Hello,

I try to use a TFT-panel with a lpc1788. I use as reference the source code for MOD-LCD.4.3"+ evaluation board. My config are good, I see my DOTCLK at the good speed but I can't see anything on the pin 2.4 (LCD_Enable_m). The mux register is set to FUNC_7, TFT and other parameters are ok but nothing appears on my screen except ugly bar of any color. I set a buffer of y lines and x pixels that I used as UpperPanel Frame base (single mode) but nothing ...
Anybody can help me to do a check of what I have done or give me tips please ?

HI all,

I solved my problem, that was due to the buffer (I use now 0x20000000). So now, I am able to use the mod-LCD.4.3"+ board with a code based on FreeRTOS/lpcOpen library (draw/cursor) and external SDRAM (buffer is now Dynamic memory chip select X address).

Thanks
