I think it's the routine of the usblyzer! but I think there should be no difference between multiple times of pressing a specific button on the hid-demo.exe....
2- yeah!
3- yes, you are right.
3a- really?! ooooooooooooohh

I really APPRECIATE YOU VLOKI. thanx again.

Of course there should be no difference.
The first response should be the 0xF0 and then the 0x7...

BTW:
There is an ERROR in my code - should be ToSendDataBuffer[2+i] = packet_num;
Please correct this first if you not already did and see what happens.

I know; the "0x20" after the 0x71, 0x72,... will be omitted.

Of course there should be no difference.

so what's the reason of the difference?

my code for the PC_side was correct. now I can send and receive data properly.

Code: Select all

case CID_EEREAD:  //data from eeprom to pc
         for (int packet_num = 0; packet_num < max_packet_num ; packet_num++)
         {
               io_result = hid_read(connected_device, inBuffer, 65);
               for (long int count = 0; count < 65; count++){
                  long int numm = count + packet_num * 64;
                  my_store[numm] = inBuffer[count];
               }
}
         myfile.open("file.txt", ios::out | ios::binary);
         for (int ii=0 ; ii < 600 ; ii++)
         myfile << " " << hex << int(my_store[ii]) << endl;
         myfile.close();
       break;

Hi @vloki, I'm using revision r4 of your HID firmware (PIC18F4550 XC8) and the application in Qt Creator. Working wonderfully might i add.

I was wondering if it is possible to use and send more than one ADC value from multiple ports and how? Tried to figure it out from the firmware but figured that if you can only use one channel at a time, you be restricted to a single port?

Thanks.

The demo shows a basic communication only. Of course you can modify it to your needs.
How many channels and at which sample rate?

I probably would set up ADconversion based on a special event trigger that fills a buffer.
The buffer could be send like susi's EEPROM data from above ...

Hi vloki.

I'm trying to compile your HID firmware r4, and I get a "conflicting declarations" error for variable _INTCONbits:

Do you have an idea where could be the problem?
I'm using XC8 v1.37 with PLIB installed.

Thanks a lot

The libraries are worthless now with newer versions of XC8 because
some "cleanups" in the newer versions header files

Hi Vloki,

I am using LPC_FSUSB-CDC-X-r3 code for my project using 18f4550 in MPLAB-XC8. It compiled with out any changes. I am monitoring temperature & pressure variables. They are to be updated periodically in GUI. I compiled your serial commn code as it is. It is not compiling, with message "The build directory needs to be at the same level as the source directory". Please tell me what has gone wrong.
