try using another version of micro c if this error appear again
if you can send your project files , i will try to compile it

Put a delay about 200ms in do-while loop and try

open c:\program files\Mikroelektronika\mikroC PRO for PIC\Examples\Internal MCU modules\p18F4550\HID Read Write Test

you will find VARs.h and Definit.h copy and paste them in your project folder

Thank you alot yt7pwr. I can now send and recieve data using hid terminal of mikroc . now i tried to use a bootloader , i installed MCHPFSUSB then C:\Microchip Solutions\USB Device - Bootloaders\HID - Bootloader\ then i programed my pic to USB Device - HID - HID Bootloader - C18 - PIC18F4450.hex fil...

Sorry if I missed this info- I scanned the thread but didnt see it. Donot worry at all .Thank you alot for your reply wooooooooooooooooooow my code is now working i put some delays in the loop as you say and it works excellant now . thanks alot but when i send 1 the Ic writes to me AAAAAAA .i want ...

Try example "Hid ReadWrite test" in example folder. If that dont help try MicroC Pro compiler version. thank you alot for your reply I have some questions what exactly this function do ? HID_Write(&userWR_buffer, 1) if it takes one byte from the buffer as random? or the first byte only userWR_buffe...

Thank you alot.
but when i use ur code this message is appear again


do you thing that is from the configurations ?
if yes , what configrations do you use ?

Post your code hard to say with out your new verion of code this is an new code program usb18f4550 include USBdsc Dim k as byte Dim userWR_buffer as byte[64] Dim userRD_buffer as byte[64] sub procedure interrupt HID_InterruptProc end sub sub procedure Init_Main '------------------------------------...

I am also new to all this HID USB stuff However if you are using the dsc file from the mE example I expect that it has speciied the In and out report lenghts as 1 and you are sending 8 make a new dsc file and specify the IN and out lengths as 8 use a new VID to do this as long as you use the applic...

I think your Microcontroller is not runnig or you have an error in your USBdsc file . did you generate the descriptor file to suite your In and output report lengths did you enable the USB regulator in the configuration Thank u alot for your reply my microcontroller is running because when i put th...
