No soy muy amigo de Proteus, pero andaba probando una cosa en el simulador y me hace algo extraño que no comprendo.
Lo publico por si es uno de los clásicos errores de Proteus, o por el contrario, es que estoy haciendo algo mal.
Lo que estoy probando es los ejemplos de RTOS que vienen en el CCS. Concretamente, el ejemplo
ex_rtos_demo_tasks.c que es primero de los que hay y que pego a continuación:

#include <18F452.h>
#use delay(clock=4000000)
#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7)
// this tells the compiler that the rtos functionality will be needed, that
// timer0 will be used as the timing device, and that the minor cycle for
// all tasks will be 100 miliseconds
#use rtos(timer=0,minor_cycle=100ms)
// each function that is to be an operating system task must have the #task
// preprocessor directive located above it.
// in this case, the task will run every second, its maximum time to run must
// be less than or equal to the minor cycle, and there is no need for a
// queue at this point, so no memory will be reserved.
#task(rate=1000ms,max=100ms)
// the function can be called anything that a standard function can be called
void The_first_rtos_task ( )
{
printf("1
");
}
#task(rate=500ms,max=100ms)
void The_second_rtos_task ( )
{
printf(" 2!
");
}
#task(rate=100ms,max=100ms)
void The_third_rtos_task ( )
{
printf(" 3
");
}
// main is still the entry point for the program
void main ( )
{
// rtos_run begins the loop which will call the task functions above at the
// schedualed time
rtos_run ( );
}
El problema es que cuando simulo paso a paso, al llegar a la única instrucción del main,
rtos_run() el programa se reinicia.
¿Alguien tiene solución?
