Selecting a MCU
Posted: Wed Oct 09, 2013 5:45 pm
So my question is one that most viewing have and afraid once they see its complexity. Selecting a MCU based off several posts is rather difficult as the firmware would require some hacking to make work? Though it makes no difference to me, I would like to help sort the confusion and find a cheaper more versatile route then a MS1 kit. I spent 6 hours looking a up most of this info lol
The FreeEMS firmware was developed for the MC9S12XDP512 Microcontroller on the AD9S12XDP512M2 unit, but many user have found other units with a different controller all together and thought one would work in place of another. The MC9S12XDP512 is apart of the S12X family and often confused with the S12. The 512 is the k-bytes of Flash and my understanding the FreeEMS firmware requires about 350kb of flash space.(correct me) The extra space could be used at a latter date or used as a buffer.
Could use some help to make a list of usable MCU's and we can look for good distributors. With working links...

AD9S12XDP512M2 -http://www.technologicalarts.ca/shop/st ... ation.html
They are also pre flashed with Freescale Serial Monitor
Funky
MC9S12XDP512 -http://www.wayengineer.com/index.php?ma ... cts_id=281 Needs to be flashed to be usable
Support/firmware- viewtopic.php?f=9&t=2141 - viewtopic.php?f=62&t=1515&start=70
Unsure
elmicro CardS12.XDP5 - http://elmicro.com/en/cards12.html would be a blank and need a flash
AD9S12XEP100M2 - http://www.technologicalarts.ca/shop/st ... ation.html
Faster all around and should be more accurate. Is the Non-multiplexed 8MB expanded memory bus used with FreeEMS? other then that could be a sweet upgrade for most.
