Hello
I'm new and first of all I'm looking to some details important for cost determination
if I have a 800x480 7" lcd can I use 384k of the 512 k internal memory of the i.MX RT 1050 processor as rambuffer (8 bit color)?
Or do I need an external ram memory?
Thanks in advance for answers
Andrea
Hi Andrea,
You can see below definitions in fsl_elcdif.h from RT1050 SDK, it can support kELCDIF_PixelFormatRAW8, so you can use 800*480*8bit RAM buffer to drive LCD.
typedef enum _elcdif_pixel_format
{
kELCDIF_PixelFormatRAW8 = 0, /*!< RAW 8 bit, four data use 32 bits. */
kELCDIF_PixelFormatRGB565 = 1, /*!< RGB565, two pixel use 32 bits. */
kELCDIF_PixelFormatRGB666 = 2, /*!< RGB666 unpacked, one pixel uses 32 bits, high byte unused,
upper 2 bits of other bytes unused. */
kELCDIF_PixelFormatXRGB8888 = 3, /*!< XRGB8888 unpacked, one pixel uses 32 bits, high byte unused. */
kELCDIF_PixelFormatRGB888 = 4, /*!< RGB888 packed, one pixel uses 24 bits. */
} elcdif_pixel_format_t;
