pwm cannot set Hz

[shiosalt]

Issue
pymycobot' PWM function cannot set Hz. So I cannot use my servo for my self-made grip. My servo needs 50Hz. By my analysis, PWM 's frequency is fixed in about 1.8KHz.

To Reproduce
run python script below

from pymycobot.mycobot import MyCobot GPIO_Pin_No=23 PWM_channel_No=0 PWM_Duty_Cycle=128 # 50% mc = MyCobot('/dev/ttyUSB0') mc.set_pwm_mode( GPIO_Pin_No, PWM_channel_No) mc.set_pwm_output(PWM_channel_No , PWM_Duty_Cycle)

Expected behavior
for example,

from pymycobot.mycobot import MyCobot GPIO_Pin_No=23 PWM_channel_No=0 PWM_Duty_Cycle=128 # 50% PWM_Freq=50 # Hz mc = MyCobot('/dev/ttyUSB0') mc.set_pwm_mode( GPIO_Pin_No, PWM_channel_No) mc.set_pwm_output( PWM_channel_No , PWM_Duty_Cycle , PWM_Freq)

Atom2.6 should be ok.

I upgraded Atom to 2.6, but it doesn't work. I think it's a pymycobot issue, not an atom issue.

python command's output: >>> mc.set_pwm_output( PWM_channel_No , PWM_Duty_Cycle , PWM_Freq) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: set_pwm_output() takes 3 positional arguments but 4 were given

And, Atom 2.6 doesn't work with 2 args nor 3args either. set_pwm_output( PWM_channel_No , PWM_Duty_Cycle) set_pwm_output( PWM_channel_No , PWM_Duty_Cycle,PWM_Freq)

Atom 2.6 whether can work with 2 args?

[shiosalt]

Unfortunately, Atom 2.6 cannot work with 2 args. I tested 2 times.

I guess Atom 2.6 needs 3 args, but pymycobot sends only 2 args.

*Transponder app send "FE FE 04 64 (PWM_channel_No) (PWM_Duty_Cycle) FA" on set_pwm_output(PWM_channel_No , PWM_Duty_Cycle), and Atom 2.6 doesn't make waves. Atom 2.5 makes waves.

OK, I see. Atom 2.6 does need three parameters, but it's not open to me yet, so I can't improve pymycobot. When atom solves this problem, I will also update pymycobot。
