How do I address the gpio pins directly through bash or python?

Question

I am currently roadtesting the maaxboard, and i have succesfully used the gpio pins to connect i2c devices; how can I address the gpio pins directly? I want to do the following:

- use a gpio pin as a digital input or output

- use a gpio pin for pwm, if possible

- use a gpio pin for 1-wire sensors

I have made some progress by compiling the wire device driver, including the w1_gpio driver, but I am at a loss how to configure it. In similar devices (e.g. Raspberry PI) this is done by means of overlays, but these aren't available as yet.

Has anyone made any progress in this area?

Hello Josh, this was indeed the answer I was looking for, as far as my first question goes; I had already stumbled on this method by digging in my own memory on using the raspberry pi in the early days before WiringPi.

I am still looking for a way to do PWM on a GPIO pin, and a method of how to implement the 1-wire protocol on a GPIO pin.

Thanks for the help!

Hi, This is how we are currently reccomending accessing and controling the GPIO. Let me know if you need further help! Using the GPIOs. -Josh
