Jc2020 Posted March 1, 2021 Share Posted March 1, 2021 I have a NanoPi Neo and I'm currently looking to find out if the I2S pins can be set up as basic GPIOs? I can't find their names, (i.e. PA17) so not sure where to even begin with regards to tinkering the kernel. Any help appreciated! http://wiki.friendlyarm.com/wiki/images/c/c4/NEO_pinout-02.jpg 0 Quote Link to comment Share on other sites More sharing options...
Igor Posted March 1, 2021 Share Posted March 1, 2021 Pins can be reused. It should work this way: https://linux-sunxi.org/GPIO#Accessing_the_GPIO_pins_through_sysfs_with_mainline_kernel 0 Quote Link to comment Share on other sites More sharing options...
Jc2020 Posted March 2, 2021 Author Share Posted March 2, 2021 (edited) Thanks @Igor I saw that page before. But I'm not sure which GPIO number the I2S pins would be. The image below is the best source of information I am able to find for GPIOs. Any tips on figuring this out? Thanks for your feedback.
