  • How can I disable usb-autosuspend for a specific device?

    - by black_puppydog
    This is related to the issue discussed in this question. Summary: the mouse freezes when operating on battery since it is autosuspended after a certain time and needs more time to wake up. Disabling usb-autosuspend for the mouse's receiver in powertop is a temporary solution but does not survive a reboot. How can I permanently disable the usb autosuspend for only one specific device? A solution that does not involve installing additional packages is preferred (after all, I want to disable something) but not required. Removing powertop (which seems to be a solution for some) is not what I want - I like poertop... And installing laptop-mode-tools to disable usb_autosuspend alltogether is not what I want, either, thus the new question. Also: will this affect the battery of my notebook? The logitech unifying receiver for the mouse stays connected all the time, so if that prevents the autosuspend from happening for all devices that would probably be bad.

  • Micromax 3G mobile internet modem not being detected

    - by arjith
    I have Micromax 3G modem, and i inserted it in the USB port, but it is not being detected by Ubuntu 12.04, that i'm using from a Live USB. I tried creating a mobile internet connection, however, eventhough i created it, there is no option to connect. I had previously used 11.10 Ubuntu, and it had automatically detected the datastick modem and asked me to create a connection. On typing lsusb in the terminal it gives the following: **Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:0024 Intel Corp.

  • SD card initialization SPI

    - by Openavr
    Hi People I saw a lot of infos about MMC/SD cards and I tried to make a lib to read this.. (modifying the Procyon Avrlib) But I have some problems here. I Don´t change the original code and tried here. My problem is about the init of SD card. I have 2 here, a 256mb and another 1GB. I send the init commands like this order: CMD0, CMD55, ACMD41, CMD1 But SD 256mb returns me only 0x01 response for each command.. the CMD1 i send a lot of times, SD 256mb always returs only 0x01.. never 0x00. The SD 1GB is more crazy... CMD0 returns with 0x01 ..nice but the CMD55 response with 0x05... another times responde with 0xC1... and another ones response 0xF0 with a 0x5F in the next interation... Around internet have infos and examples, but a bit of confused. Here in my project, I must use 1GB card and I´m trying with a MicroSD with a SD Adapter (I think that this is not the problem). Please any help are apreciate! Regards PS - my problem like the problem from this guy http://stackoverflow.com/questions/2365897/initializing-sd-card-in-spi-issues but his solution don´t solved my problem.. The SD1GB returns only 0x01 ever... :cry:

  • Flash Player - green box with version number

    - by Gavin
    I'm trying to get a very simple Flash video working using SWFembed, and it does work across multiple computers at this point in multiple browsers, but as soon as I pushed it live I got this: http://cl.ly/1EDS I've adjusted file permissions, but it is exactly the same code and files as in another directory on the server. I've seen this a few times (green box with version number), but have not been able to find any reference to it online. Thanks for any suggestions in advance!

  • Accessing the MSP and PSP registers of the Cortex-M3 in C/C++ code using Keil's µVision

    - by Captain NedD
    I need to access the MSP and PSP registers (the main and process stack registers) of the Cortex-M3 processor. I'm writing in C/C++. The µVision and associated compiler doesn't let you do inline assembly for this Thumb-2 only core (and I'm not sure that'd be such a good idea anyway). I need to do this so that I can extract the immediate value of an svc instruction regardless of whether it was executed while in thread or handler mode. Thanks,

  • STM32 Compiler/Debugger Chain?

    - by Nate
    I'm starting a project with a STMicro STM32. I've done the Google searches, looking for solid compiler/debugger chains but would prefer answers with success stories. Open Source Compilers/Linkers would be ideal, I just don't know if their STM32 toolchains are stable yet. (Both C, C++ compilers are acceptable). -- So commercial options are acceptable as well. Do any of you have useful suggestions?

  • Can't get my Blue Snowflake Mic to work

  • How to make a product catalog in C#?

    - by Ervin
    I need to develop a product catalog (about 4000 products) application, which would be given to clients on CD or DVD. The catalog exists in webpage format using PHP and MySQL. IMPORTANT: the application is given to clients who maight have old PC, old System. For minimal requirements I would put Windows XP and Internet Explorer 6 (if needed). I need the following features: 1 search option (after productID AND after keyword) 2 print option (by selecting multiple products) 3 shopping cart (making a list which will be sent to an email address if there is any Internet Connection on the computer) When I was asked to do it I had 2 days to realise a very basic version, so I took the whole website and exported it in HTML pages, and developed an application in C# which contains an embeded browser. So the whole website is now static and put on a CD. Everything fine so far. Now here are the problems: 1. the search option was realized by parsing the html files and reading the productID or looking for keywords inside of them. Put on a CD it was extremely slow (searching in 600MB of html files). FOR THIS I WOULD NEED A SOLUTION WITH A STATIC DATABASE (USING ACCESS OR SOMETHING) TO HAVE INDEXED ROWS, SO THE SEARCH COULD BE A VERY FAST ONE. 2. the printing option was a simply call of the embeded Internet Explorer print functions. Here are two problems: a) user needs IE7 for printing the website scaled (FIT TO PAGE), otherwise the edges of the page are cut down. b) users of this app does not have even the basic PC usage skills, so they can't set the printing settings, so there will appear in header and footer the page numbers and titles. QUESTION: can I set these settings from CSS for printing? 3. couldn't make a a shopping cart as I don't use a database, so I have static websites and content is inside the HTML. QUESTION: WHICH ARE THE BEST SOLUTIONS FOR THE PROBLEMS DESCRIBED ABOVE? PLEASE ANSWER EVEN IF YOUR ANSWER IS FOR ONE QUESTION ONLY. THANKS

  • ARM cortex: mutex using bit banding

    - by Jeff V
    Given that, on the ARM Cortex M3, I can: atomically read a single bit atomically set a single bit atomically clear a single bit How can I combine these for a mutex style set of operations: try lock take lock release lock It seems that try_lock or take_lock would require two operations that would not be atomic. Do I need more control to accomplish this? Disable global interrupts would do it but it seems there should be a more surgical approach.

