Python Shared Memory

I suspect the answers will be short and negative, but is it possible to access the shared memory of ACC using Python?

I find it a struggle to see the shiftlights at times; real life wheel LEDS are visible even in very strong sunlight, but in ACC they aren't. In AC there was a nice glow effect if, if I remember correctly, post-processing was turned up, but that doesn't seem to be the case with ACC.

What I'd like to do is play a tone or a beep when the shiftlights flash (but given that isn't in shared memory I'd happily accept at a fixed RPM of my choosing).

Worth asking, even if it just puts me out of my misery.

 

I'm pretty sure you can use mmap in Python. Might be worth looking it up. https://docs.python.org/3/library/mmap.html
Make sure you only use READ access or it will fail to open.

I don't remember if I got all the data there but I'm sure you can figure out missing pieces with ACC shared memory documentation

 

simhub + Ensi Ferrum's plugin already does shift beeps. Per car and per gear customizable

 

Thank you all. Much appreciated. I'll try the sim hub plug-in, but I remain tempted to make my own just for the fun/satisfaction/learning I'd get.

 

hey,

was also looking for this and have written a small example script. Hope you can use it.

Thank you for that daCoon, that is exactly what I was looking for. The previous example had me a little confused when trying to process the Static data, but your example has helped me understand it much more. Thanks to all in this thread as well!

 

welcome, think if you need the latest state for acc, you can also use the latest doc to update missing values. Only the order and datatype is important.

 

Anyone have any suggestions on how to get the "car left / car right / three wide" notifications? I've looked through the shared mem documents several times but don't see it. I presume it is available, as they do it in Crew Chief. I'm hoping it isn't from calculating the position in the game world!

 

car left / right are indeed from calculating relative world positions, combining shared memory and UDP data to get world co-ordinates then using player orientation data to rotate the co-ordinate frames of reference etc etc. It's a lot of faff

 

@daCoon great work! Finally having something to work with in python.

Anyone of you have the idea if it's also possible to have alle the data from the broadcast API in python. I'm not even able to establish the UDP connection...

 

I am also looking for a way to retrieve broadcast data in python

I use it for my remote pit strategy app https://github.com/rrennoir/PyAccEngineer

I tried to udp too not sure if it still work though https://github.com/rrennoir/PyAccUdpInterface
