How to control the GPIO output? (Metawear CPRO)

nub · March 2017

The c++ API has information about how to read using the GPIO, however there's nothing about changing the output. In the docs I found "mbl_mw_gpio_set_digital_output", however the arguments are the board and the pin to change. How does one specify the output?

Does that funcion set the output to 1 and we have to use "mbl_mw_gpio_set_digital_output" to set it to 0 again?

Another question: There's only 1 PWM pin in the metawear CPRO, right? And is the only way to operate it using the haptic module?

Use mbl_mw_gpio_clear_digital_output to clear the output.

Yes, there is only one PWM pin, controlled with the haptic module.
