Firmware Upgrade and fuse settings
Posted: Fri Feb 06, 2015 5:12 pm
Hi,
today I upgraded the firmware of my DSO 062 to the newest one.
Surprisingly I found the fuse settings when reading with avrdude:
...
avrdude: safemode: lfuse reads as AE
avrdude: safemode: hfuse reads as C1
avrdude: safemode: efuse reads as FF
...
hfuse C1 means the controller is running on internal frequency of 1MHz.
On your firmware support site you note:
Fuse setting: extended byte = 0xFF, high byte = 0xC0, low byte = 0xAE
hfuse C0 means external oscillator, I would have expected a setting for a high frequency crystal as I can find one on the board.
I didn't change the settings and everything still works after the upgrade.
Would it be wise to change the hfuse? Will the software run faster?
Regard
Reinhard
