[Ovmsdev] Introduction to OVMS DMQ

[david muñoz quiroz]

Hey Michael,

Thanks for the information I really thank you to all of you, I know as developers we are always busy, I appreciate the info, I will try to get the HW sooner than later and start my journey, I am Mexican but I live in MI USA, I have a personal old car project that I would like to make smarter (A Toyota Highlander 2008) so I would like to be able to monitor all the information and probably later integrate a media system with use of Raspberry Pi but I am going step by step, thanks everyone for the help and support,

Have a nice rest of your day,

Best regards,

David M.

David,

the OVMS is widely used by normal end users, these all buy the standard hardware, and so do most of us.

Mark Webb-Johnson, the creator of the original design, takes care of producing OVMS modules in Hong Kong. These can be bought from the distributors linked here:
https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3?tab=readme-ov-file#links

There's now also, thanks to the work of Christian Zeitnitz, an alternative for developers in using the Lilygo T-Call series:
https://github.com/zbchristian/OVMS-Lilygo-based-Module

The Lilygo based modules are less capable and don't have an FCC/CE approval, but include everything necessary to actually be used in a vehicle.

To just run the software, mostly any ESP32 WROVER development board will do. You'll need to reconfigure the build to exclude all OVMS hardware extensions, and of course you won't be able to just connect the board to a car, as the transceivers are missing, but you can take first steps in learning how the system works. You can simulate receiving CAN frames through the "can … rx" command.

Regards,
Michael

Hi Michael,

Thanks for the welcome, I have actually done my reading homework already and I can say that is was very well conducted, as long as an engineer reads them we are safe haha, I will take an advantage and ask how can I get a device to put hands on it and start doing flashing and using it to get confident on it,

Can you help me about how everyone else has been building his own devices or who can help me in this start-up process?

Best regards,

David M.

Welcome, David :-)

Don't hesitate to ask when you encounter questions, documentation is -- as usual ;-) -- far from optimal, even for central framework concepts. But the code is pretty clear and readable.

Contributions are of course welcome on all levels.

Kind regards,
Michael

Hi everyone,

My name is David Muñoz Quiroz, I would like to be part of this incredible group and help with the creation of OVMS project(s), I am currently Senior Software Architect in Joyson Safety Systems (Automotive industry), it has become to my attention be part of something bigger than my current organization and I was starting to create my own module to learn and have fun with my vehicles when I realized about this incredible open source project, I feel myself identified with this group and I hope I can be accepted and I can contribute with some of my knowledge and absolutely learn from each other,

Best regards,

David Munoz
