  • linear interpolation on 8bit microcontroller

    - by JB
    I need to do a linear interpolation over time between two values on an 8 bit PIC microcontroller (Specifically 16F627A but that shouldn't matter) using PIC assembly language. Although I'm looking for an algorithm here as much as actual code. I need to take an 8 bit starting value, an 8 bit ending value and a position between the two (Currently represented as an 8 bit number 0-255 where 0 means the output should be the starting value and 255 means it should be the final value but that can change if there is a better way to represent this) and calculate the interpolated value. Now PIC doesn't have a divide instruction so I could code up a general purpose divide routine and effectivly calculate (B-A)/(x/255)+A at each step but I feel there is probably a much better way to do this on a microcontroller than the way I'd do it on a PC in c++ Has anyone got any suggestions for implementing this efficiently on this hardware?

    - by Daniil Harik
    Hello, I know that question with same title has been asked almost 6 month ago. I have Googled for this problem and I have not found any working solution. Has there been any fixes for this very critical problem? I need to get my website running ASAP.

  • How to convert a BufferedImage to 8 bit?

    - by Zach Sugano
    I was looking at the ImageConverter class, trying to figure out how to convert a BufferedImage to 8-bit color, but I have no idea how I would do this. I was also searching around the internet and I could find no simple answer, they were all talking about 8 bit grayscale images. I simply want to convert the colors of an image to 8 bit... nothing else, no resizing no nothing. Does anyone mind telling me how to do this.

  • What is the fastest way to do division in C for 8bit MCUs?

    - by Jordan S
    I am working on the firmware for a device that uses an 8bit mcu (8051 architecture). I am using SDCC (Small Device C Compiler). I have a function that I use to set the speed of a stepper motor that my circuit is driving. The speed is set by loading a desired value into the reload register for a timer. I have a variable, MotorSpeed that is in the range of 0 to 1200 which represents pulses per second to the motor. My function to convert MotorSpeed to the correct 16bit reload value is shown below. I know that float point operations are pretty slow and I am wondering if there is a faster way of doing this... void SetSpeed() { float t = MotorSpeed; unsigned int j = 0; t = 1/t ; t = t / 0.000001; j = MaxInt - t; TMR3RL = j; // Set reload register for desired freq return; }

  • Sinatra / Rack fails with non-ascii characters in url

    - by Piotr Zolnierek
    I am getting Encoding::UndefinedConversionError at /find/Wroclaw "\xC5" from ASCII-8BIT to UTF-8 For some mysterious reason sinatra is passing the string as ASCII instead of UTF-8 as it should. I have found some kind of ugly workaround... I don't know why Rack assumes the encoding is ASCII-8BIT ... anyway, a way is to use string.force_encoding("UTF-8")... but doing this for all params is tedious

  • How do I split up a long value (32 bits) into four char variables (8bits) using C?

    - by Jordan S
    I have a 32 bit long variable, CurrentPosition, that I want to split up into 4, 8bit characters. How would I do that most efficiently in C? I am working with an 8bit MCU, 8051 architectecture. unsigned long CurrentPosition = 7654321; unsigned char CP1 = 0; unsigned char CP2 = 0; unsigned char CP3 = 0; unsigned char CP4 = 0; // What do I do next? Should I just reference the starting address of CurrentPosition with a pointer and then add 8 two that address four times? It is little Endian. ALSO I want CurrentPosition to remain unchanged.

  • How does it matter if a character is 8 bit or 16 bit or 32 bit

    - by vin
    Well, I am reading Programing Windows with MFC, and I came across Unicode and ASCII code characters. I understood the point of using Unicode over ASCII, but what I do not get is how and why is it important to use 8bit/16bit/32bit character? What good does it do to the system? How does the processing of the operating system differ for different bits of character. My question here is, what does it mean to a character when it is a x-bit character?

  • Why does remote desktop connection flash from one PC but not others?

    - by Randy Orrison
    I have 20 PCs (Windows XP) in remote locations connecting to the same server (Windows Server 2003) using Remote Desktop over a VPN. On just one of the PCs the remote desktop screen flashes (redraws) multiple times after connecting, the others don't. The screen resolution is the same: local is 800x600 32bit; RDP file is set to full screen, 256 color; remote when connected is 800x600 8bit color. Any suggestions what the problem might be, or what to investigate next?

  • Virtual terminal with at least 16bit color?

    - by trusktr
    It's 2013 and there should be terminals with more than 256 colors by now (you'd think). Are there any terminals with more than 8bit colors (usually from 8 bit we jump to 16bit) to use with linux? Ideally, I'd like to have a linux terminal with 32bit colors for the foreground and background of each character. So, the functionality would be the same, with escape sequences, but just more of them (or something like that?).

