    Hi,
    i'm building a AVR Atmega 16 hardware driver for gauges and motors and i have i question. Where can i find any information about Interface Output data format?

    I'm asking about what should I enter. I know about rs232 transmision, and i have programmed MCU to format 5 x 1 (0b00000001).
    Now MCU is at simulator mode, now he is waiting to data frame {(1), (kph + 2)/2, gear + 2 (r is 3 etc), axis horizontal, axis vertical, 2(end of frame), and mcu is waiting now for next data, until the pc sent the 5x2 frame (simulator stop).
    At game engine should i type it binary,hex, or dec, and what should i type to sent axis info.

    Thanks,
    Pixello

    Ok with SimTools our Axis data is controlled and outputted by the Game Engine and for dashboard control and stuff along those lines are only controlled via the Game Dash , So to run the set of data you want you will need two separate interfaces presently.
    Or maybe another method to combine the two outputs to one output is to send the data from both via a NET interface and build a custom windows app to read the two NET ports and combine this to the serial code that you need to spend to your interface.

    I found info, that if i want to have output i have to write at example <1><Axis1><Axis2><2> at interface output at game engine intefrace tab. But can i send <(Axis1)+2>? I have my MCU connected to this same pc, but i want to get every axis info at 1 frame (8bit, char format) and i preffer to have 5 first numbers restricted to control the hardware, so i need to have Axis data always bigger than 4. If i wont get another option i just make a "hard" data packet at mcu. After i finish i'll send here pcb and code for mcu.

    Thanks for reply,
    Sorry for mistakes,