  • AVR Analog Comparator + Internal Pullup?

    - by vicatcu
    I have what I hope is a simple question pertaining to the Atmel AVR microcontrollers. So I want to use the ATTiny85's Analog Comparator to determine if a signal is above or below a threshold. This signal is normally "floating" and grounded when "active" (i.e. it's an active low - open collector signal). If I enable the pullup on the input pin (which is also the comparator input) by doing: DDRB = 0x00; // DDRB.1 = 0 = input PORTB = 0xFF; // PORTB.1 = 1 = internal pullup enabled If i use the analog comparator and select PORTB.1 as AIN1 will the internal pullup be applied to my input signal? I'm hoping someone has personal experience to verify this behavior. Hope this question isn't too 'hardware-oriented' for stack-overflow. Thanks!

  • GUI-Library for microcontroller

    - by Martin Kirsche
    I want to create a GUI driven application for a micro-controller (Atmel XMEGA) that is connected to a 128x64 dots graphics LCD (EA DOGL128-6) and 4 buttons for navigation. Controlling the display itself (e.g. drawing pixels and characters) is no problem but in order to prevent me from reinventing the wheel I was googling for a GUI-Library/-Toolkit that is written in c, includes its source code, will run on a 32 MHz 8-bit micro-controller and provides at least the following controls: panel (to group elements) menu (scrollable) icon label button line-graph (optional) But I didn't find any thing useful. Does anyone know (or better uses) such a library(preferably for free)?

  • Advice on a DB that can be uploaded to a website by a smart client for collecting survey feedback

    - by absfabs
    Hello, I'm hoping you can help. I'm looking for a zero config multi-user datbase that my winforms application can easily upload to a webserver folder (together with 1 or 2 classic asp pages) and am looking for some suggestions/recommendations. The idea is that the database will be used to collect feedback entered by people filling in the asp pages. The pages will write to the database using javascript. The database will subsequently be downloaded again for processing once the responses are in. In Summary: It will mostly run in MS Windows environments. I have a modest budget for this and do not mind paying for such a database. No runtime licensing costs. Should be xcopy - Once uploaded to a website folder it should be operational. It should not have a dotnet CLR dependency. It should support a resonable level of concurrent access. Average respondent count would be around 20-30 but one never knows. Should be a reasonable size so that uploads/downloads to and from the site will be reasonably fast. Would appreciate your suggestions/comments Many thanks Abz To clarify - this is a desktop commercial application for feedback management in a vertical market. It uses SQL Server as the backing store. The application currently provides feedback management from email and paper feedback. I now want to add web feedback capability. Getting users to to make their SQL servers accessible to a website is not at option at this time as I am want to make getting up and running as painless as possible. I intend to release a web based implementation of the software in the near future but for now am looking at the above as a pragmatic way to provide web based feedback collection.

  • Would a multitouch capable PC allow me to do Android development simulating the touch UI without an Android device ?

    - by Scott Davies
    Hi, I recently purchased a Samsung Galaxy Tab as a reference implementation (phone and first gen Android tablet), of Android 2.x for app development. I have noticed a slew of Android 3.0 slates being talked about at CES 2011 (Motorola XOOM, etc.). If I had a multitouch PC with the Android SDK/Emulator on it, would this allow me to more closely approximate device simulation by allowing user input via the multitouch screen ? Would it work via touch just like Windows 7 recognizes touch as mouse style input ? Has anyone done this ? Thanks, Scott

  • need a web browser in my desktop application

    - by javadahut
    part of the specification of this desktop application is to have a mini browser built in, so that you can enter URL, and navigate the site as you would on a normal browser. Access to the browser page's DOM is required, should let me programmatically change the rendering view of a page, should be cross-platform, renders javascript JDIC seems outdated and I've heard Mozswing doesn't run on Mac.... Jxbrowser license costs a grand and up. Is Java the wrong platform to be creating such app? Are there any other solutions out there for building an application like this ? Thank you.

  • Is using Natural Join or Implicit column names not a good practice when writing SQL in a programming

    - by Jian Lin
    When we use Natural Join, we are joining the tables when both table have the same column names. But what if we write it in PHP and then the DBA add some more fields to both tables, then the Natural Join can break? The same goes for Insert, if we do a insert into gifts values (NULL, "chocolate", "choco.jpg", now()); then it will break the code as well as contaminating the table when the DBA adds some fields to the table (example as column 2 or 3). So it is always best to spell out the column names when the SQL statements are written inside a programming language and stored in a file in a big project.

  • Hex Decompilers for PIC

    - by Chathuranga Chandrasekara
    I've faced to a problem with a PIC Micro controller. I have a micro-controller programmed by me long time ago and I lost the relevant source code and the schematic diagrams. Now I need to invert the value of a port. I can do this using some NOT gates but it is a big hassle to do so. or alternatively I will need to write the whole program back. I don't expect to see the code back in PIC C or MikroC. Having an understandable assembly code would be sufficient. So do anyone has any experience on a good HEX decompiler that I can use for this purpose? Any comments based on your experience? :)
