Hi All
First post here.
Have been using Rpi Zero 2W for a couple of years in various installations and other then speed been happy with it.
So got an Orange Pi Zero 2 W in an attempt to use it as a plug in replacement for the Rpi.
Installed Armbian and other than a booting issue, it all works.
The first obstacle is the i2c, it is obvious that is nowhere near as easy as a Rpi to set up.
I have read many posts and get more confused as the days go on.
So, the question:
Is there a step by step instruction on how to enable I2C.
I am connecting 2 x ADS1115 A2D converters, one at &H48 and the 2nd at &H49.
When I use i2cdetect -l
i2c-0 i2c DesignWare HDMI
i2c-1 i2c mv64xxx_i2c Adapter
i2c-2 i2c ditto
When I use i2cdetect -y 0
&h30 and &h50 show up
When I use i2cdetect -y 1
I get UU on &h36
In software, I can do a
fd = i2c_open("/dev/i2c-0") or use i2c-1
rc = i2cselect (fd,&h48,0)
BUT, I cannot write or read to the device.(obviously because it does not exist according to i2cdetect )
My armbianEnv.txt has
overlays=i2c3 changed from i2c0 after reading some posts.
dtparam i2c_arm=on
In armbian-config /system/kernel/booto001/ I have ticked i2c0-pi and for 2 and 3 as well.
So after all that I have no idea how to proceed.
Regards
EDIT: kern.log has repeated entries as follows:
