On Key press you append the key value to an array and terminate it with null character and use this string to display data on LCD. You also use a counter to index array elements. On Key press (except back space) keydata = Key; keydata = '\0'; displayOnLCD(keydata); //If backspace is (...)
does anything display on the LCD? have you checked the baudrate by connecting the SIM300 to a PC? by using polled UART receive you are probably loosing data while you transmit the AT commands and you will get receive overrun on the UART it is recommended to interrupt drive the UART receiver with received charcaters placed in a ring buffer
If I define a custom character that uses the lowest (8th) pixel row also, this row is never displayed, although the HD44780 datasheet says this: The 8th line is the cursor position and its display is formed by a logical OR with the cursor. Maintain the 8th line data, corresponding to the cursor display (...)
I need a Mega 2560 shield for 3.2" TFT display with touch screen and also for XBee. My system collects data received through XBee and displays it on TFT. I have seen shields for XBee and TFT but cannot use both at the same time.
You can send values from microcontroller through Sim900 to a server. Main tasks of the microcontroller are as follows: 1) Configuration of the SIM900 module for TCP/IP Client mode, 2) SIM900 control via AT commands for data transfer, 3) Updating the Microcontroller display if any, when the corresponding command is received from the Server.
both approaches are possible 1. build a single application in C++ which talks to the device via a serial port and has a GUI front end built using wxWidgets, GTK+, etc 2. run a C++ based web server with talks to the device via the serial port. A PHP web front end contacts the server to display data received and control the device. This should b
I assume you will be receiving the keypad data from the PIC18 via serial port the project is possible in Matlab, i.e. it can read data from a serial port and build GUIs alternativly you could use Java, C++, C#, VB.Net, etc all of
Are you able to see the Hsync, Vsync on the CRO (You can check these signals by connecting a prob on the display's Hsync, Vsync ports). also check the clock. If the Hsync and Vsync are able to see... then try to find whether the RGB data are zero or not.. if the RGB data are zero then also you can see black screen.
... and bar code readers usually produce serial ASCII output so all you need to do is display the characters. It would be up to you to look-up the character string in a table and display data accordingly. The type of code is normally worked out by the scanner itself and can be requested from it if necessary. Brian.
I am using one way communication for sending data to display from microcontroller. In this case as the output of 75176 is always enabled, are the bias resistors necessary? Secondly, the cable length will no exceed more than 5mtrs, so are the termination resistors necessary? Let me explain my project. It consists of two devices one controller
Search for "128x128 LCD" and you will find hundreds of suppliers. You will have to search their data sheets to find an exact match for the cable though, I think most of that size are made for mobile phones and customized for a particular model even if the display itself is the same. Brian.
hai there, Thanks for your reply..i manage to debug the code and it ran nicely on the board..but the problem i facing now is..i cannot display/import the digital data which i obtained after i convert the analog signal inside my pc. i tried to use system generator but its not working as well cause i need to purchase the toolbox for the simulink..
1) Those square blocks indicate that you are not sending correct data to the LCD (or are not sending it correctly). Unless you are INTENDING to display blocks. 2) It sounds like something failed. 3) You have to be aware of static or overvoltage
I am trying to display an image on a monitor/projector using the DVI port of the Xilinx XUPV5LX110T. From the user manual, I saw that DVI port has 4 pins for 4 bits of R G B each. With that it has 6 other pin outs. I can generate the RGB data. Can some one please help me with the other 6 pins on how to control them?
Hi All, I'm working on a project for one of my classes in which I get to implement a design of my choosing, and I am attempting to interface with the on-board Cellular RAM of the Nexys-3 Spartan 6 and do asynchronous and synchronous reads and display the data from the memory (which I programmed using the Adept interface) to the 4 SSD's by displ