    When i upload my rails app via SFTP to production server which is running Ubuntu 10.04 LTS all cyrillic characters in my files look like this: http://dl.dropbox.com/u/347209/chars.png As you can see, only parts of words are broken. And because of this rails app doesn't start with syntax error. Also i'm getting errors like ActionView::Template::Error (incompatible character encodings: ASCII-8BIT and UTF-8)

    using mail for ruby I am getting this message: mail.rb:22:in `encode': "\xC7" from ASCII-8BIT to UTF-8 (Encoding::UndefinedConversionError) from mail.rb:22:in `<main>' If I remove encode I get a message ruby /var/lib/gems/1.9.1/gems/bson-1.7.0/lib/bson/bson_ruby.rb:63:in `rescue in to_utf8_binary': String not valid utf-8: "<div dir=\"ltr\"><div class=\"gmail_quote\">l<br><br><br><div dir=\"ltr\"><div class=\"gmail_quote\"><br><br><br><div dir=\"ltr\"><div class=\"gmail_quote\"><br><br><br><div dir=\"ltr\"><div dir=\"rtl\">\xC7\xE1\xE4\xD5 \xC8\xC7\xE1\xE1\xDB\xC9 \xC7\xE1\xDA\xD1\xC8\xED\xC9</div></div>\r\n</div><br></div>\r\n</div><br></div>\r\n</div><br></div>" (BSON::InvalidStringEncoding) This is my code: require 'mail' require 'mongo' connection = Mongo::Connection.new db = connection.db("DB") db = Mongo::Connection.new.db("DB") newsCollection = db["news"] Mail.defaults do retriever_method :pop3, :address => "pop.gmail.com", :port => 995, :user_name => 'my_username', :password => '*****', :enable_ssl => true end emails = Mail.last #Checks if email is multipart and decods accordingly.

Replacing UTF-8 with ASCII-8BIT gives a similar error. I get the same result when using plain_part for plain email messages. I am handling emails from one specific source so I can put html_part with confidence it's not causing the error. To make it extra weird Subject in Arabic is rendered perfectly. What encoding should I use?

  • Tuning MySQL to consume less memory

    - by Alex
    I have a VM which has 2GB Ram, (full specs) And I am setting up a site which has one table in particular with over a million records. There's little or no usage of this particular database (perhaps once or twice a day) but simply running mysql grinds the whole server to a halt. I've looked through the top results but nothing is really denting the CPU however the memory seems to be the issue. The site isnt even live of taking requests yet. the memory situation looks like this: # free -m total used free shared buffers cached Mem: 2006 1880 126 0 3 53 -/+ buffers/cache: 1823 183 Swap: 2047 345 1702 Are there any good pointers to tune mysql to stop hogging the system memory? Thanks very much EDIT: (requested by 8bit): http://tny.cz/b41a0b12

  • Java bitshift strangeness

    Java has 2 bitshift operators for right shifts: >> shifts right, and is dependant on the sign bit for the sign of the result >>> shifts right and shifts a zero into leftmost bits http://java.sun.com/docs/books/tutorial/java/nutsandbolts/op3.html This seems fairly simple, so can anyone explain to me why this code, when given a value of -128 for bar, produces a value of -2 for foo: byte foo = (byte)((bar & ((byte)-64)) >>> 6); What this is meant to do is take an 8bit byte, mask of the leftmost 2 bits, and shift them into the rightmost 2 bits. Ie: initial = 0b10000000 (-128) -64 = 0b11000000 initial & -64 = 0b10000000 0b10000000 >>> 6 = 0b00000010 The result actually is -2, which is 0b11111110 Ie. 1s rather than zeros are shifted into left positions

  • How to browse a Matrix returned by the OpenCV2.0 Canny() function ?

    - by user290613
    Hi all, I've been browsing the web to get an answer but no way to put my hand on it. I call the Canny function that fills me a matrix Canny(src, dst, 220, 299, 3 ); the dst variable is now a Matrix that is according to me of type CV_8UC1, 8bit, 1channel. Now I would like to browse this matrix according to rows and columns, so there was a trick that I've seen on stackoverflow dst.at<uchar*>(3, 5) In my case it crashes. (Assertion Failed, unknown function, cxmat.hpp line 450) My matrix information are myMatrix.width() = 181 myMatrix.height() = 65 One more thing, when I do std::cout << dst.depth() << std::endl; It always retrieves me 0 and not 8 (which I guess Im suppose to get) Thank you very much for all who will reply,
