Davega hook-up to Stormcore using Flipsky VX2 (UART)

[LAKESHORE]

Hi Everyone -

I’ve been scanning old posts and I can’t figure this out. I hope someone can help.

I have a Stormcore 100D and with a Flipsky VX2 (UART) and I was trying to hook-up a Davega to it also.

The Flipsky remote is hooked-up to the regular UART Port on the front of the Stormcore and it works great.

However, I tried to hook-up the Davega to the 4-Pin “UART3” Port on the side of the Stormcore and I can’t get the Davega to connect to the ESC.

The 4-Pin “UART3” Port has 5V, GRD, TX3, and RX3 and I connected all of the Davega wires correctly.

However, I can’t get it to work.

Is using the “UART3” Ports even an option?

Does anyone run a Davega with a UART Remote?

Any guidance on this matter will be greatly appreciated.
Cheers!

I think you’re maybe runing into the uart3 and uart2 accidentally share a pin so both are not availabe at the same time. (tho not sure if that’s a 100D problem in addition to the 60D problem)

searching for uart3 on the forums finds stuff.

The uart pins of the mcu are mapped to specific set of pins. So there are like 3 different sets of pins for each of uart drivers and you can select between them for each of the uarts. I accidentally selected two sets of uart 3 pins instead of one from uart 2 and one from uart 3. So you could use the ports alternating but not simultaneously. You can also use the pins for uart output at the side and i2c from the main but nobody really uses i2c except for sensors and such.

If it’s a stormcore 60d, it does nothing (they messed up wiring the original batch)

If it’s a 60d+, it does the same thing as the other uart port. It just allows you to connect another uart device. For example, you can get remote telemetry from one port and plug a data logger like robogotchi or metr into the other.

Quick note, you have to be on FW 5.3 or higher to activate the uart3 port on the 60d+

you could try to upgrade to a megan to run off of can.

Are you getting any power at all on the davega?

Can you multimeter the 5v and gnd pins to double check?

Thank you for the responses. I read the other strings on UART3 and I’m still a bit confused. The ESC is a Stormcore 100D in a Lacroix Lonestar Supersport. The VX2 remote is working great and it is connected to the Lacroix Sentinel via the 8-Pin UART Port (see pictures)

Here are my questions:

1. Is it even possible to hook-up the Davega to the UART3 4-Pin Port on the side of the Stormcore and use the 8-Pin UART for a VX2 remote at the same time?

If it is possible, then:

2. What am I doing wrong?

The Davega is getting power from the 5V UART3 4-Pin Port, and I double checked the RX3, TX3, and Ground wires to make sure they match the diagram on the back of the Davega.

The Davega powers up fine. But I get a message that it is not connected to the ESC.

I just twisted the wires together for now to get the Davega working and I will solder them once it works.

Please see pictures below.

i think the answer is no.

I think you could test for continuity between the tx pins on the two ports, (and/or rx pins). if they are connected then they have the early hardware bug, and only one is usuable at a time.

Thanks for the response.

I was running a PPM Remote (Hoyt Puck), and the Davega worked great using the 8-Pin UART Port.

But it is starting to look like I can’t have a UART Remote and a UART Davega at the same time.

I guess that is the way life goes sometimes.

You can’t always get what you want, but if you try sometimes, you get what you need (so PPM and Davega might be my only answer). LOL!!
