Dear all,
I'm new to omap l138 ARM processor, Now i have to work on SPI I red the datasheet related to this and initializing the SPI,
I'm using hawkboard. i made the SPI_init() written below
*SPIGCR0 = (unsigned int) (*SPIGCR0 & (0x00000000 ));
delay();
*SPIGCR0 = (unsigned int) (*SPIGCR0 & (0x00000001 )); // resetting the SPI
*SPIGCR1 = (unsigned int) (*SPIGCR1 & (0x0 << 24 ));
*SPIGCR1 = (unsigned int) (*SPIGCR1 & (0x0000 ));
*SPIGCR1 = (unsigned int) (*SPIGCR1 & (0x3)); //Configure the SPI for master by configuring the CLKMOD and MASTER
*SPIPC0 = (unsigned int) (*SPIPC0 & (0xFFFFFE01 )); //Configure the SPI for 4-pin with chip select
*SPIDAT1 = (unsigned int) (*SPIDAT1 & (0x00 << 24 )); // selecting the SPIFMT0 from DFSEL bit
*SPIFMT0 = (unsigned int) (*SPIFMT0 & (0x30001F08)); //Configure the SPI data rate, character length, shift direction, phase, polarity and other format options
*SPIDELAY = (unsigned int) (*SPIDELAY & (0x06030000 )); // CS delays like C2TDELAY and T2CDELAY
//*SPIINT0 = (unsigned int) (*SPIINT0 & (0x01000003 ));
*SPIGCR1 = (unsigned int) (*SPIGCR1 & (0x1 << 24 )); // enabling the SPI engine
i followed the manual
And in my main program calling thr tx_spi() in while loop
the tx_spi is written below
void Tx_spi(void)
{
*SPIDAT0 = (unsigned int) (*SPIDAT0 & (0xAA));
}
By all doing this i'm not getting the clock on CKl pin
is there any setups are remaining?
