Unable to create directory in /usr/share

Asked 2020-Dec-02 at 13:05

I have heard its a conventional practice to store program dependent files in /usr/share/application-folder in linux. So I'm trying to do it in my c program in a function called load_interface_files() for example. I am not sure if this is a good practice or not, I've heard about creating configuration files for this kind of issues.

Anyways, here's the the code I wrote to make a directory in /usr/share.

use ls -ld /usr/share to see what the permissions on the directory are (without -d, you get the contents and their permissions).

Use code like:

You have to install the "Desktop Video" software for Linux, which supports x64 and i386 (but no arm). It will provide DeckLinkAPI.h and udev should create the video device in /etc automatically.

B&R get drive serial number via MC_BR_GetHardwareInfo function block

Asked 2019-Feb-20 at 15:29

Never asked a B&R related question here, but I'm trying to retrieve the serial number from a drive using the MC_BR_GetHardwareInfo function block. Since the documentation lacks any kind of example code on this topic I'm getting nowhere.

Which information should I provide to the function block in order to get the desired serial number?

Below sample will crash in the PLC, probably because the function block requires certain pointers to be addressed:

You are probably getting a page fault, because you provide the MC_BR_GetHardwareInfo function block (FUB) a wrong type, which leads to random behavior.

A function block is basically a function which requires a reference to a specific type as parameter. This type contains the actual in- and outputs which are used, internal state variables, etc. We need this, because of the synchronous execution of the code. This means unlike a function, you need to call a FUB until it is done.

Let's take a look to the help of the FUB: Guid: 056444ea-2a15-4af6-a5ae-0675894b17d3

So the FUB needs a reference to the Axis object of which you want to know the HW info and an Execute command. It will give you some status bits, an error code and the actual data you want to have within the structure HardwareInfo of the type MC_HARDWARE_INFO_REF.

First we need to instantiate the FUB by create a variable of its type. We do this in the local *.var file of the task:

QUESTION

How to debug USB HID scancode-keycode translation in Linux

Asked 2017-Nov-10 at 00:07

I have recently converted a 122-key terminal keyboard to USB as a configfs USB gadget (the keyboard portion is using HID codes), it works quite well in except that I cannot seem to get my Archlinux installation to recognize certain HID codes (specifically at the moment F13-F24) and translate them into event codes that I can use in X.

HID codes received properly

I am able to see the HID being received by the computer through /dev/hidraw2 (the output below is when pressing F24, HID code 0x73 based on: https://gist.github.com/MightyPork/6da26e382a7ad91b5496ee55fdc73db2.

Found the problem. After looking through the code for usbhid I realized that it was what was assigning the available event codes discovered by evtest. To do this, it reads through the HID descriptor. As it turned out I had used a generic HID descriptor and the Logical Maximum and Usage Maximum were cutting off the higher numbered HID codes. I used https://github.com/DIGImend/hidrd to get an editable version of my binary descriptor and then changed the Usage Maximum and Logical Maximum to the highest HID code I use. Reconverted it to binary format, uploaded and started the keyboard. Now evtest recognizes all keys.

Here is my original spec:
