RE: Re: more serial ports for rabbit3000

Having used Rabbit since the early days with the BL1200 and the Z180 I
stopped using them in new projects after I had issues getting an RCM4000
design to work reliably. Not exactly Rabbits fault as it was another
companies product line based on the Rabbit. It's complete lack of support
for UCOS was the nail in the coffin. Trying to get a complex graphical
display for a control system working without it was no easy task.

 

I moved to the Netburner to start with as I wanted to stay with C/C++ and I
like their hardware and code, albeit as Steve says, it is rather large.
C/C++ requires discipline as a programmer as there is no bounds checking so
you have to be a reasonably good programmer to get the best from it, in much
the same way as working with Rabbit. Netburner uses UCOS 1 and if you have
used this with Rabbit (and if not, why not?) then you will be right at home
with getting it to work.

 

Recently I have been using 32 processors from GHI Electronics with .NETMF
and C# and I have to say, they are great to work with. Heaps of memory and
no issues with limited data space. Not as close to real time as the likes of
Netburner or even Rabbit can do but getting the likes of Networking up and
running in days instead of weeks is a bonus. The latest 400Mhz module is
small and easy to build custom hardware around and with infield updates (via
download or memory card) it makes life much easier. Native graphics with
touch is an added bonus.

 

I may go back to Rabbit if they make the move to 32 bit and create a proper
compiler for them but my days of the 8 bit machines are numbered other than
legacy support. :)

 

 

Sorry for the non-Rabbit post but I am sure others are in the same situation
and looking for alternatives and I am sure they are looking for pointers
from ex-Rabbit users?

I like the PIC line of microcontrollers, so I bought a PIC32 dev kit
to play with. What a nightmare! I've never had such difficulty getting
it to work, especially Ethernet. After some months of struggling with 
it, I shelved it. The Netburner is a much better and easier platform 
to use if you need 32-bit support. But it's physically much larger. 
If you can stand the extra size, and want 32-bits, I think Netburner 
is a better way to go.
