// scaling from AccNick, AccRoll -> Attitude in deg (approx sin(x) = x),

// the value is derived from the datasheet of the ACC sensor where 5g are scaled to vref

// therefore 1g is 1024/5 = 205 counts. the adc isr combines 2 acc samples to AdValueAcc

// and 1g yields to AdValueAcc = 2* 205 * 410 wich is again scaled by ACC_DEG_FACTOR

// that results in 1g --> Acc = 205 * 12 = 2460. the linear approx of the arcsin and the scaling

// of Acc gives the factor below. sin(20deg) * 2460 = 841 --> 841 / 20 = 42
