OK so you have a couple of big delays in there. If the data is coming into the UART faster than you are pushing it out then potentially you have a timing issue. Do you really need a 1.5 second delay in the middle of your UART code, that's a long time for a microcontroller. A better approach would be...

To coin a phrase, what's your budget for getting this done?

I develop Man/Machine interfaces for ROV's in the North Sea and this is straight forward work. Happy to provide you a working solution PM me if interested.

What is the error being given and can you post your code. Both would help diagnose the problem and are so fundamental to getting you some help. So easy to blame the library (which may not be perfect) but unless you fully post then how does anyone, especially the MikroE people, figure out what is goi...

Not sure you are correct but if it works for you with what you have done then good stuff.

Another happy camper

While you are waiting........ Let Google be your friend. Search "PIC USB MIDI Interface" and there are many many sites to choose from!

Good luck,

In both of your for loops, d never get's to be 1024 or 0 because of the test you are employing. Perhaps you should be doing something like this if you want 0 and 1024 to be values that are applied to your PWM: for(d=0;d<=1024;d++){ and for(d=1024;d>=0;d--){ Does that make sense?? Good luck M

I have read this post a couple of times and each time I think my response is the same. I think this is a call to MikroE to ask if they would be willing to share the source. I suspect not without a compelling business case but it's certainly worth a try. Gotta say that it's disappointing that MikroE ...

mikroC code is of course correct.

A very broad statement without posting the code.

It is simply impossible to answer your question with the scant information you provide. How about you post your perfect code and someone with a 16F877 might try and compile it to help you??

Good luck

Mo, Hope you do not mind I call you Mo, I have a very dear friend with the same name who has always liked Mo :D Your question on the surface is perhaps simple but deserve more of an answer. If you use the UART library then you are in effect trusting in the MikroE coding skills (and they are pretty d...

So I guess I should have asked whether you are using the modules on their own or are you using them on one of the evaluation boards. Judging from what you have sent you have some sot of complete/evaluation modules, that makes a difference. The power can have a wider range because all the power condi...

wuu, You have a heck of a lot going on in your interrupt, is there no way you could take some/most of that code out of the interrupt to make it as lean as possible. I would imagine that the code does not have to be identical between MCU's? Personally I think it as "best practice" to keep the ISR as ...

Couple of things: 1 Are you supplying 12v to the MAX232. Datasheet says Vcc of 6v 2 Are you sure that you have the zigbee modules wired correctly to your PIC Rx -> Tx etc 3 You have not posted any code so it's hard to know whether you have configured RS232 correctly for the Zigbee module 4 Datasheet...

How about you post the code you are having the problem with? Counting time with a timer and interrupt is certainly a good way of achieving what you want to do.

Glad you got there in the end.

Is your issue with making the RS485 library work or simply getting your problem/project to work? I would suggest that you could expect more help if you were to describe the symptoms, what you think the problem is and what you think might be the answer. A post of "Here's my project, what's the answer...
