Interrupt processing with uC-OS II

hi,

see the count_binary example for simple PIO.Also,if u want to do it with MicroC/OS-II,u read the simple_socket_server example throughly,everything is given in it.It is slightly difficult,but u have to do it.

all the best

bye

Also, make sure that you have the correct version of the Nios II kit. The free evaluation version, which you can download from the Altera website, does not contain the MicroC/OS-II component.

Many users have been frustrated by not knowing this was the case, so I thought that I'd bring it up if it were your problem.

hai to all niosforum readres

my question is how to write the interrupt service routine ( example for the pio buttons ) with uc os ii ???????????????

the niosii development kit, has a example for processing interrupts with the niosii api.

but how it works with uc-ocii?????

thanks for advices http://forum.niosforum.com/work2/style_emoticons/<#emo_dir#>/sad.gif

It depends on you hwo you design it.

I wrote a own interrupt function for a CAN device.

I used MicroC/OS-2 Event Flags to communicate between interrupt function and the normal program flow.

Interrupt Registration absolute normal

alt_irq_register(CAN_1_IRQ,

NULL,

local_my_avalon_can_advanced_isr);

ISR:

extern "C" // wegen ISR ...... // i use C++

{

static void local_my_avalon_can_advanced_isr

(

void * context, // Dummies - ignore

alt_u32 id // Dummies - ignore

)

{

..... // do something

OSFlagPost(CAN_local_CAN_Event, // event flag group

proc_os_can_flags, // flags according to the result of do something

OS_FLAG_SET,

&proc_u8_error);

}

Function that waits for CAN Stuff:

void class_can_system::my_avalon_can_handler

(

void

)

{

... /// do some init stuff

for(;;)

{

proc_os_can_flags = OSFlagPend(CAN_local_CAN_Event,

L_CAN_ALL_EVENT,

OS_FLAG_WAIT_SET_ANY + OS_FLAG_CONSUME,

L_WAIT_FOR_EVER,

&proc_u8_error);

switch(proc_u8_error)

{

case OS_NO_ERR:

// do normal flag handling

break;

case OS_ERR_PEND_ISR:

..... and other errors - do some error handling

}

}

}
