Flowcode Support Board

Hi!

First, Flowcode Ili9341 component working excellent but:

I have made a test on the Ili9341 display with diferent communication mode. I use a Stm32F0308. The fastes device I can find. I see other who use Arduino IDE is much faster.

Seriel Ok fast.
Spi, very slow
Parallel, approx. same speed as seriel.

I though, that Spi and parallel is the fastest. Is the above ok, I mean is it the Seial always will be the fastest?
Equal in simulation but not in real world.

Thank´s in advance

Hi Jorgen,

They should go like this in order of slowest to fastest.

Software SPI
Serial
Hardware SPI - With a low prescaler
Parallel

For the parallel mode did you have Use Ports ticked and have a complete port loaded? If you can't use a complete port for the data then yes this will have a similar speed to Serial as you loose the speed advantage.

Hi Ben!

Thank you.

Yes for parallel I have rolled all pin out.
