P22 Drivers

[vjapolitzer]

Hello,

Thanks for all our amazing work on this! I successfully got it running on a P22 (P22B?)! However, touch (and possibly accel) are not quite working right. The driver that works the best for touch is the 816 driver, but taps are not recognized, only swipes and long presses. It also wakes from a down swipe.
I think the touch controller IC may be the 716S or something like that? I took apart the watch to get a closer look at its components.

Raise to wake does not work for either BMA421 or SC7A20 driver. Maybe I am misunderstanding how that is supposed to work. I can take a closer look if the pinout is changed or something, let me know!

FCC also has some nice photos of the inside: https://fccid.io/2AGFWP22/Internal-Photos/Internal-Photos-4786333

Best,
Vincent

thank you very much for all the info, I have a p22 coming and will try to see what is different.

three p8s came this week, all ton, all working, it seems that only utelite store from ali has the non compatible ones until now, maybe I spoke too soon about end on line for the p8.

I had one too

SPIFLASH pin_sck D2 pin_mosi D3 pin_miso D4 pin_cs D5

D15 BTN1 D16 VIBRATE D19 Charging(BAT)

D22 BackLight

and no led pin

thank you very much

so it uses d15 for the button and only uses d22 for brighntess, d14 and d23 are not used?

Sorry I don't know how to detect pin, but the touch IC is cst816 when I opened it

is the side button working on your p22b? it is on a different pin on the p22 it seems, d15 instead of D17 for the p8.

No, it is not working. When I get a chance I can pop mine open again and check the pins.

thanks, use this image, it makes the button work ok. Also reload the init file (p8 core), the watchdog was static to d17, it is now changed to BTN1.

It also wakes from a down swipe.

this is a feature, but only works on controllers that auto sleep. So it is nice that yours wakes up with a down gesture, only first gen p8s do that.

but taps are not recognized

if you have some time, reload the handler(select 816- restart after upload) file from https://enaon.github.io/eucWatch/p8-testing and connect to the watch using the ide: https://www.espruino.com/ide/

it will spill out the touch values on the left side, if you can please upload the output on a tap.

The new espruino image does indeed make the button work!
Here are some outputs from the IDE:

// Four taps

Thank you. Please reload the handler, taps should now work.

ps. sorry about closing the issue, it was by mistake.

[vjapolitzer]

Excellent - taps are working great, thanks! Additionally, since now I am able to toggle the raise-to-wake function, I can confirm SC7A20 driver is working with my P22.

[enaon]

very nice, can you please post a link of where you got it from?
