manual chip select for SPI handle

[yefj]

Hello, I have situation with my EFM32LG where i need to define a manualy operating chipselect select .
I tried to implement it by making GPIO port to act as manual CS,
CS gpio goes low. then i send the data ,then gpio cs goes high.
i tried to implement the idia in the code bellow.
Is the methodology correct?
Thank.

SPIDRV_HandleData_t handleData;
SPIDRV_Handle_t handle = &handleData;
SPIDRV_Init_t initData =  SPIDRV_MASTER_USART0;
initData.csControl=spidrvCsControlApplication; //manual CS
initData.bitOrder=1; //MSB first send bit order

initData.port->ROUTE &= ~((1 << 8)|(1 << 9)|(1 << 10));

SPIDRV_Init(handle, &initData);
GPIO_PinOutClear(LED_PORT_A,2); //chip select low starts transmition
SPIDRV_MTransmitB(handle, B31_B24, 8);
SPIDRV_MTransmitB(handle, B23_B16, 8);
SPIDRV_MTransmitB(handle, B15_B8, 8);
SPIDRV_MTransmitB(handle, B7_B0, 8);
GPIO_PinOutSet(LED_PORT_A,2); // chip select high,end transmition

Hi,

Looks good.

If you did the correct port setup and all functions are blocking.
