Hi. I designed many small embedded devices 7 yers ago. I was use Atmel AVR, Freescale S08 and few other chip. But now I return to this work and see ARM 32 bit in all segments. What you think about it? Thank You usps tracking showbox speed test
EFM8 have some cool features,
but as EFM32 does not cost much more, not having to deal with bank switching as you have 1Meg address range with ARM,
not having multiple instructions needed to add two 32bit values together, though C complier will hide it behind the curtains on 8bit machines, it's still there.
if you're a assembler programmer 8051 is easier, I don't recommend asm for ARM so learning C is a must.
Thanks for your question.
Limetech's post above makes some great points about what might feel more comfortable to you.
As well, the blogs that luweiguo posted are great resources for comparing the technical differences between the EFM8 and EFM32 and will help you get an idea on what products will be better suited for your project needs. If you have any more questions on specific features let me know and I'd be happy to discuss them with you.
