But both the https://github.com/Seeed-Studio/grove.py/blob/master/setup.py script as well as various documentation (e.g. https://wiki.seeedstudio.com/Grove_Base_Hat_for_Raspberry_Pi/#usage) prominently mention
grove_pwm_buzzer
.I cannot find
grove/grove_pwm_buzzer.py
it in the current master branch. Only a pull request from some time back. #55 Am I doing something wrong or has the file been deleted for some reason?
