MSP430 to connect with LCD/TFT Display with 1600x1200 (UXGA) Resolution

Other Parts Discussed in Thread: MSP430F5529

Hello Folks,

For a digital picture frame i would like to use the MSP430 to connect a 20" TFT LCD display (Resolution 1600 X 1200) via SPI. Do you think this is doable? Is there a LCD controller that can support such a high resolution with SPI? In my research so far i have found some projects for small displays such as this:

2.8" display:

Thanks for your help!

Best Regards.

    You will need 1200*1600*3 = 5.8 MB for a frame buffer. You will need an MS430 with a lot of RAM. (Or an external RAM).

    Hi Illona,
    as Keith indicated, there are two aspects related to your project. One is the required memory, which is not available on any MSP430, and the other point is the update rate, which you're trying to achieve.
    Keep in mind with the given values e.g. 1 frame per second would require an data rate of approximately 5.8MB/s. So the whole thing will be pretty slow. If it's just for more or less static display scenarios, with an external memory, it would be of course possible. If going with MSP430, I would select one with high MCLK capabilities, two HW SPIs and DMA on chip. This means a device from the F5xx family would make most sense. E.g. MSP430F5529.

    Best regards

    Hello Peter,

    Thanks for the recommendation. This is meant for showing pictures so speed is not important. My first approach is to change the frame maybe every 20sec to 30 sec.
    I will have a look at the F5xx familiy then..

    Best Regards.
