I have the same issue with GPIO 11 and GPIO 3. any special caution that's needed for these two GPIO pins when controlling by Python?
GPIO 11 is marked as a GPIO on the pin layout diagram (1.2) but not possible to control via the GPIO App (Omega2+ view) that comes pre installed. Is there anything special with GPIO 11?
For GPIO 3, it's in GPIO mode as it is when booted.
Thanks for your explanation! In the table of Pins that needs to be floating, GPIO7 anf GPIO8 are mentioned, although those pins are not marked as GPIO pins in the pinout diagram. Is this just a phrasing error, or are the wrong numbers stated?
Also about the floating input pins during boot mode, and please excuse my me for still being early at the learning curve, this only applies to input pins right? How do I set these pins as output pre, or during, the boot sequence?
A more specific question for my specific case, and don't hesitate to ask me to move this to a separate question if you think I should: If I connect an (intended) output pin to a NPN transistor gate over some 1k resistance, and connects the emitter to ground, is the pin considered floating or not? Can I hard wire this setup to GPIO1 and still boot up the omega?
I think this is a good question, and the documentation is quite confusing to me.
GPIOs 7, 8, and 9 cannot be used as regular GPIOs - So what kind of GPIO's can they be used for? Are they General Purpose I/O or not?
Documentation also starts with stating that "The Omega2 has twelve General Purpose Input/Output pins", but there are 21 I/O's marked with green on the pinout diagram, and the legend states that green in GPIO.
If I want to maximize number of Output pins, how many can i get? (I would need 14 to avoid using Shift Registers...)
If I want to maximize number of Input pins, how many can i get?
I started to install a package using opkg but the installation failed due to not enough available space on file system.
Now I cannot remove it and reclaim the disk space occupied by the installation files. Where is opkg storing temporary files for installation?
My installation ended with:
Collected errors:
* verify_pkg_installable: Only have 420kb available on filesystem /overlay, pkg libdb47 needs 440
* opkg_install_cmd: Cannot install package python3.
If I try to remove i, it's not there:
root@Omega-4E95:~# opkg remove python3
No packages removed.
df looks like this:
