Which Arduino to use?

Projects General Guidance
1

Hey everyone,

I hope i am posting this in the correct place, because i am new here.

I am beginner in Microcontrollers so after i searched alot i can't know which one is suitable for my project.

I wanna control a DAC MAX5217 I2C with a 16bit Arduino to generate 0 .. 5 V from the DAC. But i don't really know which one should i use. Any advices? on which to use and which software, tools i need?

i read an article about choosing the right microcontroller so basically i have to know which interfaces i need.

My Microcontroller should have the following : atleast 2 I2C, SPI, USB and many digital inputs outputs, PWM, The controller should also be pretty precised. Basically i want the best Microcontroller to control my DAC MAX5217 its a longlife project so the cost is not so important for the Controller.

Thanks alot.

Regards,

Fadi

Two I2C? That is relatively rare.

How much memory and processing speed do you need?

There's 8-bit Arduinos and 32-bit Arduinos.....

You would get better answer if you'd actually tell us what you want to do with it. What's your project?

IIRC, the Teensy ≥3.2 boards have to TWI's.

You really need two I2C busses?

I think the Due has two I2C busses; I think that's the only official board that does. (It is based on 32-bit processor, not 16-bit - there aren't any 16-bit arduino.)

A lot of the STM32 chips do, and some of them can be programmed through the IDE using something like STM32duino (a third-party project to support the STM32 micros in the arduino IDE)
