NickelMenu: An integrated launcher for Kobo eReaders - Page 63

@akadaedalus: That unfortunately depends on the device, and this only affects powering up/down the chip, which is only less than half the battle (and apparently, doing it wrong breaks Nickel's own handling of it, c.f., https://github.com/koreader/koreader...r.sh#L192-L206 which successfully kills it, but apparently kills it for good

).

c.f., arch/arm/mach-imx/imx_ntx_io.c (or similar, moves around depending on the kernel).

Code:

#define CM_BLUETOOTH_PWR 126

(I haven't looked into this any further)

EDIT: There's a /bin/ioctl binary on Kobo FW, but I have no idea of its provenance and whether it deals sanely w/ by-reference vs. by-value ioctl shenanigans...

May I write a menu label split on more lines? I mean, I would like to force a menu label with higher vertical spacing. I tried with the usual \n \r but they are not interpreted as such. Thank you!

If you think it's non-trivial, and I had suspected that it would be device dependent, I guess I'm not going to be able to come up with an elegant solution. I guess it will have to wait until I have more time to beat my head against the wall.

I looked at the ioctl binary and was stymied by the arguments which didn't really match other examples I found. I think you have to pass data to STDIN.

Thanks for the tips!

For a safe and easy to track example, you can probably play with the frontlight command to test manual ioctl commands against ntx_io (IIRC, the cmd is 241 (do double-check that), and it takes a *value* [0-100], not a pointer).

EDIT: Yup, it's 241

Turns out it's https://github.com/jerome-pouiller/ioctl

.

So, my example above is as simple as `ioctl /dev/ntx_io 241 -v 0` (I *think* the WiFi/BT power stuff also takes a value, not a pointer, but I'm in no position to double-check right now).

Is it possible to create a menu item to open a specific collection/shelf directly?

That worked great for the front light, thank you.

I attempted the similar syntax to match the IOCTL call I saw earlier. Sadly it appears I need more than that.

I'll keep poring through the strace and probably dive in some source code.

ps, I appreciate your efforts. I had the o.g. Sony Libre but when Sony stopped making readers I lived in a world of disappointment with tablet apps and a locked-down Kindle. This thing is fun again.

What's your code for turning on the front light to a specific value? Thanks.

NiLuJe · 01-27-2023, 02:14 PM

Jon, that's is *literally* right in front of you in the quoted section (hint: 0 is a value).

(Keep in mind this will *not* be tracked by Nickel, as most boards don't have a way to actually request the current value from the hardware, so it has to be tracked in userland software).

Yup, it's by value

No, I'd have to implement that separately.

Yes, it's most likely possible, but I don't have time right now.

Please don't spend your time on this. I emulated this by having the same menu line written three times. I have a simple menu with KOReader and a Reboot and want to avoid accidentally pressing the reboot option. This is all right for me.

Another solution would be to have the Reboot menu item in another place, but this one seems the place.

Thank you indeed.

Thanks. Looking forward to it whenever you get a chance.

Is there a way to get the battery percentage to be visible without tapping on the battery icon, first? To be clear, I'm not talking about NickelClock that always shows the time and battery in the header. I'm looking for a way to change the menu that opens when you tap in the middle of the screen. Half the time when I try to tap the battery icon to see the remaining percentage, I trigger the "recent books" list, instead, so I'd rather not need to tap on the battery icon at all.
