FT813 GRAM size 1MB to be increased soon?

<< < (2/3) > >>

FTDI Community:
Hello,

Yes, assuming the images are in the aforementioned ASTC these would be able to be loaded directly from flash memory and not into GRAM.

The images are first stored on eMMC as .bin files, converted using img_cvt.exe, so I assume they are in ASTC.
So loading saves time, but once loaded into G_RAM, they are inflated, and all we need at the same time does not fit into just 1MB of G_RAM.
We may need several MBs worth of bitmap data to be used on a screen page (it being updated with different images).
With the FT813 this is not possible, right, so we need to wait for the new display to become available?

FTDI Community:
Hello,

The img_cvt.exe cannot produce ASTC files, we have a upcoming asset convertor which will support this.
And yes, in your situation this is not possible with the FT813.

So, the BT815/6 is the solution for that problem?

FTDI Community:
Hello,

Yes, I believe for what you are trying to achieve the BT815/6 would be a solution.
