Help me pick a mcu

Post by jomiq »

Hello, I am building a drawing robot/pen plotter machine. Currently I’m using a stm32 mucleo board with a f746gz processor but I’m looking to use a different processor because it has things that I don’t need, like etherne, and lacks things that would be nice, like reasonable example programs to look at... or mooooaaar memoriez.

After looking at adafruits offerings I feel a bit overwhelmed, maybe you can suggest a suitable dev board / thingy if I just list some requirements?

* Accessible documentation and Linux tools
* Good support for Zephyr or FreeRTOS
* On-chip can controller
* Floating point unit
* A oled screen interface would be nice.
* Not too slow, ~100 MHz is fine

My main priority is to find something that is pleasant to work with because don’t we all like pleasant things?

Cheers

The SAMD51 in our M4 boards knows how to use CAN, and we have this one with a built-in CAN transceiver:

Both Zephyr and FreeRTOS work with the SAMD51, and they specifically mention some of our boards. The SAMD51 has 512k of program memory and a 120MHz clock.
