Raspberry PI

Default Mapping in the Configuration​

Currently, the configuration.json file contains the default mapping to GPIOs. You have the flexibility to change the input/output settings without impacting anything other than turning GPIOs into inputs or outputs. See the picture below:

The GPIO pins on the left side are configured as outputs, while those on the right side are configured as inputs. You can modify these settings in the configuration.json file under the capabilities section. The numbers listed represent GPIO pins, and FEAGI and RPI will use these pins accordingly.

Current Availability of Input and Output for FEAGI​

At present, FEAGI has the capability to read both input and output. To control the output, it relies on the cortical area's ID called "o_gpio." When you activate a specific voxel within this area, it will correspond to the pin number.

The cortical area responsible for GPIO output is named "GPIO_out." If you select, for example, 2 from the picture above, it will activate GPIO 2 as an output. There is also a cortical area's ID called "idgpio," which displays red voxels based on the data it reads.

Example with LED​

You can utilize various examples available in Raspberry PI tutorials. For instance, I obtained the sample image from here. You can see it here:

The key distinction between tutorials and FEAGI is that you don't have to be concerned about the coding aspect. All you need to do is connect your electronics or follow the provided diagram, as shown above. It will function instantly. You can also plug and unplug in real-time. Returning to the LED example, you connect the positive end to pin 17 (GPIO17) and the ground to the negative end. Then, when you click on the "GPIO_out" cortical area, select the location corresponding to pin 17, and the LED will light up. You can adjust the refresh rate (Hz) depending on how long you want the LED to remain on.

Example with switch button​

Using the image from here.

So, we will need a GPIO 18 and 18 in GPIO_in cortical area. Since this switch button will return False if you press the button, cutting off the electricity, that's how it is set up in the diagram. You can adjust it to meet your needs. FEAGI is extremely flexible for that. So, using the diagram above, you should see a red voxel displaying in the GPIO_in or the ID called idgpio until you press the button, at which point the red voxel will disappear.
