ICD, ICSP and Picbasic Pro

[mwhatley]

Thanks Bruce and Robert. Since I posted the original post I have purchased the full MCSP package but I have not tried the ICD method again. I had assumed that what Bruce said was the correct method and no bootloader was required.

My original problem was that it worked fine on a sample program that I believe I got off the Rentron site. So I know the basic hardware was good. When I tried it on an actual project it would hang up after the first few executable lines - and not always in the same place. I don't remember what the project was now but I think the problems came during the initialization portion.

All my 'stuff' is at my office and when I get a chance I'll try the ICD again with the new MCSP.

Thanks again, Mark

Hi All,

Havent used the ICD feature before but this thread has made me take a closer look at it.

I decided that my current project will benefit from this as I currently have loads of code stuffed in there to try and debug what is happening but have realised that if I use ICD then I dont need it.

The problem I have is with this section of code

For CharCount = 0 to NameCount
Hserout [Name[CharCount]]
Next CharCount
Hserout [10]
Hserout ["IP: ",DEC IP[0],".", DEC IP[1],".", DEC IP[2],".", DEC IP[3],10] 'Display IP Address

The two lines in bold fail with the message "Bad Expression" but ONLY when I compile with ICD (CTRL+F9).
If I compile normally (F9) then it compiles without errors!!

Any ideas ?

Thanks

HSERIN/OUT commands opened up a Serial Window when I executed them in ICD. At first glance I can't see what is wrong with your code.

What about the HSER definitions in your program, what does that code look like? Baud rate, etc.

I believe that the ICD uses the hardware UART of the target PIC to communicate with MCSP. My guess is that you can't do both - run the ICD AND use the hardware UART under your program control. The complier is raising an error when it sees the HSERIN/OUT command when compiling for ICD use.

I suspect it's this line Hserout [Name[CharCount]]

How is this supposed to work? I.E. how are your variables/constants defined?

EDIT: Found the solution. Enclose all your array elements in parenthesis VS
square brackets.

For CharCount = 0 to NameCount
Hserout [Name(CharCount)]
Next CharCount
Hserout [10]
Hserout ["IP: ",DEC IP(0),".", DEC IP(1),".", DEC IP(2),".", DEC IP(3),10] 'Display IP Address

Works as expected.

Hserout [Name(CharCount)]

Works as expected.

Excellent. Thanks Bruce.

I also found out that instead of

For CharCount = 0 to NameCount
Hserout [Name(CharCount)]
Next CharCount

it would compile with a single line of

Hserout [STR Name\Namecount]

which would achieve the same result although "Namecount" would have to be one higher than in the For/Next example.

What I dont understand is why the ICD compile gets upset with the square brackets when the ordinary complier accepts it.

I use the following two bits of code in the same program which follow the same style and both of those are fine.

For CharCount = 0 to NameCount
Read NameBase + CharCount,Char
Name[CharCount]=Char
Next CharCount

For CharCount = 0 to NameCount
LCDout Name[CharCount] ' Boot message.
Next CharCount

It would appear that it is only a problem with Hserout because that command requires square brackets as part of its syntax.
Just tried Hserin with the line Hserin [Name[Namecount]] and that compiles fine with [] or () around the array element.

Mighty strange, will drop David Barker an email to let him know of the inconsistency between the two compiles.

(old thread, but hey, information is information)

I wouldn't be surprised if it had to do with this:

When in doubt, rummage through Melanie's and Darryl's old posts. They've discussed all sorts of obscure stuff over the eons.
