PDIUSBD12 PROBLEM

hi again
I solved that problem that I had with device descriptor
now I have another:D

I recieve new inerrupts when I'm processing the previus one & it cuases nested interrupts
how can I solve it ?
I disabled the interrupt when I want to process but by this I lost some interrupts
plz help me with this promlem
I realy need help
 

Re: PDIUSBD12 PROBLEM

If your processor isn't fast enough to process the interrupt before a new one happens, you don't have that many solutions.

1. You can try to disable unnecessary interrupts in the PDIUSB chip so that it generates less interrupts

2. You can minimize the code in your Interrupt Service Routine. Per example you can ack the interrupt in your ISR and set a flag so that you process the interrupt in your main loop

Good luck
