Sound generator possibilities of implementation

[JonasErnst]

Had a closer look to the Hyundai Ioniq VESS, which may be uses the same concept as the Kona. Looks like these offer good opportunities to add an own sound. The sound samples (for driving, reverse bing and annoying beeeep) are stored in a SPI flash, and played by the Yamaha sound chip in different speeds depending on the vehicle speed. Was able to read the flash and listen to it on the PC with Audacity Did not yet patch the original unit, not sure whether I go this risk before the TÜV date ;-/
Unfortunately there are different software versions flying around, and the VESS which I ordered cheap, with version 1.00, does not play in my car at all.

Hey uhi, i tried your script but unfortunetly i never got it to work. PeakCan shows Error Warning Passive. I tried it with SW 1.00 and SW 1.01 modules. The module draws around 82mA from the 12V Power Supply. I am unable to recieve and send any messages to the module due to the can bus error. I tried different can speeds, changing high and low, but nothing seems to fix the can bus error. I cant imagine both modules are broken

500kBaud, and you need a termination resistor between the CAN lines. Current consumption looks okay. You could check with oscilloscope whether the CAN talks.

I was running one of these to my Zero EV motorcycle was a very good unit.....till the bike got stolen ..

I recently purchased a Soundchaser EVESS from a guy in Sweden (evsoundsystem.com) that has speed referenced sounds from a V8 to a spaceship. I will be going for the more sensible spaceship or turbine!

Yeah today on my drive to work it came to my mind that i should meassure the can bus termination, I added the resistor just now and its working fine. I am looking forward to install this unit to my car, thanks for all the documentation. And thank you for your quick reply

Did you also have success with the software version 1.00 VESS? I was not able to convince it to play. But now managed to copy the SW 1.01 from the good unit, and flash it on the old unit. Now it plays

Found myself looking for Hyundai VESS parts and stumbled upon this, the Kona VESS seems to be further hacked
Do I understand this correctly that you can configure this via Rs-232 and there is a command line user interface for the VESS?

Interesting. This is a completely different hardware design.
I can only speak for the ioniq unit. This has the pins for a serial, and some related texts in the bootloader. Rest to be found out.

I don't know if this is modded, but I think it's cool

Hey, I was unable to play the sound with the 1.00 Unit but my plan was the same as yours to try to copy the FW over to the other unit. I did not have time to try it and I am glad you got it to work. I am really looking forward to integrate this soundgenerator into my build, next step would be creating a module for zombieverter but I need to look into this as i did not create custom code for it yet

I ordered today a Kona VESS (25€ with shipping)
I'll post some updates once I have it in hand and have toyed around with it
