TIVAC129 Raster driver

Hi.

I'm setting up the driver for LCD controller for TIVAC129.

I'm able to fill-up correctly the frmae buffer with the screen produced by WM (widget, dialog).

The issue is that I need to re-enable the LCD controller in order to see the window on my LCD.

May be the DMA trasnfer conflict with frame buffer write of WM?

Can you help me to find a correct set up for LCD controller?

Thanks in advance.

Hello,

Please note that I do not have the information which would be required in order to help you set up the TIVAC129 correctly. I would recommend you to request your display supllier for a proper intialization sequence.

Best regards,
Adrian

Thanks for your replay.

Just a bit more information about the WM.

I know that WM can us multiple buffer in order to avoid flickering between frame changes.

Which is the correct init sequence to activate this feature?

Hello,

I would recommend you to follow the instructions in the chapter "Multiple Buffering" in the emWin user manual. Once Multiple Buffering is set up, you will just have to call the function WM_MULTIBUF_Enable() to activate the automatic use of Multiple Buffers by the Window Manager.

Best regards,
Adrian
