[lpc2000] Sensor data "streaming" in real time

2006-01-19 by Marko Pavlin (home)

Hello!

I solved "heap problems" with stdlib's malloc(); So far it's fairly OK...

Now I need some help with real time sensor signal transport over some 
PHY layer (either wireless or wired). Importance is efficiency (smallest 
protocol overhead with maximum payload) and "real-time-ness". That means 
if I sample x(t1), x(t2)... x(tn), I would like to reproduce x(t1+T), 
x(t2+T)... x(tn+T), where T is shortest possible delay. Sampling is 
1ks/s at N channels with 16 bits, where N is 1...8.

Are there some standard protocols or implementations for "streaming 
sensor signals"? I looked for  Real Time Streaming Protocol but it's 
really heavy weight category for sensor applications.

MCU is LPC213x.

Thans!
