Has anyone else experienced a completely white screen on an MD4 after start-up but application file seems to work properly? The problem is very intermittent, it happened approximately three times during a week of testing a prototype (perhaps 100 boot up cycles).
Cycled ignition key off and back on to rectify.

If you use the Asus WL-330NUL Router for wireless connection, is it acceptable to power this from Vref+ or do we have to provide a separate 5v power supply?

application cycle time

Why MD4 have a bigger application cycle time (min 25ms) compared to MD3 (min 10ms), even MD4 have more powerful processor than MD3 have?
We need as small cycle time as possible (10ms is maximum, 1 - 5ms would be ideal)
Our speed sensors give 1000 pulses (top speed) in one second (1 pulses in 1 ms). When software cycle time is too big the reaction time for the sensor signals is too slow and we don't get our system accurate enough.
That is the biggest problem with IQAN, the reaction time is too slow.
Is there any way to change MD4 / MD3 cycle time smaller?
