Titles says it all...

I wondered if there is a reason why M0+ chips do not come in larger flash sizes and offer bigger SRAM. I think these chips have great potentials with such wide peripheral use. It would be great if they had greater than 256KB flash like 512KB flash and 64-128KB SRAM...

By the time you have included the floating point library for printf function + FAT32 file system + 32KB bootloader section and what not...the space gets gobbled up pretty quick.

Why SAMD21?  SAM4 pricing for 512kB+ seems to start at just about where samd21 leaves off (and has a significantly more powerful CPU.)

As westfw says, why SAMD?!

The whole point of Cortex-M0 is that is it for small applications

 

If you need floating point, why not choose a chip with floating point?!

 

But I'm sure Atmel/Microchip are watching the market, and will be in there if they see a real demand ...

 

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

So now there is SAMD5/E5 series! My wish has been answered! Yay...almost pin to pin compatible and perfect IOT chip. Couldnt be any better.
