Transferring the frame buffer contents to external display controller via SPI

Hi,

I would be using a external display controller to drive an 7" TFT display. The framebuffer contents will be transferred to the external display controller via 4 wire SPI interface (LPSPI3). I am using FreeRTOS. I would like to know how to use the driver 'fsl_lpspi_freertos.c' to transfer the frame buffer contents. Is there any example code to show the usage. Your help on this is highly appreciated.

Thanks.
