You have probably seen the teensy 4.0 which recently came out. It has a 600 MHz ARM M7 and uses the Arduino IDE. There are also lots of working libraries for it. I ordered one out of curiosity and although the bootloader is beta I didn’t have problems doing the standard Arduino stuff. I was mostly interested in the DAC and ADC which turned out not to be an improvement for my project than what I already have at hand.
I am thinking about building a Arduino style board with STM32H7 series MCU.
I have NUCLEO h743 and its just too fast and lots and lots of peripherals. I want to reduce the size of the board by using 100pin mcu instead of 144 or more pins
I agree it must be IDE supported to be an Arduino.
Several ST ARM based processors are supported, so a design based on one of the STM32H7.... parts should be reasonably easy to add to the IDE. This would give you a 400MHz clocked ARM with 64 bit floating point and 16 bit ADC.
It's not something I would want to do myself, but I think it could be made to work.
Does Arduino Compatible refer to being compatible with Arduino Style Shields or does it mean it is supported in the Arduino IDE or some variation of such like the TI Energia IDE?
To me, to be compatible would mean it is supported in the Arduino IDE. Otherwise it is just a knock-off.
