<set_>
The i2c call for 16 bit addressing via smbus does not allow 16-bit addressing from the kernel source.
<set_>
Oh!
<set_>
I know...I can add the two u8 structs?
<zmatt>
16-bit addressing? what do you mean by that, and why do you think you need it?
<set_>
oh. I thought this chip handles 16-bit addressing.
<zmatt>
why are you even trying to do anything in C?
<set_>
I am not.
<zmatt>
then why did you copy/paste a snippet of a C header?
<set_>
Proof.
<zmatt>
??
<set_>
Ha.
<zmatt>
proof that you're confused? yeah
<set_>
Yes, of course.
<set_>
So, the issue is that this chip, the PCA9685, does addressing a bit differently compared to what smbus2 allows b/c of the kernel source.
<set_>
Right?
<zmatt>
???????
<zmatt>
no
<set_>
Oh.
<zmatt>
it uses i2c in the most normal, mundane way possible
<set_>
I was reading the errors/issues in the smbus2 repo. It seems that is what this fellow is saying.
<set_>
Oh.
<set_>
So, nothing out of the ordinary?
<set_>
Okay.
<zmatt>
and you have code for it already, which I wrote for you :P
<set_>
Then, why am I not in control of my i2c addresses at 0x34 or 0x54?
<set_>
Or...do I need to use an offset?
<zmatt>
I have no idea what you mean by that
<set_>
Well, from the BBB standpoint, it is open.
<zmatt>
?
<set_>
i2c-2 is open and I cannot change that option.
<zmatt>
?
<set_>
What is it that I am saying that makes this so difficult?
<zmatt>
I have no idea what the words you're typing could possibly even mean
<set_>
Fine.
<set_>
I will retreat.
<zmatt>
like, all I can gather from what you're saying is that something is not working for you
<set_>
Right
<set_>
So far, your source does not work (no matter how I change and alter it).
<set_>
I tried w/ what i2cdetect detects and what the datasheet states is the address of the Cape.
starblue has quit [Read error: Connection reset by peer]
<zmatt>
no changes should be needed, you're probably just breaking things
<set_>
Fine. Okay. No issue.
<set_>
If something is done outside of...forget it. You are right. This should be an easy out for me.
<zmatt>
if it's a cape with this thing there might be a kernel driver active for the device though, which means you can control the leds via a pwm interface or a led interface probably
<zmatt>
or if you want to control it directly using i2c, disable the cape overlay
<zmatt>
this is just a guess though
<set_>
Okay. I will look into it.
<set_>
I tried the older way of adding the uboot overlay.
<zmatt>
I'm still trying to guess what you could possibly mean by the things you've saide
<zmatt>
*said
<zmatt>
I don't know what you mean by that but it's probably bad
<set_>
I added the BeagleBoard-DeviceTrees uboot-overlays for the BBORG_SERVO-00A2.dtbo.
<set_>
It broke the board in specific ways, e.g. cannot reboot into the working system.
<set_>
Is there a way uboot controls this Cape functionality?
<set_>
Is so, I will go that route and test it.
<set_>
I will go and check.

NULL?
<set_>
Anyway, no issue.
<set_>
Try, try, and try again is all I can do!

it is too bad that uboot and github have not figured out how to allow hyperlinks in .dts files and .dtsi files.
<set_>
For instance, I look up am335x-boneblack.dts but the preprocessor directives are unclickable.
<set_>
I need like three screens. Blah.

Does the ServoCape not have the inputs already placed and seated?
<set_>
I mean, are the input pins already soldered on?
