Does anyone have any recommendations for microcontrollers with LCD controllers for QVGA (320x240)
I have try on the web site for QVGA LCD to buy no luck in Australia all so
I have a QVGA card as the connection are not the same and need a project microcontroller to display on a LCD Screen
The QVGA Card has a 5+ volt rail
The QVGA pin
1 D0
2 D1
3 D2
4 D3
5 DISPOFF
6 FRM
7 NC
8 CL1
9 CL2
10 VDD
11 VSS
12 VEE
13 VO
14 GND

See this project, its photoframe, and use ATMega8,16,32 8-bit AVR uC :

Of course source code is there.

Are you sure the display module you describe does not have an integrated display controller? The pin count seems low.


You can drive a QVGA with almost any MCU as long as the device has enough I/O for the task, like the project tpetar mentions above.

However, if you want to accomplish the task in a reasonable time frame and still have resources for other tasks, I would strongly recommend an ARM, PIC32 or device with similar resources.


I have successfully used a QVGA with a NXP LPC1768 in a commercial project.


If you need a device with a dedicated display controller for better throughput, the NXP LPC1788 is one such MCU which could meet your requirements:

**broken link removed**

Some other devices from the NXP ARM family with integerated display controllers are:

LPC1850, LPC247X, LPC325X and LPC4300.

Of course there are other devices available from numerous manufactures, the LPC family just happens to be the family I'm most familiar.
