Decision on plantform. |
|
|
We want to make a portable device for reading some text. It is
made for ourselves, and as a practice of course. So we want get a low
cost on hardware. Some one suggest that MSP430 should work fine, but i
don't know whether it can afford the loads. It seems that lacking of
support free os for MSP430 is another problem. Is there any better
choice?Any help would be appreciated. |

What do you need an OS for ?

To be able to read text from ? so any microcontroller + lcd should do.
Or the device is going to be able to read text ?
Philips lpc2xxx arm 7 chips
<http://www.semiconductors.philips.com/products/microcontrollers/32bit/index.html>
Cheap boards here
http://www.lpctools.com/
More boards
http://www.lpctools.com/
http://bbs.circuitcellar.com/phpBB2/viewforum.php?f=25
Lots of other arm 7 based chips out there. Oki , Samsung, Analog , Atmel to
name a very few.
You can buy clone palm devices (based on dragon ball) for as little as US$10
in quantity.
Could also use an fpga. See fpga4fun.com
New spartan3e fpga starter kits are supposed to be available sometime
in the next few weeks from xilinx. These have an lcd , + ethernet + usb +
vga output +
uart +io etc

I don't understand. If you are making a single unit, then unit cost
shouldn't be a significant concern. If it is for practice, you might
want to choose a target which is appropriate to what you are practicing for.

What do you mean by afford the loads?
It seems that lacking of support free os for MSP430 is another problem.
Operating systems aren't needed for most simple jobs. There may be some
inexpensive RTOSs for MSP430 -- I don't know.
Is there any better choice?
There could be, but without your criteria, it is impossible to know.

Thank you, good site.
it means that would the MSP430 work correct or overworked?
