Just make Risc-V C3 Dual core or quad core )
Maybe higher clock too - 240Mhz+

Re: ESP32 TFT display library

I was able finally to connect NT35510 to K210 with OV5640 at 640x480 capture resolution
Canaan updated their sdk lately and even upgraded gnu Risc compiler

Here is the result: https://www.youtube.com/watch?v=R278v1Qgay8

Re: ESP32 TFT display library

I would like to try this library with also a different MCU - make the code run on Risc-V however this library has a lot of conditional symbol defines and I am not sure what is predefined by default. I am using K210 mcu which just amazes me with speed and easiness. I am working on project with RBG P4...

Re: ESP32-S3 RGB LCD maximum throughput

I don't see any lcd controller mentioned in the docs. Probably some custom silicone so I guess you must figure things out on your own. I would say all glitches are related to slowness of CPU and/or peripheral lagging performance for such large amount of data. Btw PSram speed is quite slow - for 80mh...

Hi,

I'm currently developing a custom board with an ESP32-S3-WROOM-1-N8R8 driving a 800x480 5" LCD display with a 16 bit RGB interface.

May I ask what kind of LCD display it is?
Is it OTM8009A ?

Re: Is it recommended/practical to use C++ instead of plain C ?

I honestly like C++ for all IoT programming and although I program mostly in C# what annoys me is lack of all needed features like multiple inheritance or inline assembly blocks. C# is good for humongous projects and devices with ton of memory and power. Also VSCode is annoying for its lack of corre...
