PWM and Analog Read Support

I am developing a robot application on the Up Board and am wondering if there are any existing CPP/Python libraries for PWM read/write for this board that are comparable to the RPi.GPIO library available for the Raspberry Pi boards. No point reinventing the wheel right?

From my experience using the /sys/class/pwm/pwmchip# can only write PWM however not read one in return. So my approach would be to use an interrupt based method to measure the duration of the pulse high through the /sys/class/gpio interface.
