Advice / suggestions on converting numbers to these back-to-front tuples

[jc508]

Hi I am porting code from Arduino to micropython but I have numbers not little endian byte arrays.
Could you please advise how to do this (easily) - better yet could you maybe add a new method say 'set_offsets_numeric'

What I have to convert is ...

*>>>>>>>>>
    Accelerometer: -23 -12 -36 
    Gyro: -9 -2 1 
    Mag: -826 1222 1759 
    Accel Radius: 1000
    Mag Radius: 807
*/
    adafruit_bno055_offsets_t calibrationData;  // declare the buffer, holds 11 variables
    calibrationData.accel_offset_x = -23;
    calibrationData.accel_offset_y = -12;
    calibrationData.accel_offset_z = -36;
    calibrationData.mag_offset_x   = -826;  
    calibrationData.mag_offset_y   = 1222; 
    calibrationData.mag_offset_z   = 1759; 
    calibrationData.gyro_offset_x  = -9;
    calibrationData.gyro_offset_y  = -2; 
    calibrationData.gyro_offset_z  = 1;
    calibrationData.accel_radius   = 1000; 
    calibrationData.mag_radius     = 807;

    myIMU.setSensorOffsets(calibrationData);

Maybe even better again if you give me a few hints how to handle Byte and Bytearray I could write the module and give it back to you. I am going to have to write it anyway.
Thanks
JC

I'm sorry but I don't follow your query. The example you give above only deals in numbers, and the driver produces (tuples of) numbers. Where do the bytes and bytearray objects arise?

Perhaps you could give an example of the exact type of conversion you need to achieve. It sounds like you need int.from_bytes() and/or int.to_bytes but without an example it's hard to be sure.

@jc508, what sensor are you porting to?
