spi pdc aic interupt

i need some help with using aic with pdc. How do you initiate it. This
is how i set it up.

// Configure interupt when End of Transfer
AT91F_SPI_EnableIt(pSPI, AT91C_SPI_ENDTX);

// Configure the AIC for SPI interrupts
AT91F_AIC_ConfigureIt(AT91C_BASE_AIC, AT91C_ID_SPI0,
AT91C_AIC_PRIOR_HIGHEST, AT91C_AIC_SRCTYPE_INT_HIGH_LEVEL, SPI0_Handler);

// Enable the interrupt on the interrupt controller
AT91F_AIC_EnableIt(AT91C_BASE_AIC, AT91C_ID_SPI0); Start a New Thread

Hi,

Did you set the peripheral clock (PMC_PCER) ?

Eric.

Do you mean this

AT91F_PMC_EnablePeriphClock(
AT91C_BASE_PMC, // PIO controller base address
((unsigned int) 1 << AT91C_ID_SPI0));

// from lib_AT91SAM7X256.h

}

Yes.
You have to set the internal MCK clock for each peripheral, disconnected by default for lower consumption.

And, of course, you have to set others parmeters like number of bits, transfer rate, ... depending of your application.

ok the clock was already enabled. Do i have to enable it for the aic too?
If so how do i do that?

is there some special trick to get the interrupt working with spi. My
code doesnt cause a interupt. Am i doing something wrong??

AT91F_PMC_EnablePeriphClock(
AT91C_BASE_PMC, // PIO controller base address
((unsigned int) 1 << AT91C_ID_SPI0));

// Open PIO for SPI0
//AT91F_SPI0_CfgPIO();
AT91F_PIO_CfgPeriph(
AT91C_BASE_PIOA, // PIO controller base address
((unsigned int) AT91C_PA15_SPI0_NPCS3) |
((unsigned int) AT91C_PA16_SPI0_MISO) |
((unsigned int) AT91C_PA17_SPI0_MOSI) |
((unsigned int) AT91C_PA18_SPI0_SPCK), // Peripheral A
0); // Peripheral B

/*2. Configure interrupt for SPI0 in AIC*/
//AT91F_AIC_DisableIt(AT91C_BASE_AIC, AT91C_ID_SPI0);
// Configure the AIC for SPI interrupts
AT91F_AIC_ConfigureIt(
AT91C_BASE_AIC,
AT91C_ID_SPI0,
AT91C_AIC_PRIOR_HIGHEST,
AT91C_AIC_SRCTYPE_HIGH_LEVEL,
AT91F_SPI0_Interrupt_handler);
// Enable the interrupt on the interrupt controller
AT91F_AIC_EnableIt(AT91C_BASE_AIC, AT91C_ID_SPI0);

/*3. Configuration SPI*/
// Reset SPI
//AT91F_SPI_Reset(AT91C_BASE_SPI0);

// Configure SPI in Master Mode with with cs
AT91F_SPI_CfgMode(AT91C_BASE_SPI0, SPI_MODE);

// Configure CSx
AT91F_SPI_CfgCs(AT91C_BASE_SPI0, 3, SPI_NPCS3_CONFIG); //CS3

// Configure interupt when End of Transfer
AT91F_SPI_EnableIt(AT91C_BASE_SPI0, AT91C_SPI_TDRE);

// SPI_Enable
AT91F_SPI_Enable(AT91C_BASE_SPI0);

do i have it init it in start file to work??

something like this?? the startup file i have do have this...

/* Initialize AIC
****************/
AT91C_BASE_AIC->AIC_IDCR = 0xFFFFFFFF;
AT91C_BASE_AIC->AIC_SVR[0] = (unsigned int) defaultFiqHandler;
for (i = 1; i < 31; i++) {

AT91C_BASE_AIC->AIC_SVR[i] = (unsigned int) defaultIrqHandler;
}
AT91C_BASE_AIC->AIC_SPU = (unsigned int) defaultSpuriousHandler;

// Unstack nested interrupts
for (i = 0; i < 8 ; i++) {

AT91C_BASE_AIC->AIC_EOICR = 0;
}
