tweezers to make my life easier. I am suggesting to check out Surface Mount Soldering¬†guide if you are interested.

Anyway, for a first attempt, I believe the results are pretty good. I made a simple blinking LED program which works, the power switch and reset button work, so I am assuming the design is OK.

I will make another post soon to include the schematics and stuff if anyone is interested and hopefully start producing some projects on this proto board. Finally here are a couple of pictures of the board:

Looking good!
