So lately I’ve been messing around with alot of electronic components lately. One of these beauties is a 160×120 LCD screen. I will admit, they seemed a little daunting at first, but I was fairly surprised how easy it is using these LCD screens. From what I’ve seen thus far, special commands are executed by sending the hex value 0x7C followed by the proper command. For example, to reset the display, I just need to send 0x7C then 0x00. Of course, to add text to the display, just send an ASCII message to the display. I did not do anything with boxes or lines yet, but will be part of my agenda.
The last new item I used this week was a RFID ID-120 reader. Like the 160×120 display, it’s controlled via serial. Apparently, this item beauty was shown in Blidr, and the pseudo code for reading the RFID tag was very simple. In fact, I re-wrote the code to be used with the PIC18F4553, which I will post a tutorial on how to use it before I go back to RPI.
The picture above shows the tag of one of the RFID’s after I ran my RFID reader code on the PIC18F4553. It’s a little slow reading the tag at times, but I find it very reliable. Well, that’s it for me this week! See you guys on Monday….o wait. The world is gonna end today. Well, it’s nice knowing you guys!
