Hi I have the Artik 710 and it’s powered by a battery and I was wondering how I could use the cw2015 to get the current charge level of the battery.
Thanks!

I found one resource that tries to suggest using a symbolic link to the cw2015, however this device is not listed on the artik 710.
Do we need to mount specific drivers to use all the i2c devices available?
The original link for this ebook is here.
So I was able to see the cw201x driver with
root@ff4d8ca:/usr/src/app# ls -la /sys/bus/i2c/drivers/cw201x/
total 0
drwxr-xr-x 2 root root 0 Jul 30 19:22 .
drwxr-xr-x 13 root root 0 Jul 30 19:22 ..
lrwxrwxrwx 1 root root 0 Jul 30 19:22 8-0062 -> ../../../../devices/platform/i2c@8/i2c-8/8-0062
--w------- 1 root root 4096 Jul 30 19:22 bind
--w------- 1 root root 4096 Jul 30 19:22 uevent--w------- 1 root root 4096 Jul 30 19:22 unbind
Then I figured out if I change up a bit what the book (quote above) says and do
root@ff4d8ca:/usr/src/app# ls -ls /sys/devices/platform/i2c\@8/i2c-8/8-0062/
total 0
0 -r-------- 1 root root 4096 Jul 30 19:23 charger_status
0 lrwxrwxrwx 1 root root 0 Jul 30 19:23 driver -> ../../../../../bus/i2c/drivers/cw201x0 -r--r--r-- 1 root root 4096 Jul 30 19:23 modalias
0 -r--r--r-- 1 root root 4096 Jul 30 19:23 name
0 lrwxrwxrwx 1 root root 0 Jul 30 19:23 of_node -> ../../../../../firmware/devicetree/base/i2c@8/cw2015@62
0 drwxr-xr-x 2 root root 0 Jul 30 19:23 power0 drwxr-xr-x 4 root root 0 Jul 30 19:23 power_supply
0 lrwxrwxrwx 1 root root 0 Jul 30 19:23 subsystem -> ../../../../../bus/i2c
0 -rw-r--r-- 1 root root 4096 Jul 30 19:23 uevent
Then if i do to get charger status
root@ff4d8ca:/usr/src/app# ls -ls /sys/devices/platform/i2c\@8/i2c-8/8-0062/charger_status0 -r-------- 1 root root 4096 Jul 30 19:23 /sys/devices/platform/i2c@8/i2c-8/8-0062/charger_status
I need to quickly charge some batteries to try this out!
