Hello,

Im currently using omega2S with the old style USB-A port in my product.

But people keep asking for USB-C port.

Im wondering if I can use the USB-C connector with omega2S.

If so can someone post a schematic on how to do that?

The speed of USB-C doesnt matter, they just want the USB-C port itself.

Thanks

Hello,

I want to run a shell script after booting openwrt by putting the script into the files folder so that when i build openwrt my scripts are automatically included in the build.

I read that there is a folder called "files" in the root source openwrt build directory (~sourcce/files), anything placed in that folder will get included when you build openwrt.

For example if you put a file in ~/source/files/etc it will appear in the /etc folder when you flash the binary to the onion device.

So I tried that and it worked. The files do appear in there. So I read on this website:

https://stackoverflow.com/questions/33340659/how-to-auto-start-an-application-in-openwrt

That to get a script to run after boot up, I just need to put my script into /etc/init.d folder, then enable that script.

But it seems if i try to type

/etc/init.d/<your script> enable

that enable function doesnt work in the onion openwrt docker for some reason.

It gives an error that it cant open /etc/rc.common

my script has execute permissions and has this in it:

 #!/bin/sh /etc/rc.common
 echo "hello"

Does anyone know how to get a script to automatically run after booting openwrt, and have that script be apart of the build so that it automatically runs after boot after i flash it without having to type any other commands after flashing?

Thanks

Hello, thanks for the info.

So the website says this:

For GPIO18:

omega2-ctrl gpiomux set pwm0 pwm

For GPIO19:

omega2-ctrl gpiomux set pwm1 pwm

For GPIO20:

omega2-ctrl gpiomux set uart2 pwm23

For GPIO21:

omega2-ctrl gpiomux set uart2 pwm23

I notice that for GPIO 20 and 21 it has the same command above, is that correct?

omega2-ctrl gpiomux set uart2 pwm23

Thanks

Thanks for that.

Does anybody know where i can find the source code for the command line program to control the pwm:

"onion pwm ....."

it should be in the docker file for the opwnWRT that is used to build the firmware image.

Anybody knows what path the source code for that command is in?

Thanks

Hello,

I would like to know if there are libraries available (or drivers) to control the PWM hardware from C language? If so can you please let me know how to get it and how to use it please?

Thanks

@crispyoz It only needs to keep track of time when its switched ON. If its switched off and then back on, then it doesnt need to know the time for my application, it only needs to keep track of time if i set the time while it stays on, if its turned off, then it no longer matters.

@crispyoz So there is no way to prevent the code (either the one in the flash, or the one running in memory) from getting read out and recreated?

@crispyoz Thanks for the information. But no it doesnt need to be extremely accurate, just be able to keep track of the time once i set it either by using command line or in code.

Also it wont be connected to any external internet servers, so it cant update the time using that. I just want it to keep a rough estimate of the time using just the Omega2S by itself with no additional hardware or external servers.

For example if i set it to 1AM, and then check the time 1 hr later it should say its 2AM (plus or minus 1 minute or so) would be fine.

Can it do that now without modification?

Hello,

Is it possible to set the time on the omega2s, and it keeps track of the actual time?

For example at the prompt i can type "date" and it gives me some random date, if i set the actual date and time, will it be able to keep the actual real-time and date from then on, until i turn off the power of course.

Thanks

I disabled kmod-mmc and its working now! thanks for your help!
