SPI problem

Legacy Legacy AirPrime modules

Hi

I am trying to set up spi for an LCD that I am using, the communication is thus only one way.When I subscribe to the SPI and write to it, the result is correct but when I try to measure the clock or anything with an ossiloscope, there is only noise. Is there something i missed? I attached the code to make it more clear. I am using pin 19 as the chip select.

Any help would be much appreciated.

#include "adl_global.h"

const u16 wm_apmCustomStackSize = 1024 * 3;
#define OUTPUT_PIN 19

adl_busAccess_t busAccessMode = { 0x00, 0x00 };
s32 busSubscribeHandle;
s32 MyGpioHandle2;
adl_ioDefs_t PIN_DESCRIP2 = ADL_IO_GPIO | OUTPUT_PIN | ADL_IO_DIR_OUT;

void SPI_Write(u8 *Data, int DataLenghts) {
	s32 adl_busWriteAnswer;
	TRACE((2,"Write"));
	TRACE((2,(ascii *)Data));
	adl_ioWriteSingle(MyGpioHandle2, &PIN_DESCRIP2, TRUE);
	adl_busWriteAnswer = adl_busWrite(busSubscribeHandle, &busAccessMode, 10,
			Data);
	TRACE((2,"Result %d",adl_busWriteAnswer));
	//adl_ioWriteSingle(MyGpioHandle2, &PIN_DESCRIP2, FALSE);
}

void MyTimerHandler(u8 Id, void * Context) {
	u8 *buffer;
	buffer = (u8 *) adl_memGet(10);
	wm_memset(buffer, 0xFF, 8);
	buffer[8] = 0x00;
	buffer[9] = 0x00;
	SPI_Write(buffer, 10);
	adl_memRelease(buffer);
}
