Problem with Borland Builder 6

[yolanda1]

Hi

I make this code in Builder 6 :
//******************************************************
HANDLE h_read,h_write;
DWORD qty,nbytes,result,millisecs,tlen;
unsigned char data[3];
boolean closed_ok;

qty = MPUSBGetDeviceCount("vid_04d8&pid_0011");
Form1->Memo1->Lines->Add("Founds " + IntToStr(qty)+" Devices");



h_write = MPUSBOpen(0,"vid_04d8&pid_00011","\\MCHP_EP1",0,0); // Write
h_read = MPUSBOpen(0,"vid_04d8&pid_0011","\\MCHP_EP1",1,0); // Read


if (h_read != NULL){Form1->Memo1->Lines->Add("Open by Read OK");}
if (h_write != NULL){Form1->Memo1->Lines->Add("Open by Write OK");}



millisecs=1000;
data[0]=0x01; // led mode
data[1]=0x02; // 0= leds off

nbytes=0;
tlen=2;
result=MPUSBWrite(h_write, &data, tlen, &nbytes ,millisecs);
Form1->Memo1->Lines->Add(nbytes);
Form1->Memo1->Lines->Add(result);

closed_ok=MPUSBClose(h_write);
if (closed_ok== true){Form1->Memo1->Lines->Add("Closed by Write OK");}
closed_ok=MPUSBClose(h_read);
if (h_read != NULL){Form1->Memo1->Lines->Add("Closed by Read OK");}
//***************************************************************

All work Ok, except MPUSBWrite() function
result and nbytes allways = 0.
This indicate function not work

Need help by solve this

OK folks... this is getting absurd!

I seems this board has shifted from CCS C to C18 to VB
and NOW Builder 6.

When are we going to stop this and get this board back to stuff related to CCS C where it belongs ...?

Before long we will be doing projects for all comers on any language or hardware!! At one time we basically didn't do school projects for people from scratch but it has gradually shifted further and further in that direction.

I for one feel this board needs to stay on topic as a CCS C Programmer resource and not a become place to get your school project done for you!

Time was when we found it was a school project or NOT CCS C we told them to go elsewhere and come back when they had some CCS code that needed to be debugged.

Hi guy

Wath is you problem ?

This is a forum or not

Yolanda

[SherpaDoug]

It is a forum for the CCS C compilers for PIC microcontrollers. It is not a general C programming forum.

Ok well

And this post ?

The way I see it, anything related to CCS, PICs, hardware connected to a PIC, and even PC-based software that is supposed to work with a PIC (e.g. USB host software) is fair game here.

Hi

Thanks Mike

Single I need a little aid

[dyeatman]

[J1M]

please dyeatman read this:


General CCS C Discussion
General discussions related to using the CCS C compiler in your Microchip PICmicro MCU designs. Also any discussion related to embedded systems programming and design.


"Also any discussion related to embedded systems programming and design."

Yolanda has a problem with PIC Programming DLL by microchip, and its in topic of this forum.

Next time, my dear friend dyeatman, please, simply shut up, and dont reply this way.............................................

regards.

Isn't it amazing have p.ss.d off some people get when others ask for help on RELATED topics. If you can't help, then don't answer the post, but don't throw all you toys out the cot. This is directed to Mark (remember the snotty comment CDC incident), dyeatman and SherpaDoug - You guys might be experts at everything related to Embedded control, pics, programming, PCs, electronics , life the universe and everything, and we respect you for that; but you must remember that the rest of us are not?

So please let the rest of us non-expert little people help one another as best we can.

I see it this way....

Somebody comes along, looking for a 'C' programming forum. Reads a bit about what is discussed here and realizes that there are some pretty smart people here (myself excluded ). Without knowing that it is a fairly specialized forum, he posts a question on a topic that he desperately needs help with, hoping that somebody here will have the answer.

Now, with all of the vast knowledge that cruises this board, somebody will probably answer his question. If the 'cry for help' just happens to not be 'in topic', sometimes somebody that is having a bad day or simply stepped in a pile of dog crap might decide to vent his frustrations out on this innocent person that is asking for help.

There are, however, many good people that frequent this board that will answer whatever question they can whether it is 'in topic' or not. I, myself, have asked questions that don't pertain to PIC's but other types of hardware problems. Luckily, many have been kind enough to help out if they know the answer.

People will visit this board without the full knowledge of what it was intended for and post a question. If it shouldn't be posted here then the proper thing to do is to 'nicely' explain they are in the wrong place and allow them to leave in peace without being burned at the stake. Even an occasional Russian posting can present a humorous moment for many of us 'cubicle slaves'.

Darren was trying to be nice when he wrote that statement.

The C18 stuff is definitely an abuse of the forum. Someone gets
a free compiler (for a while) from Microchip, and then he doesn't
like their forum, so he goes to a competitor's and uses it instead.

It costs CCS money to keep this server going. We actually pay
for it with our yearly maintenance payments. So the C18 people
are actually ripping us off.

Mike V., if the forum went the way that you say in your post, the
huge number of students that just went back to school in September
would turn this into a non-CCS forum very shortly.

Darren was intending to be nice. I don't think he intended for CCS
to become a student's general resource.

I suscribe 100% rnielsen comments and point of view.

This recurrent discusion had been present in this forum lately, I also remember
the time when we discussed the way to split this forum into different topics.
Lately beginners questions had populated this forum asking all kinds of basics C
related questions. This is not a minor issue, this feedback has a direct relationship with
the amount of students using CCS compiler in different teaching levels.
If CCS deliver a Compiler packet targeted to students and beginners, it is not the time
to open a new forum to give some helps to them ?

I see now how my previous comment might encourage this forum to turn into a chaotic free-for-all.

I think the frustration here has a lot to do, not with the students returning to school in September as you said, but rather the summer school students who are screwed with only a few days left in the summer term.

I don't know what they've learned all summer long, with 1-2 weeks left to complete (or in other words, "start") their semester-long project, they apparently don't know the difference between CCS and C18 or HT-PICC. So they troll here and at the Microchip website's forums hoping to find someone who'll write their code for them.

You can smell such desperation and immaturity a mile away. That's different from the inquisitive individual who already has their PIC-based USB device working, and wants to be well-rounded by asking about supplementary texts to write the corresponding PC-based host USB code.
