I would like to develop HMI hardware using STM32F746 with 480x272 Graphical LCd, But i have confusion on selection of Graphical LCD?Am i select Graphical LCD with graphic controller or without graphic controller? STM32F746 inbuilt LCD controller.

the easiest way is BuyDisplay 10' Touch RA8876,

it runs on 2x SPI ports.1 SPI for LCD and 1 SPI for Touch.

and leaves your processor running full speed without using the on board LCD controller

Hello TJ,

                      thanks for reply,but i would like to develop a product for home automation system ,so i need many GLCD,and also i have general question,because lcd without graphic controller is cheap.

The alternative is the 4.3' LCD with touch $23 from china

I paid $35 for an 18' LVDS panel, the drive board I made costs about $15.

For 800x600 resolution - only RGB control!

For example my project

Hello Vitaliy,

                         Yes,i knowi,STM32F7xx able to control RGB,but i would like to know GLCD used by you is with inbuilt GLCD Controller or you use STM32F7xx as GLCD Controller?

I used STM32F769 for control GLCD with RGB interface.

I tried control GLSD 800x480 with  SSD1963 controller.

It is very very slow to fill screen1-2 sec for 800x480.

My project for SSD1963

ER-TFT070-4 800 * 480, one contact 3.3V power supply digital part. RGB 8 * 8 * 8. 18 dollars.

The minimum headache when connecting to the st chip, without additional intermediate interfaces.

A large resolution weakly improves image quality, but very well increases the price. On sale there are RGB displays without a built-in D / A converter and a high-voltage stabilizer - from $ 4. Such cheap displays can be used in the presence of experience in analog circuitry.
