Remember that you need two signed bytes for each angle. Just use the Windows calculator, multiply your result with 256 and convert the number into hex. Examples: 0_degrees: ; 0.556666666667 [Vx = 20/60 * cos(0 * (PI/180)) * 1.67] This should be converted into: 0, 143 (rounded) 180_degrees: .byte142 ; -0.556666666615 [Vx = 20/60 * cos(180 * (PI/180)) * 1.67] This should be converted into: 255, 114 (-1, -142) Have?fun!
