Re: A little HELP!!

Looks likely I can run a partial test on NTSC, I have found the appropriate crystal deep in the odd box, and I have the possible loan of a multi monitor, it is rather old but if it still works it...

Re: A little HELP!!

looks like it is bit 8 of control regester for NTSC

Search for %0000000011001110

Immediately below you will see gosub send, this points the chip to address 14

the next instruction is the...

Re: A little HELP!!

Wow! Looks Great! Would you know which bits to change? I ask since I was not successful with my previous program.

Thanks, Ed

Re: A little HELP!!

Hi,

I have compiled and programmed a 16f628a and it all works fine.:)

Pics a bit fuzzy due slow shutter.

Remember the code posted is the PAL version you need to change the bit(s) for NTSC.

Re: @ device ?????

I believe that is the syntax for setting the CONFIG bits when using the old, obsolete, PM assembler. If you have PBP3 you must change it the "new" syntax.
Find the .INFO file for your device in the...

@ device ?????

Hi!
I have seen Config and have never seen "@ device PIC16F628A,HS_OSC,BOD_ON,MCLR_ON,PWRT_ON"

Is this valid?
How do I change it for a 20MHZ crystal?

Thanks, Ed

Re: PBP registration does not stick, still unregistered

You may have let your "install window" lapse... I'd ask them for a new regcode, as long as you have proof of purchase. Let us know how that goes, because I may be in the same boat someday.

Re: Code interpretation

That was interesting.
The Tetris was monochrome for an LED board, so the Tetris shapes and the well were all arrays of bits.
To write the same thing in C inflates the program, but uses no more RAM....

Re: A little HELP!!

Hi, I have dug out some code I used for this chip, but it is PAL, you should be able to change the appropriate bit(s) to NTSC.

It puts the word TEST. on 3rd line at right hand side of the screen....
