Hi,
since you did not enable discussions (Settings > Features > Discussions) I have to enter my question as an issue.
I want to solve the problem, that the servo signal goes LOW at the time of detach() see output below.
Is there a way to get the current state of the I/O pin used for servo output.
On AVR platform I can use digitalRead() but on ESP32, this does not work, it stops the program.
If I connect the pin to another and use the othes as input the program works well and output:
Attach servo at pin 5 and move to 0 -> 180 -> 90 degree
Connect servo out pin 5 to monitoring in pin=18
Each character is 50 microseconds
Move servo to 180 degree, wait 400 ms and then detach 600 microseconds after start of pulse

Move servo to 180 degree, wait 400 ms and then detach 2500 microseconds after start of pulse

Or is there a way to read out the timer counter value and to decide if it is lower than hpoint, which I can get with https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/ledc.html#_CPPv415ledc_get_hpoint11ledc_mode_t14ledc_channel_t ?
