I2C Tool for Jolla
 
Jolla I2C tool


NOTICE:
Devaamo has lots of unassembled myhalf PCBs (maybe some component-kits too).
Please approach them if you need only one (or two)
Clip to attach Devaamo board (0.8mm) can be printed from this STL file:
https://github.com/kimmoli/myhalf/bl...-clip-08mm.stl

NEW Devaamo modified design V1.20 in my github now
https://github.com/kimmoli/devaamoMyhalf

The tool for probing and debugging I2C bus of Jolla.

Installer package: Download here

Source code: github

http://talk.maemo.org/images/icons/icon4.gif Since 1.0.4.20 i2ctool can be started from application launcher icon (and does not need root-rights)

I2C addressing used is the correct 7-bit (so don't mind the read/write bit)

https://lh3.googleusercontent.com/-7...0109215224.jpghttps://lh5.googleusercontent.com/-Z...0109222521.jpghttps://lh6.googleusercontent.com/-x...0109214808.jpghttps://lh6.googleusercontent.com/-J...0109214739.jpg


If you start i2ctool from command line, it provides messages also there.

Code:
Vdd set OK
probing /dev/i2c-1 address 38: read failed
probing /dev/i2c-1 address 39: read failed
probing /dev/i2c-1 address 3a: read failed
probing /dev/i2c-1 address 3b: read failed
probing /dev/i2c-1 address 3c: device found at address 3c
probing /dev/i2c-1 address 3d: read failed
writing to address 3c: a5 00 55
write ok
reading from address 3c count 2
read 41 41

Re: I2C Tool for Jolla
 
I was wondering... can the GPIO pin be pulled up/down via software? I'll probably need that kind of functionality at some point. And btw, this tool is great for debugging :)

Re: I2C Tool for Jolla
 
GPIO... hm... at least it didn't complain anything when setting direction as out and writing a value.
have to check does it really toggle state of the pin.

If it does, i can add control of it to the i2ctool.

ok. GPIO (INT) seems to work as output.

Code:
echo 67 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio67/direction
# changing direction will set output to low
echo 0 > /sys/class/gpio/gpio67/value
echo 1 > /sys/class/gpio/gpio67/value
Picture below is from making pulse from command line
echo 1 > value ; echo 0 > value


and the other one is from setting it back to input, it goes "slowly" up as it is pulled high with pull-up resistor.
echo in > direction

Re: I2C Tool for Jolla
 
Very much appreciated. I have just ordered a set of these. if I can invest the time for tinkering, I will report back with anything I am able to discover.

Most of the time I'm just a wanna be tinkerer, but I have 3 Jollas waiting for my itching fingers...

Re: I2C Tool for Jolla
 
Any chance you have any extra ones to sell? I would rather buy just 1 and not 3. I live in espoo too so if you're willing to sell one we can meetup.

Nothing inside phone. At least nothing found in the scan.

Simple clip to hold the PCB in place - this is for 0.8mm pcb.

Boards were success at Jolla Hack (½) Day in Tampere 22 Feb 2014 Organized by Devaamo, Seravo, ArchRed.

Over 30 pcs were handed over to tinkerers.

Wan't to get one -- (unassembled, sorry) -- see first post.
-- or attend next hack day soon

I think we got 4 pcs assembled and tested, and with one we interfaced with barometric pressure sensor quickly and it worked.

Re: I2C Tool for Jolla
 
this one has a giant keep-out area at the nfc chip, or is it just for tinkering?

edit:
i think in future OH development it is a really good idea to make an eagle -or whatever- file for the NFC chip, basicly a giant keep-out area on both sides and a silkscreen with where to stick it. maybe a giant sticky with tips, hints, practical stuff and files?

No NFC keepout here. But it will be in V1.21 -- soonish :)

I'm not (yet) in hardware development development but is it possible to somehow connect a serial device (ps/2 powered, 5v) to your interface?

Afaik, i2c is not compatible ps/2. You'll need a converter (I did a fast search, didn't find any simple solution) or select a device which supports i2c. Another solution is to use SPI device if i2c supported devices aren't available and use some converter chip to make it work with i2c.

News

New version of i2ctool (0.3) is now available at OpenRepos, https://openrepos.net/content/kimmoli/i2c-tool

hopefully soon also at Jolla store, it will go through thorough testing by QA first.

Short users-guide is also available for download, https://app.younited.com/?shareObjec...2-464ebc35c4b0

Updated MyHalf V1.20 also available from OSHPark https://oshpark.com/shared_projects/6TWMNB35

Hello Kimmo

I'm very interested in getting a v1.2 Myhalf for my Jolla. I can see that it is possible to order a V1.1 from OSH Park but see that this isn't the latest version.

I've tried downloading the the v1.2 files in your GitHub but these don't seem to be Eagle files and aren't accepted by OSH Park.

Can you suggest how I can get a copy of the v1.2 myhalf board please??

Many thanks

Mike

(PS I would use a v1.1 board but i'm not sure if you replaced it because it didn't work or just because v1.2 had bigger pogopins?

the .brd -file is the one accepted by OSHPark, and it uploaded wo issues. Now shared there --> https://oshpark.com/shared_projects/6TWMNB35

The cam (gerber) files you can use to order from e.g. itead.

There aren't any big problems with v1.10. pogopads are little missaligned, and small - fixed in v1.20

Also v1.20 has place for SMD pinheader.

I don't know did someone order a batch of these (and could have extra one)? - I don't have any left.

Thanks.I've just noticed the link you included to the V1.2 file on OSH Park and will try this instead. In the meantime I ordered a 1.1 version which I now regret...

It's not THAT bad :rolleyes: I still use it myself.

I added STL files of printed clips also to the devaamoMyhalf -repo.
This one is suitable for 1.6mm pcb from OSHPark: https://github.com/kimmoli/devaamoMy...clip-1_6mm.stl

Perhaps in two varieties, just the plastic cover and the plastic cover plus a universal PCB with the connectors at the right places. Perhaps even a third variety, same as #2 but with the I2C chip and some Arduino or whatnot soldered on.

Hello Kimmoli! I know you are kinda busy right now, but i can no longer start i2c-tool from terminal. "Failed to create display" 1.1.2.16 yliaavan.
Thoughts?

Re: I2C Tool for Jolla
 
You dont need to run it as root anymore.
But you need to say this as root after attaching the otherhalf, if you need to access EEPROM.

Code:
echo toh-core.0 > /sys/bus/platform/drivers/toh-core/unbind
