Please help. Can't work with PWM on ESC32v3

Postby Masa » Tue Nov 08, 2016 8:29 am

Hi, all
I'm able to connect to the AQ ECU and change RPM with the interface using an FTDI.
But I can't work with PWM from Arduino uno.
Using motor is Hyperion VP Z2209-30.
I'm powering the ESC via 5v of Arduino connected to PC.
I tried a lot of width of frequency, but It did'nt work
I can't understand appropriate frequency of PWM and duty.
Please need your help i do not understand the problem here.

These are parameter in ESC

STARTUP_MODE = 1
BAUD_RATE = 230400 baud
PTERM = 0.500
ITERM = 0.00500
FF1TERM = +3.09656e-09
FF2TERM = +1.16186e-03
MIN_PERIOD = 50 us
MAX_PERIOD = 12000 us
ADVANCE = 15.00 Degs
START_VOLTAGE = 0.75 Volts
GOOD_DETECTS_START = 48
BAD_DETECTS_DISARM = 32
MAX_CURRENT = 1.30 Amps
START_CURRENT = 0.75 Amps
SWITCH_FREQ = 20.0 KHz
MOTOR_POLES = 14
PWM_MIN_PERIOD = 2200 us
PWM_MAX_PERIOD = 25000 us
PWM_MIN_VALUE = 750 us
PWM_LO_VALUE = 1000 us
PWM_HI_VALUE = 1950 us
PWM_MAX_VALUE = 2250 us
PWM_MIN_START = 1100 us
PWM_RPM_SCALE = 11400 RPM
ACTIVE_FREEWHEEL = 1
THR1TERM = +0.00000e+00
THR2TERM = +1.00000e+00
RPM_MEAS_LP = 0.750
SERVO_DUTY = 5.0 %
SERVO_P = 0.050
SERVO_D = 0.000
SERVO_MAX_RATE = 1000.0 deg/s
SERVO_SCALE = 360.0 deg
ESC_ID = 1
DIRECTION = 1
AUDIO_VOLUME = 0.0

Try and change pwm max period to 20000 to allow 50 hz pwm
