[ts-7000] Re: real time application

["PeterElliot" <>]

Hi Adriano,

Check out the ADC Device Drive in the file section of the group. It 
implements an interrupt driven background task which should be 
modifiable for your application.

The only thing to decide is how to implement the getSpeed() (assuming 
it's not a simple register read) so that the interrupt is does not 
take too long.

Hope this helps,

PJE
