Look at the datasheet again on page 42. There is a line on page 41 The RA4/T0CKI pin is a Schmitt Trigger input and an open-drain output. pay attention on underlined text Wink

I had the similar ...

Start first with:

#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8,stream=PORT1)

And then with something like:
printf("AT");

And finally you have to catc ...

Thank you for your answer. And yes basic concept is good and it actually work.

But (yes there is an but), I'm not satisfied with output accuracy. Problem is with my method of elimination for pres ...

Hi!

I need sanity check in this function. (I have no hardware yet, but I'm writing the code in advance.)

What I want to achieve is to simply pass the required frequency to the function and funct ...

I usually put 12pF capacitors there. But It should be tested for yor application.
On other hand, you could use [url=http://export.farnell.com/ael-crystals/c40m000000l001/resonator-ztt-40mhz/dp/14481 ...

Why don't you use opto-coupled triac driver with zero cross detection like MOC3061.

All problems with cross detection are solved and you have only to deal with the logic part of problem. :w ...

Here [url=http://melabs.com/resources/articles/ledart.htm]LINK you'll get the idea how to connect 7 segment led displays.

And look at here: http://www.ccsinfo.com/forum/viewtopic.php?t=39731

Thank you for that and rapid response! Cool

I bow to the master!
Thank you ... as I said I was caught in a loop.

Do you have a good title to read about I2C spec?

Hi all!

I'm trying to communicating between two PIC's with I2C protocol and I'm having troubles...

Circuit is simple as it is could be. Two PIC16F886 each have LCD connected on portB, SCL and SD ...

Are you deliberately using USB HID mode? Why don't you use CDC mode?

If you don't want to bother yourself and uC with USB communication, then it is easier to take some of UART<->USB chips available and let them do all the work around USB stack etc.

Now here is ...

bkamen: Neither...

I'm working on digital workbench power supply. It will be two channel that will be electrically separated, so you can then connect them together for dual operation. One PIC will ...

Thank's for all replies. I'll test I2C and uart and I'll see the results. Thank you for this brainstorm. Cool

Thank's for reminder....

Data from slaves will be sent twice per second, packet will be 8bytes long, communication speed will probably be 28kbps. I didn't consider SPI or I2C because PIC's will be ...
