Read absolute hall ticks

[ducktrA]

I need the absolute Hallticks. Thus added an enum for it in Codes ({ 0x07, "hall position steps", NULL, UI_NONE, &contentbuf, sizeof(PROTOCOL_POSN), ... ) in alignment of corresponding function and code in protocol.c/h.

Via API i can now do this.

hoverboard.requestRead(HoverboardAPI::Codes::sensHallPosSteps, PROTOCOL_SOM_NOACK);

Question: Where do i find the result once the request is completed?

Thank you.

hi ducktrA, I've not used the protocol implementation externally from C as you have, but I think it should populate the variable you mention - i.e. contentbuf. You should also be able to add a function in your defn line to be called with the data.... s @p-h-a-i-l will be able to help more :).

There are 2 possibilities: You can register a storage location to this code, so each time data is received the variable gets updated: setParamVariable Or you can register a callback which gets called each time data is received: setParamHandler In this callback you can process or copy the data which is temporary stored in contentbuf.

Of course you can do btoh ;)

Have a look at https://github.com/bipropellant/bipropellant-hoverboard-firmware/blob/master/src/protocolfunctions.c to get an idea what we are doing.
