help PWM input don't work

Postby fahdovski » Mon Jul 06, 2015 12:48 pm

Hi all,
I'm able to connect to the Qground and change RPM with the interface using an FTDI.
But i get the red blinking led when i'm in PWM mode. I'm sending standard 1-2ms 100hz Pwm signal. I checked it with an oscilloscope. I'm powering the ESC via 5v of the FTDI connected to PC.
Please need your help i do not understand the problem here.
Thx

Do you have a servotester?

Hook it to the ESC32 PWM connectors, power up and you can run the motor.
Otherwise let me know what exacly you want do with what connections.

Cheers

Solved by setting min throttle at 1050us for a 1000us pwm signal measured with oscilloscope
