Increased processor speed #63

Increase processor clock speed from 16MHz to 40MHz?

What still needs to be decided?

What still needs to be done?

MatrixPilot_mw4 by Mark Whitehorn is running at multiple speeds. I have tested 
the 40mips option on UDB4. Mark is testing UDB5. It would be good to know 
Mark's high level plan for his branch code ?

Assigned to Mark until he says otherwise.

current branch status is in 
https://code.google.com/p/gentlenav/source/browse/branches/MatrixPilot_mw4/Matri
xPilot/branchStatus.txt

bench tested on UDB4/5 at 16,32 and 40 MIPS, on AUAV3 at 16,32,64 and 70 MIPS

initial plan for branch was just to fix problems with ADC and higher MIPS and 
call it 4.1

But I've also finished porting the HEARBEAT_HZ parameter and serial I/O ring 
buffer from MatrixPilotMulti and added a non-blocking debug print facility for 
MAVlink.  As part of that work, the DCM updates now occur at 200Hz, synchronous 
with MPU6000 interrupts.

I'd suggest that 4.1 should now be a bugfix plus performance improvements 
release.
