Generate Interrupt and Interrupt Handler MSVC

Posted by andrewalo on January 13, 2015

Hi Guys, Sorry for my first newbie knowledge of freertos. I'm tryng to generate an interrupt to call an handler function.

On the practical guide i've read this statements:

_asm{} //to generate interrupt

static void _interrupt _ far handlerfunc(void) {} //to define handler func

dossetvect{} //to install the handler func

but i think that they're for another architecture,

is there a guide for make this on MSVC?maybe an example.

Thank you :)

As the simulator is running under Windows, and not actually simulating any hardware, it is not possible to generate real interrupts. However you can generate simulated interrupts. See the following link: http://www.freertos.org/FreeRTOS-Windows-Simulator-Emulator-for-Visual-Studio-and-Eclipse-MingW.html#SimulatedISRs

Yeah!i was written how i resolved, if someone needs help:

vPortGenerateSimulatedInterrupt( portINTERRUPT_YIELD2 );//generate interrupt

static uint32_t handlerfunc(void){}//interrupt handler (NOT UNSIGNED LONG)

vPortSetInterruptHandler( portINTERRUPT_YIELD2, handlerfunc );//install interrupt

and in the portmacro.h, #define portINTERRUPT_YIELD2 (2UL)/or another value/

Thank you :) !!!!
