Hi there @Peemouse

Have been searching for some code that has this function implemented so I can use it in the arduino, but so far without success. I don't know what are the transformations required in the messages to actually send such command, using the libraries that are currently created.

The idea here was to sent commands to a slave vesc, for instance, setting RPM's. I've tested the CAN master-slave communication through VESC tool and is working well. It is just the code adaptation in c++ that I have no idea how to perform. I don't even know how is supposed to work with such function, while sending a command.

I would appreciate the help of anyone who reads this. Have a nice day!

Hello,

I'have try to use the setLocalProfile method from your library.
But in my case, it is not working. When I send the data, the VESC reboots or it becomes bricked.

I may be wrong, but it seems to me that the issues are coming from the method used to send float32 over the UART port.
In your library, you're using the buffer_append_float32 method whereas the Vesc firmware is waiting for floats formatted with buffer_append_float32_auto

Does the method was working on your side?

( I'm working on 4.2 Vesc from Flipsky with the 5.1 FW and an Arduino Micro. )

Thanks !

Sorry for the delay @Peemouse I just had left work. I am opening here the issue as you previsouly asked me. Regarding the getVescValues Arduino sketch, i am getting these weird values as seen below.

For context, these values were read for both your previous and updated versions. I used both baudrates at 115200 and added the line UART.setDebugPort(&Serial); after UART.setSerialPort(&Serial1); . Did not touch in the c++ files. Tomorrow, once I am back at work i will proceed with any suggestion that you may find relevant. Again, thank you so much for your help.

Hi, we are sorry to bother You, we are students from Germany and we have some troubles with your code.
we get the following Output running the getVescValues example:

We added UART.setDebugPort(&Serial); to your code. The VESC is set in PPM&UART mode.

We also tried using a voltage divider but it didn´t change the result.

Do You have any idea, that could solve our probleme. We would appreciate your help.

Hello, im trying to pull a single value (data.inpVoltage) using your COMM_GET_VALUES_SETUP_SELECTIVE that you have implemented but given the basic coding skills im not sure how to go on about it.
i see that i have to calculate the mask which i get 88 in the mask(hex) field.
Do i need to also update struct dataPackage to contain just float inpVoltage; or i leave it as it is?
