Firmware v4.09

Most important updates:

  • faster start up
  • LLT Power BMS support (experimental)

CHANGELOG entry:

- caching CAN IDs (faster startup)
- LLT Power BMS support (experimental)
- configurable update interval
- ignore decrease in charged/discharged energy (workaround for a VESC bug)
- fix: updating config from Metr CAN fails when imperial units are used
- fix: time retrieved from Metr CAN does not have correct time zone

This is probably the last v4.x release. v5.01 is ready and all new developments will go into v5.x. The idea is that v5.x will initially have:

  • v5.00 - equivalent to v4.01 + new partitioning
  • v5.01 - equivalent to v4.09 + new partitioning

The v4.01 is the last firmware version that works with the Unity legacy firmware. I’ll provide the v5.00 equivalent so that customers who receive a new unit with v5.01 pre-installed will have a chance to downgrade to a version that works with the Unity legacy. Downgrading from v5.x back to v4.x over the air won’t be possible.

I’ll get started on the v5 installer. Since it’s fairly simple (very similar to v4 installer), it should be available later on today or tomorrow.

Mac OS version of the v5 installer is available for download here. Windows version coming soon.

Guinea pigs with a Mac needed. :sweat_smile: @rpasichnyk? :pray: :pleading_face:

This looks awesome dude! I imagine it would be super handy!

I love practical tool design. Sometimes i’ll spend more time making a jig/tool/mould to get a job done than it would take just to do the job, but I can’t help myself :sweat_smile:

It runs, but have no time at the moment to do actual upgrade

Guinea pigs Senior DAVEGA testers with Windows needed! :slight_smile:

Disclaimer: If you have a custom splashscreen, the davegax-v5-installer v1.0 won’t preserve it. I only realized it now. I’ll fix that and release as davegax-v5-installer v1.1.

Edit: Done.

Sup - I made a video on the DaVega!

There will be a follow up to this, going through all of the software setup and outlining the user experience

If anyone has questions about capabilities, or anything they want to know before buying, put your questions here and I’ll answer them in that second part.

Has anyone tried updating to v5 yet? Any success stories to share? :slight_smile:

I’m anxiously waiting for my davega to be delivered today :slight_smile: I’m going to use it on my spintend ubox powered dual motor scooter. Will I be able to keep my custom bluetooth module connected ? The other side of the VESC is all taken up with the throttle/brake connections.

I believe there are two UART ports on the ubox. If you have both occupied I’m afraid you’ll either need to sacrifice the BT module or use a PPM remote to free up the other UART port.

his throttle and brake are presumably using ADC since they’re for a scooter, which is on the same JST. He should be able to use a DaveGa from the tx/rx (which shouldn’t be in use) and 5v/gnd from one of the other headers (assuming you’ve swapped all davegas to 5v)

That’s what I was planning to do. And yes… I do use ADC1 and ADC2 for throttle/brake respectively. I use the other UART port exclusively for the BT module.

Just thought of something… does davega pull stats from both VESCs ? The one I will directly connect to and the one on the CAN bus ?

In case you need a 2nd UART, I would recommend the usplit. I have davega running through 1 usplit connection and a line to my arduino which I use to control my board lights running though the 2nd usplit connection. My usplit is connected to 1 side of my ubox and the other side is occupied by the built in remote receiver.

Yes, it pulls data from all VESCs on the CAN bus.

I just powered it on and it seems to work great :slight_smile: Tell me… is there a way to edit fonts, colors, etc to our liking more ? I know my way around microcontrollers and their file systems very well. I’ve programmed a lot of projects in the arduino IDE and played with ESP1866 and ESP32s…

Unfortunately not. The code is closed source.

It would be nice if you considered and update that would allow a little bit of customization. Maybe editing an external config file or a couple of customization items in the gui. Also, it would be nice if it were able to connect and get information from a Daly BMS. I can help with that if you’d like.

I like the gui how it is. :smiley:

That’s probably doable with the bluetooth module. I have an experimental implementation of a BT communication with the LLT Power BMS.

Is there a documentation for the Daly BMS communication protocol?
