Hey all,
I'm hoping someone can help me with a few things.
As a project I'm trying to create a braille reader as a project for school.
I'm using a PIC 18F452 chip . which will be connected to a PS/2 keyboard.
The chip will take the hex codes from the keyboard, and output the corresponding value to 6 electric solenoids or servo motors which will push the corresponding pins up or down.
Pyroelectro has a tutorial on how to connect a ps/2 keyboard to a 7-segment LED display
http://www.pyroelectro.com/tutorials/ps2_keyboard_interface/index.html
I just purchased a 16-segment display in order to be able to view all the letters that the 7-segment cannot, like the letter K, or V or W and so on .
according to their code, they use the RD outputs only

how can I configure the code to use RB and RC as well? As I'll need to use 9 more outputs.
Also, how can I change the code so it will drive the 6 different solenoids?
These are the solenoids I just purchased:

Any help would be great
Thanks
