Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : Teensy 4.0 fastest microcontroller, 1MB RAM, MM Basic?

Very powerful and small board.
With 2MB Flash and 1MB Ram would make a very good MM Basic candidate.
Peter M, what do you think?

Anyone interested in trying it with Arduino development.

Ordered a couple at $20 each, reasonably priced.

Hi johnL
this product seems very interesting, but I would make 3 remarks:

1-a 600mhz processor NXP is no better than the stm32h7 at 480mhz (2314 coremark for the nxp and 2400 announced for the ST).

2- I do not know which is the fastest for the displays, a 600mhz processor and a spi bus, or a 480mhz processor and a 16-bit bus.

3- this kind of card with many multiple outputs functions but not many pins (the same pin is used for serial, i2c or spi or audio, etc) has the disadvantage of being too limited in number of IO and so juggling between IO

for that, i think that teensy 4.0 is a good card for arduino's dev Dyi, but not the best for Micromite family

Thanks for the heads up. Interesting that it has a pixel processing pipeline. I wonder what sorts of graphics modes it can generate via VGA or even DVI? I've ordered a couple to test out.

The best thing about Teensy is the audio edit system (see video). Something adapted for the H7 in my opinion would be the best.
