SAMD21 family

Official Hardware Classic Zero
1

Hi guys,

I'd like to use the Zero as a prototyping platform for a device I'm making. But seeing the price of the SAMD21G18 is quite high. I'm wondering if first developing for the Zero and then porting to the smaller SAMD21E15 is a sensible approach? Will the Arduino toolchain still be usable on that MCU?

Cheers!

The SAMD21G costs $2.75 at Digikey which seems to me the bargain of the century. The SAMD21E

is listed at $3.75.

Hi

You can use SAMD21E device any flash size. What you need to do....................

  1. Create sketch on SAMD21G18 device
  2. Make sure the peripheral you use is same as in 32 PIN SAME device (check device data sheet I/O multiplexing section)
  3. Import same sketch on Atmel Studio 7.
  4. Modify linker file -
    change flash size and ram size only according to SAME flash size .
  5. Compile the code.
  6. Done -
