thanks terry, i will try it ..
this MLK is for which processor ?
but i don't understand .. you write x1008 and x1000 ..
are these the adress of the interrupts ( hig & low priority ) vectors ?
if yes, why it's not x1008 and x1018 ...?
Code: Select all
//ROM MEMORY for Boot Loader
#pragma SetPage(PAGE0, 0x001008, 0x7FFF) // <----- add only for boot loader version
#pragma SetPage(PAGE1, 0x001000, 0x7FFF) // <----- add only for boot loader version
and in the interrupts code, why it's not x8 and x18 ...?
Code: Select all
//INTERRUPTS
#pragma SetInterrupt(I0,0x000008,0)
#pragma SetInterrupt(I1,0x000000,1)
i will try it now, back in some minutes ..
thanks

well i try this setting :
Code: Select all
//------------------------------------------------------ stuff for bootloader
//ROM MEMORY
//#pragma SetRomSize(131071)
//#pragma SetPage(PAGE0, 0x000008, 0x1FFFF)
//ROM MEMORY FOR USB BOOTLOADER
#pragma SetRomSize(131071)
#pragma SetPage(PAGE0, 0x001008, 0x1FFFF)
#pragma SetPage(PAGE1, 0x001000, 0x1FFFF)
//INTERRUPTS
#pragma SetInterrupt(I0,0x000008,0) // original setting
#pragma SetInterrupt(I1,0x000018,1) // original setting
//INTERRUPTS FOR USB BOOTLOADER
//#pragma SetInterrupt(I0,0x001008,0)
//#pragma SetInterrupt(I1,0x001018,1)
//------------------------------------------------------
same result .. my test LED blink ONLY IF ALL interrupts are commented ..
if i add some interrupt sub routine ( even with only "nop" inside) or try to enable some interrupts ( INTCON register ), the test LED blink will not work any more ....
do you have already play with interrupts when you use bootloader ?
thanks

Yes, I use interrupts in my code. They drive the entire program. USB I/O, blinking LEDs, Servos, scanned switch matrix. You name it.

PIC18F4550. I haven't tried this with any other PIC so you may have to adjust it to work with yours..

Please Terry,
can you share us a succesful compiled program with interrupts and configured to be upload by the bootloader ? just the ASM file ..
i would like see how the assembler work .
thanks

Hi!
We strongly encourage our users to switch to
mikroC PRO for PIC version because non-PRO version is an ancestor of PRO compiler
and is no longer being developed. Every new feature, improvement and bug fix will only affect new versions of PRO compilers.
If you're a registered user you'll receive PRO license key free of charge.
See the migration document for more details:

Currently, we don't provide HID Bootloader but it is in our near future plans to provide one.
For the time being you could use Bootloaders distributed with our compilers:
...\Program Files\Mikroelektronika\mikroC PRO for PIC\Examples\Other\Bootloader\
together with the USB UART Boards:
