Hi Everyone,
I am currently working on a project interfacing Mitsubishi 3.5" 240 x 320 Graphic LCD (datasheet attached) to PSoC 5LP using External RAM.
I have set up everything according the datasheet. Now, I am trying to display an image, but I do not see anything on the display. Please find my project attached with this discussion as well.
If any one has can share any experience with on-chip controller in PSoC, it would be of great help. Thanks in advance.
P.S: I have looked in the forum with regard to projects using on chip controller using PSoC 5 LP and i was not able to find any references.

Hi,
I have no experience with graphic LCD, but a few thoughts:
1) can you connect a logic analyzer?
2) do you use LCD reset signal? If not, try to control reset line as indicated by datasheet
3) the datasheet you provided also mentions driver IC ST7789, did you use the corresponding datasheet as well? Maybe you'll find adaptable example source code on the web
Regards

I see that you have clock set to 12MHz, please increase the clock frequency based on your interface as mentioned below and let me know if it works:
