interrupt handler (Interrupt at 0x0008) error for USB code

[arvinfx]

Hi I try to check mikrobasic sample code for USB in PIC18F4550
I exactly copy and paste the code in help file of mikrobasic but HEX file not generate . please find the code and error message blow:

Code: Select all

program HID_Read_Write_Interrupt

dim cnt as char
dim readbuff as byte[64] absolute 0x500           ' Buffers should be in USB RAM, please consult datasheet
dim writebuff as byte[64] absolute 0x540

sub procedure Interrupt()
   USB_Interrupt_Proc()                           ' USB servicing is done inside the interrupt
end sub

main:
  ADCON1 = ADCON1 or 0x0F                         ' Configure all ports with analog function as digital
  CMCON  = CMCON or 7                             ' Disable comparators

  HID_Enable(@readbuff,@writebuff)                ' Enable HID communication

  while TRUE
    while(HID_Read() = 0)
    wend

    for cnt=0 to 63
      writebuff[cnt] = readbuff[cnt]
    next cnt

    while(HID_Write(@writebuff,64) = 0)
    wend
  wend
end.

Hi,

Have you tried to run the project from the following path?
C:\Users\Public\Documents\Mikroelektronika\mikroBasic PRO for PIC\Examples\Development Systems\EasyPic7\USB\HID Read Write Interrupt

Kind regards,

[arvinfx]

Thanks , Now it is working!

Hi,

You're welcome.

Kind regards,

[arvinfx]

another same error happen in V7.5.0 .when i copy a project from another folder to a new folder ! why ?

for ex:

C:\Users\Public\Documents\Mikroelektronika\mikroBasic PRO for PIC\Examples\Other\Sound

I copy "Sound" to my desktop and run it , but compiler error is this:

Hi,

Does it happens if you do it with the "Export Project" feature? You can try it by pressing Ctrl+Alt+E in the compiler.

Kind regards,

Hi,

Unfortunately, I've not managed to reproduce the same issue.
Could you please zip and attach that project here?

Have you tried reinstalling the compiler (please install the compiler with administrator privileges, right-click on the icon -> run as administrator)?
Also, how have you run the compiler? Please run it also as an administrator.

Kind regards,
