For testing I have the Land Rover Gear Lever, which also works wonderfully on the VCU, but VCU does not transmit the drive direction to LDU. Is there a reason for this or do I have to map it.

Yes you need to map it in the DU.

Info is in this thread: viewtopic.php?t=3609

It is on the list of being improved to an automatic configuration.

So, I've been trying for some time to transfer the gears from the zombieverter to the LDU, but I just don't understand the CAN mapping, I have also read the can communication on the wiki several times, but unfortunately I don't understand it, I know that you have to set the whole thing on the LDU, the CANIO to receiver, but I don't know how or what, a small example for better understanding would also help
The accelerator pedal values ​​are transferred from the VCU to the LDU side without changing anything, just not the rest

In version 5.32.R and up direction is no longer mappable but has a fixed mapping.

I know that, but how can I make it work, or is it not yet implemented in the firmware

firmware is being updated to include this.

Turns out at the moment only digital inputs are transmitted. Not the Zombie direction spot value.

I have digital inputs on the LDU, so it wouldn't make sense to connect them to the VCU now until the zombie sends the drive direction values ​​to the LDU?

Yes so you have to wait for the update to the Zombie Verter firmware to allow sending from the Zombie to the LDU with OI board anything but digital inputs (into the Zombie)

Update the testing branch after bench testing with my mini board running stm32_sine.
Updates can be found in the Vehicle Testing Branch. https://github.com/damienmaguire/Stm32- ... le_Testing

As always this is to be run at your own caution, please test that the spot values populate as they should before attempting any driving.

forward (din_forward) and reverse (din_reverse) works and is also displayed on the LDU Web, but if you go to park or neutral, the last drive direction is displayed, but din_forward and din_reverse are set to 0

You need to change the type of dir switch used for the LDU to button.

Please keep in mind most of the OI Params in the LDU will still need to be set propperly.

it was already set to a button, I changed it to a switch, now it is also displayed, but the parking position is displayed as neutral, possibly this position is not implemented in the LDU

No it is not. So it will show neutral.

ok, then it works,
thanks for your efforts
