Hello Ben,

Yes that does work prerfectly, but I would prefer to declare the variable in assembler. Is that possible?

Cheers,
Bert

I want to define a variable called asmtest in asm. I thought I could do this in a C block (for an 18F4455 PIC):

asm{
asmtest equ 0x00000006
// rest of the asm code
}

But I get a syntax error. Could you tell me what the proper syntax is please?

Cheers,
Bert

Ah, this works perfectly, thanks Sean.

I have a macro is called Mtest, with a local variable called Mtest.VarTest.

So in a C-box (in that same macro) I would expect this variable to be called FCV_MTEST.VARTEST but that doesn't work. What would be the proper syntax in this case?

Cheers,
Bert

Hi Ben, Thanks for your reply. I still get an error message: Launching the programmer... C:\Program Files\Matrix Multimedia\Common\PPPv3\PPPv3.exe -cs 2 -nogui "18F4685test.hex" Sending program... Erasing the PICmicro Writing program memory .. Writing configuration memory Programming failed: <8><10>...

The EB006 / PPP will not program an 18F4685 pic. If I take the HEX file gerenated by Flowcode and use a different programmer (the Wisp648) it programs just fine, so apparently the HEX file and the 18F4685 are fine. This is a part of the output file from PPP: C:\Program Files\Matrix Multimedia\Common...

Installing .NET runtime seems to solve the problem.

Thanks again for your quick reply!

Bert

Thanks for your quick reply. The driver now installs without warnings but mLoader.exe still won't start.

Maybe I should download the updated version of Flowcode for ARMs and try it that way?

Bert

I have downloaded Flowcode for ARMs from the website. Installation went fine until the moment that the programmer software was to be installed. I received this errormessage: "The current language is not supported by the Device Driver Installation wizard. Contact the vendor that provided you this pac...

Ok, thanks Ben!

One final question: I noticed that the libraries eeprom.pic18.lib, flash.pic18.lib and adc.pic18.lib are not present in the Flowcode boostC library directory (as opposed to the pic16 versions that are present in that directory). Can they be downloaded separately?

Bert

Thanks for your quick reply Ben! This works perfectly.

Can I leave the random library in the compiler options list or will that have a negative inpact of some sort on other projects?

Bert

According to the boostC manual srand() and rand() are valid functions, but this c-code block fails: srand (FCV_RANDOM); FCV_RANDOM = rand (); with list of errors, including srand and rand being unknown: C:\PICflow\projecten\lopend\Random4.c(384:2): error: unknown identifier 'srand' C:\PICflow\projec...

Great, thanks Ben!

I now do this to get two numbers out of the string (for example "64"):

number = ( string[0] - 48 ) * 10
number = number + string[1] - 48

Is this the preferred way or is there a smarter command?

Bert

I have a string which contains "6" and I want to convert that string to an integer (or byte) so I can use it in a calculation. Which command do I need to use?

Bert

Thanks, I'll take a look at that. The helpfile for this component (custom.hlp) doesn't seem to exist (at least not on my harddrive). Can you point me to a download link?

I will check out the C manual, I didn't even know I had one

I want to toggle bit 0 of the OPTION_REG register with asm, like this (entered in a C-box):

asm
{
BTG _option_reg, 0
}


but for some reason it gives an arror and won't compile. I think this is valid Microchip assembler. Any (asm) suggestions how to get this to work?

Bert

Has the VB5 SDK been released yet? I can only find an SDK for V2 but I assume that won't work with V3 (in fact I suspect it won't work for any version because the module1.bas file appears to be missing).

Bert

After hours of messing about with settings and Ethereal, which is now called Wireshark btw, I finally found the problem. In the pdf that came with the E-block it says that the ipadres of the networkcard needs to set. The instructions say that you can use ipconfig the find out the current ip address ...

I'm testing the EB023 block with the testporgram and setup from the small CD (EB023_test.hex). When I switch on the programmer the program says "Starting up... completed" as it should (this only takes a fraction of a second). The "cable not connected" icon disappears from the tray so it would seem t...

Is the file format of the .fcf file available somewhere? I want to use an external program to write this file (sort of like pre-processor) and then continue working on it using Flowcode itself.

Bert

Thanks Steve, that did fix it.

Nevertheless I still would expect any asm statement added in a C box to be carried on to the asm file. Why didn't that work?

Bert

I use an Xwisp programmer which assumes the fuses to be in the hex file. In my program I've added a C box at the very beginning of the program with the following content: /* fuses asm __config 0x3f32 */ While downloading the programmer complains and says it cannot find fuses in the hex file. I don't...
