Posted on October 30, 2007 at 04:04Hi all,
I am not having much joy in getting my SPI peripherals to work on an IRQ base. Polling works!!! but I am not finding that it triggers an interrupt when I set the receive interrupt. (BSPI_RcItSrc(BSPIx,BSPI_RC_FNE);)
My Init code is as follows. (Using IAR)
// =============================================================================
void SPI_Init(char SPI_Channel_No, char SPI_Mode)
{
BSPI_TypeDef *BSPIx;
// Configure GPIO0's pins to perform alternate function, SPIx (Push Pull)
switch (SPI_Channel_No)
{
case 0 :
BSPIx = BSPI0;
// P0.0 - MISO P0.1 - MOSI P0.2 - CLK P0.3 - SS
GPIO_Config(GPIO0,0x000F,GPIO_AF_PP);
BSPI_BSPI0Conf(ENABLE); // Enable the BSPI0 interface in PCU_BOOTCR
break;
case 1 :
BSPIx = BSPI1;
// P0.4 - MISO P0.5 - MOSI P0.6 - CLK P0.7 - SS
GPIO_Config(GPIO0,0x00F0,GPIO_AF_PP);
break;
} // switch (SPI_Channel_No)
BSPI_Init(BSPIx); // Initialize BSPI1
BSPI_ClockDividerConfig(BSPIx,8); // Configure Baud rate Frequency :-->APB1/8
BSPI_Enable(BSPIx,ENABLE); // Enable BSPIx
if (SPI_Mode == SPI_MASTER)
{
BSPI_MasterEnable(BSPIx,ENABLE); // Configure BSPI0 as a Master
} // if (SPI_Mode == SPI_MASTER)
else
{
BSPI_MasterEnable(BSPIx,DISABLE); // Configure BSPI0 as a Slave
} // else
BSPI_ClkActiveHigh(BSPIx,ENABLE); // Configure the clock to be active high
BSPI_ClkFEdge(BSPIx,DISABLE); // Enable capturing the first Data sample on the first edge of SCK
BSPI_8bLEn(BSPIx,ENABLE); // Set the word length to 16 bit
BSPI_RcFifoDepth(BSPIx,10); // Configure the depth of receive up to 10 words
BSPI_RcItSrc(BSPIx,BSPI_RC_FNE); // Set RX Interrupt Source
} // void SPI_Init(char SPI_Channel_No, char SPI_Mode)
Any help would be appreciated!!!
