Hi Ober,

i had try the mouse source code and i facing some error when i build all. Kindly advice.

Er... most of the missing are from C18 Compiler. Try to search the header folder of MCC18.

hi,

for my installation, i found the file in C:\Program Files\Microchip\mplabc18\v3.37.01\h
u should be able to find in some similar directory, u should check how the file is included in ur c code.
isit by specifying the directories?
u can delete the path. and directly #include "file name"
u copy all those required file into ur project directory
then u will sure find it.
or else u will need to set the include search path from project setting.


regards,
yh

I have succefully build the Game Console and mouse functioning. Is anybody can teach me how to convert to Keyboard function? I just would like to make it able to key in something in the notepad.
I have search around the net, but they don't have comprehensive solution. It is better can provide the main.c, USB_descriptor.c, USB_config.h...etc.

Hi, actually Microchip also provide the keyboard USB framework on its site for free. You try replace your PR26 usb_config.h, usb_descriptors.c and main.c files with attached files. Then build it and load your program to your PR26. When you press Button 1, some characters should be sent to your PC.

CODE: SELECT_ALL_CODE

if(b_1 == 0)      // test button 1
        {
           //Load the HID buffer
           hid_report_in[0] = 0;
           hid_report_in[1] = 0;
           hid_report_in[2] = key++;    // ASCII
           hid_report_in[3] = 0;
           hid_report_in[4] = 0;
           hid_report_in[5] = 0;
           hid_report_in[6] = 0;
           hid_report_in[7] = 0;
              //Send the 8 byte packet over USB to the host.
              lastINTransmission = HIDTxPacket(HID_EP, (BYTE*)hid_report_in, 0x08);
   
            if(key == 40)
            {
                key = 4;
            }
        }

Under void Emulate_Joystick(void) function, you can simply change the sending character by replace the "key++". ASCII table, http://www.asciitable.com/

Hi A380,
Thank you for your prompt response!
I have followd your way to modify the code from Joystick, it builded failed. Nevertheless, i tried the .zip file you uploaded, it shown the same faliure as well.
Error [1105] symbol 'lastINTransmission' has not been defined
Error [1105] symbol 'key' has not been defined

Can you tell me how to define the 'lastINTransmission' and 'key'

Thanks!

Hi,

Sorry.. Try again with attached files now.. I tried it, compiled successful.

Yeah!! it work well, now let me try feel ASCII code and see..
But weird thing is..
I follow the ASCII code put "0x35".. but it come out "' ' "
then i put "0x38... it come out " / "
how come is it not come out number "5" and number "3"?
it is enuf.. i can figure out it.. as long as can get input from the PIC18F2550 then I happy d...
Thank you very much!!

Thank you!!

Hi,

Glad to hear that. Sorry again, USB keyboard should not refer to ASCII table.. hahaha.. should refer to this table, http://www.usb.org/developers/devclass_docs/Hut1_11.pdf page 53 under "10 Keyboard/Keypad Page (0x07)". "Usage ID (Hex)" column is what you need.
