Being generic is the whole point of it.
It was renamed because this is a dialin dedicated to Leahi unit and calling the messages DenaliMessage is misleading.
It was renamed to CanMessage for 2 reason:
1. This is a Leahi only dialin, so there is no need to differentiate between different type of Can Messages as there would be only 1 type
2. Calling it CanMessage will make it more future compatible when the dialin get copied over for a new unit development (unlikely in the foreseeable future but possible), removing the need to rename it again

There is no Leahi or Denali CANChannels.
There are CAN channels and the naming is what that channel is being used for.
The collision occurs in the FW and the FW handles it before sending out a message.
When reading a CAN, there are no collisions, so there are no priorities. So I have no clue what you want here.

I have no idea what you are referring to as the link is not working.
The need to define the type and the name of the data being read is necessary, so if it's not here it will be somewhere else, that we can't escape.
Exporting that to different files won't serve a purpose and will only increase complexity as when debugging you will need to reference a separate file.
For the defs it made sense as they are used multiple places, but what a message contains is a single use place, so storing it separately is meaningless as it won't have any use outside of this single function.

fixed

fix typo

I am happy to see that this old code is improving.
I would recommend using the Conversion module instead of strings and DataTypes, as it handles everything automatically.
Examples can be found in the following file in this CR:

Please add a docstring for the function.
including the intention and parameters with their intentions.

Same for CanChannels.
The Channels we are referring to here are Leahi's or Denali's.
Channels mainly have no meaning beyond their priorities when a collision occurs.

I recommend DenaliMessage or LeahiMessage, as CanMessage is generic, whereas Leahi/Denali indicate that the protocol is also implemented in the message we are sending.
I'm not sure why the name was changed, as it is a lot of change.
Also, there is no CAN Message.
There is a CAN Frame and a Leahi/Denali Message.

change to td_powerOff_wARNING

Could you just leave it as or TBD_B7 = 0xB7 ?
So it will be easy to see that the msg id location is free to use

Update the name.
