Interesting alternative for STI chips

Don’t know the price, but looks interesting.


#2

Would an existing F4 NETMF port just work on these? Or would it have to ported all over again, due to different I/O, memory, etc supported?

I would imagine you’d need to port it again.


#3

I am sure it will need its own port.

Ram is too small…


#5

@ Justin - There are more coming


#6

Not surprising…

Moore’s Law keeps marching on…

But engineers still don’t know why bicycles go straight :smiley:

Hello,

I just ported to FM4 chip.

Please check CodePlex NETMF for FM3?

thanks for sharing!

@ Kentaro - That was quick! Great job! :clap:

What’s the lowdown on FM4 vs STM32F4? Advantages/disadvantages?


#11

Hello

I am not familiar with STM32.

Advantages

  • Can operate from 3 V or 5 V power supplies
  • DSTC (Descriptor System data Transfer Controller)
    Descriptor based memory to memory transfer like DMA

Disadvantages

  • No model which has ethernet controller now
  • SPI 20MHz vs 45MHz (STM32F4)

Both have SDRAM interface and fast 12bit AD/DA. These are attractive for me.

Hello

I updated NETMF for FM3/FM4 to fix several issues and added NETMF interop library for Adafruit 16x32 RGB LED Matrix.
