I want to make a calibration setup for BLDC ESC in the simulink model. I'm using arduino mega (3,9,10,11 pins) and quatro 30Ax4 esc. Normally I can set it to it's max, min, and incrementally increase/decrease duty cycle with transmitter throttle signal by mapping (1000,2000,160,255) and there is no problem. But when I try to map it 0,255 it doesnot work (sounds every 2 seconds like a throttle signal is abnormal).
I need two suggestions;
1. why I cannot map the signal on the full range (0-255).
2. is it possible to make calibration by just sending the max and min values such as shown in the figure instead of using any mapping techniques?
