Basic WIFI app - IRQ problem

Actually weird thing the first time it checks for IRQ:

// Check the IRQ line

ulSpiIRQState = tSLInformation.ReadWlanInterruptPin();

On multimeter I measure 0V, but in register P2IN5 there is 1.

How could that be possible?

Hi Sergey,

Please also check board.c and spi.c for other references to the IRQ pin, so you can change it to pin 2.5.

Hi Aaron,

I checked again. Only place that also references this pin was in interrupt, but I changed it to P2.5 as well.

Im still hanging in wlan_start():

if

(ulSpiIRQState)

{

// wait till the IRQ line goes low

while(tSLInformation.ReadWlanInterruptPin() != 0)

{

}

}

IRQ line doesnt go low. First I was thinking it was MCU problem, but no IRQ line is actually staying high.

Any other ideas?

Thanks,

Sergey

Sergey,

There are functions that enable/disable interrupts for that pin:

SpiPauseSpi();
SpiResumeSpi();
WlanInterruptEnable();
WlanInterruptDisable();
