Re: [Help-gsl] GSL in a microcontroller

[Miguel Gallo, Jorge]

Hi,

Many thanks for your answer. It doesn't matter the time and relatively money it 
can take up. However it does matter to me the space and power consumption.

I know for instance microcontrollers of Kinetis based on ARM CortexM4 with 
floating point unit (K10 and K20 family). However my concern is how to 
implement a Linux in it.

Are there any soft Linux versions specially for microcontrollers? If yes, how 
are they implemented?

Thanks for your support,
Jorge

Hi Jorge,

Writing code for a microcontroller is very different from writing code
for a personal computer; finding a microcontroller with a floating
point unit is going to be a struggle, maybe your problem is better
suited to a DSP?

I'd have a look through one of the many tutorials on programming
microcontrollers before going too far.  You need to know quite a bit
about the performance characteristics of your code, both space and
time, before investing too much.  Also power requirements and
production volume should come into it; microcontrollers are efficient,
but bigger batteries may be cheaper in the long run rather than
investing a lot of time in developing something that you're only
making a few of.

Then again, if you're doing it for fun, it's a good challenge and will
teach you a lot!
