I'm getting some problems with my code, some context:
Currently i'm using a ePWM (50khz) to trigger the ADC, and the End Of Conversion trigger the CLA task.
In my code, i have a Finite State Machine (with 6 states), and, in the state 2 i need to run only the task 2, and in the state 3, i need to run only the task 7. in the other states, i don't need the CLA.
The FMS seems like that:
case sync_pll:
sw1 = 0;
sw2 = 0;
if (DmaClaSrcSelRegs.CLA1TASKSRCSEL1.bit.TASK2 == 0)
{
EALLOW;
DmaClaSrcSelRegs.CLA1TASKSRCSEL1.bit.TASK2 = 1;
DmaClaSrcSelRegs.CLA1TASKSRCSEL2.bit.TASK7 = 0;
EDIS;
}
if ((vg_q1 > -1)&(vg_q1 <1))
{
estado = pre_charge;
vg_q1 = 10;
}
break;
case pre_charge:
sw1 = 1;
sw2 = 0;
if (fault == 1)
{
estado = fault_mode;
}
if ((vdc > 528)&(fault == 0))
{
estado = normal_mode;
}
break;
case normal_mode:
sw1 = 1;
sw2 = 1;
if (DmaClaSrcSelRegs.CLA1TASKSRCSEL2.bit.TASK7 == 0)
{
EALLOW;
DmaClaSrcSelRegs.CLA1TASKSRCSEL1.bit.TASK2 = 0;
DmaClaSrcSelRegs.CLA1TASKSRCSEL2.bit.TASK7 = 1;
EDIS;
}
if (fault == 1)
{
estado = fault_mode;
}
if ((boton_2 == 1)&(fault == 0))
{
estado = apagado;
boton_2 = 0;
}
break;
If i debug the code state by state from the beggening, it works, but my problem start when i turn off all the task (because in the other states i don't need that operations), so, when the state turn on the task again, it doesn't response. I don't know what is the problem, is something like if the CLA doesn't recognize the ADC_EOC trigger, so, never get into the task, i don´t know if i can change the task source over the execution of the code.
Any idea about what is happening??
i don't know if this is the worth way to do the FSM with a separately CLA task, turning on and off each task.
Any idea will be helpful
Thanks!!
