To whom it may concern:
I have downloaded sample projects code from the website https://github.com/quic/sample-apps-for-Qualcomm-Robotics-RB5-platform. In GPIO-samples, when I run 5. Simple PWM output code, I don't know in which GPIO port can I get the PWM signal, so that no PWM signal can be detected when the PWM parameter is changed. Can anyone tell me which is the default output GPIO port of PWM?
In addition, when I set the second parameter of PWM to 1 (namely,/qrb5165_platform -pwm 1 1000 500), there will be a parameter error. When the second parameter of PWM is set to 0 (namely, /qrb5165_platform -pwm 0 1000 500), the code can be run.
Why would this be?
Any advice would be really appreciated. Thanks.
