microcontroller not working at all
12 volts? it doesn't take much over 6 volts to fry a pic. Read the data sheet.
When you try another pic use a volt meter to test you input and output to see if its working.

ttl cmos interface
voltage
Most ttl like the 74 hc als and ls are 5 volts some cmoss can be as high as 16 volts. So a current limiting resistor is needed.
Hello i_sen86
I program pic's so I can't help you with the programming, but I have made a couple of scrolling message signs. one was with 74hc505's and the others were made with cascading cd4017's. When I do it again I will use the 4017's there cheaper and the program is easier to write...
Re: led moving sign
Hello sanjaya75s
Heres a site that explains how the programming works.
**broken link removed**
I built a bigger one using 74hc595 chip and a pic16F628a. It worked but I think my next one I will use CD4017's instead. I already cascaded them so I don't think it will be a...

Hello zio_nneo
I tried to load Mplab 8.00 using wine with no luck, I think it has a lot to do with how the permissions are setup for hotplug. not sure> I tried posting my problems on the ubuntu forms with no replies plus a few other Linux site. I guess it is to complicated to...
Hello
Ya I mostly read the forms. I Learn more with my mouth shut.
You keep pushing the PICKIT-2 clone what about the icd adapter you need for debuggingr the low pin count pic's, like 16F628A & 48A's.
Hey look at me two post in one year. ah I should of used my other user name...
Hi
don't know yet but I'm going to read up on it, also I was looking at the bsf INTCON, PEIE mabe if I did this bcf intcon, rbif. Think thats the control bit for Portb interrupts.
I try it tomorrow and post my results.
added to post,
its tomorrow and I could not get the portb I/O's to...
pcb service for hobbyist
Hello
I think he meant A4 as the size of the paper. I was woundering what is and wear you can find Cupric Chloride?
Thanks

Hello
I have been studying different parts of a program in the simulator and on project board. I ran into something I don't understand. I'll post the code then explain the problem
;Timer1-s1.asm FOR SIMULATOR
; program to test timer1
LIST p=16F628a ;tell assembler what...
Hello
I don't know why blueroom is so hyped on his pickit 2. It cost more then Microchips Pickit 2. Microchip also sends a USB cable with the programmer,
that save about 10 us dollars and its in a case. Plus you get a lot of free software.
I have a Pickit 2 programmer there nice, with...
Re: PCB manufacturing
Best way is in the paper. I tried photo paper and it worked but was hard to remove from the copper. I tried magazine paper that worked and was easy to get off but I wanted something cleaner because I did not to ruin my printer. I went to Office gloss paper, it is clean and...
