Hi
I have made a solar charge controller 5 years back but I have the code with me still somewhere I feel. It was done using 16f72 as far I can remember. Please let me know if you need that.

rebooted the laptop and the LED's are there??? Dont know what to say???

Don't really understand what you mean?

In the additional files Flowcode code is given..you should be able to find that.

Yes, it's always nice for a beginner to follow ready code which will orient you with tips & trick as well as basic programming techniques.

Yes. You are right. In the above code it should be 0.000244 instead of 0.000976

Hi
Can you please try this post of Martin? This is simple and easy to test.

Yes, you have to uninstall previous version..Glad to know it is sorted

I was wondering what were the advantage of those 2 programs over the simple program dazz made? (I need to show 0.5,1,1.5,2,2.5,3.....) I have mentioned the advantage in my last post..you can't accommodate float data manipulation in small memory chip. And i got one more thing when i simulate it, it ...

Hi
I believe this figure will help you in finding whether any pin spare or not...It seems PORTD is connected to DB9 for EBlock interface which I guess can be used to interface any external sensor easily if not restricted in boot-loader.

Basically I want to add a temperature sensor to the buggy. Ideally onto an analogue pin, but if none available then a simple temp high/temp low, through a digital input pin and external circuit. You can interface DHT-11 with buggy which will not need to be interfaced in analog pin rather any I/O pi...

Your Flowchart compiles fine for me as well which means you need to move to V5 professional for this as Martin said.

Yes, Martin is right. These could be gathered in a handy Eblock. Good findings Stuart

Hi,
You can post your code if that is not commercially sensitive we can see what compiler is saying! May be you are right about Home version as that is not for extensive work.

Did you mean a delay in an interrupt or delays that happened whist interrupts are in background? I do the latter but not the former. I have talked about former one. Can a v5 file be opened with v3 because that might be one way to restore it to working again? No, but you can make your own code in V3...

Hi
If you call any component macro inside the interrupt it will cause stack corruption..Please avoid to use delay and LCD macro which uses delay in any interrupt.

Thanks for letting us know by an organised post

Your PPPv3 seems latest and code config seems perfect. It's strange that EB006 is causing issue. Have you tried to detect chip like 16f877 whether it detects or not?

Here is FCD with GP2INT

If that is RB0INT to GP2INT change, it can be done by FCD. I have done that earlier. Frank please confirm that if you want I can do that for you

Before deciding maybe best weighing up pro's and con's so you know which is time best spent on first.
In the end both types have their different uses, but in different applications.

Yes, you are 100% right and that's the reason why I am interested to buy to find application.

Hi
I think you are using old version of Flowcode v4 as you are using V4.2 whereas V4.5 is the latest version. Can you please try to update your version and see the issue again?

The code is big as we use float and string and related calculations..we can get the same without float. I will post that

This code is large for this chip but I can tune that to fit in this chip if you don't have any other chip

Hi I have used the same trainer for my student and now the code can be re-written very easily..but for your problem you need to check couple of things like.. 1. which version PPPv3 you are using? 2. which version of Flowcode you are using? 3. You can PM me the program as this is commercial version p...

What do you make of the manual ?
I think it has loosely been translated from Chinese LOL !

The Chinese supplier send me doc copy and I just made pdf...might be pdf converter made to Chinese
