Buttons sequence as operation mode change trigger?

[chienMouille]

Hi,

Would it be possible to implement a more flexible configuration for choosing how the operation mode change is triggered?

For instance, I think it could be great to be able to do a sequence of 3 of the display buttons (like a PIN basically) to activate off road mode, and then a single press on menu button for instance to go back to standard mode.

(BBS02B here)

Not possible, this is only firmware for controller. Display does not send button presses to controller. Only sends selected assist level number, light output state, and walk assist state.

Yes I guess that could be possible to implement. It is quite a bit of work to implement something fully configurable like that and I have previously said I won't do it. I think some people have modded the firmware themselves to have their own custom combination no one can know of.

[chienMouille]

Yes, I get it. Any chance you could point me to where I could implement/mod this?
Also, any ressource on how to compile it then?

Thanks a lot

I guess another way would be to make a custom display, which just sends a light state change for instance after à the custom button combination. would need to implement the other commands too of course.

Do you have a reference of the serial communication protocol you implemented ?

[danielnilsson9]

Current mode switch based on light switch is implemented here:

bbs-fw/src/firmware/app.c

Line 206 in 39c373b

void app_set_lights(bool on)

The other signal from display is just above it: app_set_assist_level()

Build instructions are on wiki:
https://github.com/danielnilsson9/bbs-fw/wiki/Build-from-Source

No reference on the display protocol, it is revered engineered from communication between original firmware and display, implemented here: https://github.com/danielnilsson9/bbs-fw/blob/master/src/firmware/extcom.c

If you were to develop a custom display a different protocol might be preferred, this one is very limited.

thank you so much!
I'll post here somewhere if I end up building a custom display!
