CHEAP board houses?
Does anyone know about any board houses "PCB manufactures" that make boards at low cost boards in high volume. I'm making "learn how to solder kits" for my electronics teacher and I need to buy in bulk at low prices. If you see this brad, where did you order these boards from in this video? http://w...

PIC TETRIS/inverting pulses
Okay, so i've just finished building the PICtetris game from digital diy and I'm trying to make some modifications to the code. I need to send negative pulses to the columns of the led matrices. Right now the code is set up to send out positive pulses. Does anyone know how to invert pulses in swordf...

Setting the pickit 2 up with Swordfish
Im just getting into swordfish basic and need a little help setting it up. I have the pic kit connected to my pic chip but nothing happens when i hit the compile and program button.
Is there a special way to set up the pickit 2 to work with swordfish basic?

Adding more games
I noticed on the tutorial there were a list of games you could put on the game system. But my questions is can you put them all on? or maybe just a few? :D I was thinking that it might take up to much room on the chip so i don't know. :? If its possible to put more than one game on the game system, ...

Code misunderstanding
Could someone please explain to me what the numbers after each bsf/bcf command represent. Thanks draw_ball ; this routine draws the ball on the screen movf ball_y, w ; copy our ball_y co-ordinate to w movwf PORTB ; and then to portb (our data bus) bsf PORTA, 2 ; now latch this 8-bits to the green 74...

Re: Inverted pulses to led matrix
UPDATE: i figured out where to put that little piece of code. It was kind of a no brainer.
Thank for your help. Now i can start working on adding a second player.

Re: Inverted pulses to led matrix
I see how that little piece of code works but i just dont know where to put it, im still a n00b at programming.
I'm guessing somewhere in the draw_paddle or draw_ball subroutine. Could you maybe give me a hint to where it should go.
Thanks

Inverted pulses to led matrix
Okay so i just got done building the 8x8 game system and i noticed a few problems. Ive only uploaded pong onto it for right now. The problem is it looks like the 8bits being sent to the display are inverted like instead 11110011 it comes out as 00001100 i think. The first picture is what the screen ...

Re: inputs on the 74373
Now what about the connections from the 74373's to the led matrix. There arnt any pin numbers or notches on the 74373 in your newer/better schematic.

Re: inputs on the 74373
I think i found out how to connect the 74373's to the pic. It took some time because there are no individual connections in the schematics, its just data buses.
Im guessing that pin 13 of the pic chip connects to pin 3 of the 74373 and 12 to 4, 11 to 7 and so on. Can someone verify that?

inputs on the 74373
I was reading the 8x8 game system modifications topic it brought up a few questions in my mind. Brads newer/better schematic for the 8x8 game system only shows where the outputs of the 74373 go to the led matrix. Im trying to figure out how to connect the inputs of the 74373's up to the pic chip. Th...

Re: Two player pong on 8x8 led matrix
Hello again Surprisingly, i made some progress with this project. Ive been so busy with work and school. I have a circuit that can move a paddle up and down the matrix with a potentiometer. I followed brads adc with digital ports to do that. Now im just trying to interface what i have right now with...
