I want to detect the state of the electric bicycle, such as whether the brake is turned on (high level signal), how should it be connected.

I want to connect the signal of electric bicycle controller (48v) to ESP8266, is it feasible? How should I pick it up.

Hello Sara,
I have been trying to get a 90 degree phase shift on two PWM channels for quite some time… unfortunately without success until now.
The goal is to simulate a two channel incremental encoder. The duty cycle should always be 50%.
Do you have any ideas?
Thanks in advance

Hallo Sara,

I was wondering if you also have a guide on how to read duty cycles from for example a smt172. Would like to read that since your guides are way so clear and this site is my go to site for esp32/8266. Kind regards

Hi
Thanks for following our work.
See if this discussion provides any useful information for what you want to do: https://www.reddit.com/r/esp32/comments/bivbz1/can_a_esp32_read_the_pwm_signal_of_a_rc_receiver/
Unfortunately, we have some work to do on those days. Maybe next year.
Regards,
Sara

Hi Sara,
congratulations for the great work you are doing: you are inspiring many developers with your articles for sure: I am among them.
I would like to ask if you have already explored the reading of an external PWM signal, this could be very useful on many robotic application: I haven’t found anything around and there is no implementation for that in the pwm.h API (Except pwm_get_duty that doesen’t work I belive to read an external PWM signal).
Beside that are you visiting the European Maker Faire in Roma next 8-10 october?
Thanks again
All the best.
L.

Hi Simon.
Thanks for telling me.
I’ll update the tutorial soon.

The analogWrite-Range is no longer 1023 by default. It has been changed to 255.
