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:

NEW Devaamo modified design V1.20 in my github now

The tool for probing and debugging I2C bus of Jolla.

Installer package: Download here

Source code: github

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)




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
