Re: how to use esp32 input capture and motor pwm function?
Posted: Thu Apr 06, 2017 10:56 am
There are two drivers under progress for driving the motors : Basic PWM (bpwm) and MCPWM (Motor Control PWM) . They will feature on the fly frequency and duty changes, they will have sync, capture, fault & dead-time subunits and will also be able to generate the signals for driving bridge driver circuits. This will add 2 BPWM groups (with 4 pwm channels each) and 2 MCPWM groups(with 3 pwm channels each) to the peripherals family. They should be out in the next RC of esp-idfchopin1998 wrote:Hi,
I noticed that datasheet said there are 4 pwm modules with input capture function in esp32, but I cannot find REG desc or code snippet on it.
Somebody used that?
