davegax-v5-installer v1.2
This will install the firmware version 5.01 on your DAVEGA X.
Before you proceed, it's recommended that you create an online backup:
Menu > Update & Backup > Backup > backup config & data
Make sure you have the CP2102 drivers installed and connect your DAVEGA to the USB port.
You will also need internet connection.

This baud rate is used when DAVEGAX is connected over USB to computer just for update process. This is not the same baud rate as DAVEGAX uses for connecting to VESC.
@Dunkan, could you please check whether it’s any better with the latest firmware (v5.04rc2)? Once you install that one, DAVEGA will only look at the motor 1 data for energy discharged/recharged and will interpolate for the total number of motors. That should give you better consumption/range estimates. If it doesn’t get better you can return to the original behavior by setting Misc > interpolate energy = disabled.
@janpom it’s better! Much more accurate range estimates. The only thing is the refresh rate is pretty slow, I don’t know if it’s my set-up, but i will accelerate and the screen stays stuck on 5kph even though im at like 30, and it takes a good 4-5 seconds to update
Great that the range projection improved. Regarding the refresh rate issue, are you sure that’s actually related to the firmware update? Have you tried if it goes away if you downgrade to the previous version?
That sounds more like a VESC communication issue. DAVEGA is having hard time getting responses from the VESC and thus it takes long to get a screen update. That could be a hardware problem – cable connector coming loose, or cable being pinched somewhere.
nice work as always Jan
