I would like to get into programming in c++ with computer boards. I know there are some educational boards out there that you can hook up to the computer and write simple programs to make lights come on and do simple stuff like that. I was hoping that someone on here could give me some good resources on where i might get these kinds of b...
I have an embedded project that I am working on, and I am currently coding the character LCD driver. At the moment, the LCD driver only supports "dumb" writing. For example, let's say line 1 has some text on it, and I make a call to the function that writes to the line. The function will simply seek to the beginning of the line and wri...
I've recently built a Tweet A Watt (http://www.ladyada.net/make/tweetawatt/) wireless power monitor, which uses XBee for data transfer. I'm attempting to get the Tweet A Watt data into Processing for use in creating some visual energy feedback prototypes. Using the XBee API Library for Processing (http://www.faludi.com/code/xbee-api-li...
I am trying to generate publication-quality circuit diagrams within a LaTeX document. What options are available? ...
Any luck using the Arduino Blackwidow or the Yellowjacket. I can't find much information online about them in terms of reviews. I would like to connect to a wireless router, send small POST requests pertaining to resistances that have been read and receive responses in JSON format that would be instructions on switches that should be f...
I want to start FPGA programming. I don't have any knowledge at all about how FPGAs work and such. I would like to get a development board, not too expensive, but it should have at least 40 I/O pins. Anything up to $300 is OK. I decided that I want to program in Verilog. I am not sure about the following: How will my compiled 'program...
i need the derivations that how these formulae comes Vavg=Vpeak/pi for half wave rectifier Vavg=2Vpeak/pi for full wave ...
This question is more about electronics than programming, but there's no StackExchange site for that yet (at least I was unable to find it). The idea is to open an electret microphone and glue a flat surface (for instance, a piece of glass) on it, and use an ADC to detect when someone presses it with the finger. The ADC will be attached...
Hello, I did not find a place holder for asking questions related to Digital design - Frontend / Backend(Physical) on stackexchange. So i proposed one there on area51. So for time being asking my question here - 1]I am looking for a book on Physical Design/Backend design for beginners. I am basically a software developer,having overvie...
It appears that some electronics have programmed within them what's called an "alarm subsystem". What exactly is this subsystem? what does it tie to? what does it do? Is it known by any other name? If I were to program one, in general what would be the pseudo logic of it? Please don't mind going heavy on the details as I'm really new to ...
I have to obtain dual tones from DTMF 6847 chip.Which pins are to be shorted to obtain different sets of frequencies so that I can see them on the oscilloscope? Please help. ...
Hi , I just learnt of TopoR routing software. It routes PCB traces without grids, with curves and arcs for reduced trace length and vias. http://www.toporouter.com/ But its not a complete PCB routing solution , they have examples on how to use it with DipTrace. At work we all use and are comfortable with EagleCad . Has anybody us...
Is there a performance impact, especially with regard to battery performance, if we switch from the default black theme of android to white or another colour? ...
I'm look at writing some code to simulate some electronics and need to model some transistors. Does anyone know of a resource that has models for several kinds? (Or at least several kinds with high gate impedances and fairly linear analog performance as that's what I'm going to need.) Systems of equations and tables of values for stock ...
I want to Make Simple a Quiz Buzzer Circuit With LED. e.g. I need LED instead of Buzzer. I don't need any reset Switch. I want to maximize the Use of Logic Gates in this Circuit. and Obviously no Capacitors are Allowed.and obviously no microcontroller. I am trying to do this for 2 days. But Cannot Make it Out. I think The Basic Idea sh...
Hi all, This will be my first try at USB intefacing ! May I know how to transfer the data from pins : 11-15 of KT3170 IC to USB ? Data sheet : http://www.datasheetcatalog.org/datasheet/SamsungElectronic/mXuusvq.pdf I guess I will need to configure a Microprocessor for making the OS uderstand what profile of device is this , In that Case...

I am attempting to connect and control a device which only accepts RS-485 input. I wish to communicate to this device via my existing UC3A1512. Does anyone have any existing source code or examples that may help me to create this interface? I need a method of outputting date via RS-485 format. I do not need to establish round trip co...
