8×8 LED matrix using PIC16F690 microcontroller
8×8 LED matrix
I’ve added a pattern generator to create patterns but not all of it’s features are complete
-8x8LED matris (can make one but i bought mine)
-8xNPN transistors (I used C547B)
-prototype board (or you can make pcb for this)
-5V power supply (you can use a voltige regulator but I just power mine from a usb port)Tools:
-PIC programmers (all the pic programmers from microchip exept for pickit1 will work)
-Software- MPLAB (free software from microchip)
-A vacum pump for removing solder is good to have
-wire cuttersSkills you need:
-soldering skill (being capable of making good solder connections within 5-10 sec.)
-Logic thinking to some levelIf this is your first experiense using microcontrollers I recommend that you start with a more simple project.
Step 3: The code.
NOTE the letters in this code may display in reverse sense I accidentally reversed the ground in my display.
Step 4: Editing patterns displayed.
to add a pattern simply generate the pattern with the generator that is included in this step….
It is a .rar file so use winrar to unzip it.And yet agin I want to thank portreathbeach for having the source code of the genorator in his document about the www.instructables.com/id/3x3x3-LED-Cube/to make a moving design you can few steps to the subroutine and it will be like this.
