Hi.
How can I simply disable interrupts (IRQ) on my ATSAM7X application? I simply want to prevent some critical HW-timing from beeing interrupted by "other stuff". Something like: ... disable_irq(); "PA1=0" // set 0 to a port "do some time-consuming instruction to ensure a fixed duration" "PA1=1" // set 1 to the port enable_irq()
I tried to include "core_cm3.h" and use NVIC_DisableIRQ(1), but it gave me 30 ERRORS and messages like "...error: #1114: this feature not supported on target architecture/processor".
How can I simply disable/enable IRQ's for my SAM7X (which C-procedures to use)? I'll appreciate comments to this isse.
