Hi I have readymade working electronic product. I am applying reverse engineering on it. The WiFi module is connected to microcontroller via UART( RX & TX). The android app sends command to wifi and microcontroller works as per the command. I have attached a USB to TTL cable on RX and TX also command ground as well of WiFi module. The cable is c
2- and 3 -segment 7 segment LCD displays are usually non-multiplexed. You get the segment data by XORing segment´and backplane signals.
Dear experts, I am having problem of plotting integer signed data say temperature in VGA display. I have VGA controller where there is a RAM which stores data from the sensor of temp. Inside the controller I manipulated x and y axis and send it to VGA where it displays the axis. Now my problem is when I get the (...)
Hi everyone i'm on a project about the communcation 1 Wire i have a DS1922 that i have to run. i did a script for a " Search Rom " commande to identify the ID and display it on the LCD. it worked fine. now i'm doing a MATCH ROM with the ID that i found, i'm just looking for a simple code to for example to mesure the temperature every 30 sec
Hi all, I am working on a project using PIC18f4520 and mikroc. Here there are two displays which are connected to a computer. One of two displays is a master and another one is slave. i am working on a slave display. So whenever master display gets character 'A' sent by a computer via serial communication, it sends all the (...)

I heard first time GPS module with SPI, Anyways Try going step by step first connect only GPS module and then GSM. And display data received on LCD or any terminal for easy debugging.
Hi, What code do you need? Gprs modules often communicate via UART, but it could be any other interface, too. Code for sending and receiving data with a UART? Or do you need to know the GPRS commands? How do you want to process the GPRS data? Storing in memory, showing on a display, transmitting to a PC? Please give detailed (...)
I am having MATLAB SIMULNK Model. I want to interface it with proteus for reading data using PIC and display in LCD.Whether its possible to interface like that???
We have a need for an embedded system/project that can accept a data and clock serial TTL level signal at up to 12 megabits/second and make the data available to ingest and examine by the processor. Selected parameters will be extracted from the stream and output to a display computer. We are flexible on that media and can use Ethernet or (...)

What I want is to simulate circuit when WH=13 & LH=80, next curve when WH=14 & LH=84, etc.Use "data Access Component" with Discrete MDIF Format data File. Here sweep index using one controler. See the followings.
It's hard to tell from the post exactly what you are looking for, or what your current program is doing. A guess would be: Convert binary data from six switches to 2 decimal digits. Something like the code below, using integer arithmetic, could be used: input = PORTC; // read the switches input = input & 0x3f; // mask upper
Suggest to read an ICL7106 (=AME7106) datasheet and learn how a (non-mux) LCD display works. Segment and BP pins are toggled between V+ and internal digital ground (at about V+ - 6V). To recover the segment data, the pin state must be xor-ed with BP. 125471
Hello! I have never played with the Sitara boards, but an SPI screen is really easy to use. If you find a way to use GPIO (try to blink a LED for example) and a SPI, then you just wire the SPI to the LCD, the GPIOs to the proper places (usually chip select, data/Command, Reset) and you're on the right way. Usually you can find the initialization p
I want to read data from L&T EM101+. I have optical probe to communicate with it. The protocol used to read data from the meter is IEC1107(IEC60117/IEC65026). From some documents and websites, I have got certain message sequence to communicate with a IEC 1107 supported meter. I tried to communicate with it using those messages. But i didn't get
Hi, I need to display something through VGA at 30 fps. I am afraid we can just send data from 60fps as I am unable to find any details such as back and front porch, syncing times when sending 30fps.. Has someone an example displaying something through VGA at 30fps ?? thanks for your help !
You don't need to tie the unused data lines on the LCD low, it is best to leave them unconnected as the LCD has quite strong pull up resistors on them.
read data (pixels) check against the ranges for the bins, increment the bin count (another memory) that has a range that matches the pixel, display the resulting counts on the monitor. Of course this is probably what you were supposed to "design" (i.e. figure out on your own).
Hello, I bought GPS receiver VK16E and now i want to interface with At89c2051. This is the first time i am working with GPS and i have poor knowledge on micro C.

Hello, I'm looking for a device that has an LCD display (2x16 will do) to display data, but i want to send the data through bluetooth. does this product exist ? Thank you in advance
Pl, any body can reply for this, I want to send 8bit data into different port pin of 8051 , for example a=0x06; this is to be displayed D0 on P2.7 and balance to be displayed on P3.2 to P3.7 .
A single flip-flop can be made to divide an incoming pulse train by 2. A 'data' flip-flop is the customary type for this purpose. Connect one output to the D terminal. If you have a bunch of transistors, it should be possible to homebrew a flip-flop.
Hi, I want to display images on a LCD by using a ov6620 sensor. for this I use a FPGA that receives data from ov6620 and send them to LCD . I can manipulate OV6620?s registers and think all recommended points in its data sheet are considered but the image is not correct . in fact i have a dismal image that means one of the stages of my try (...)
Maybe I missed it, but where do you initialize the LCD? LCDs have an initialization procedure, with very specific timings, where you set such things as cursor style, 4-bit or 8-bit data input, etc. Without this sequence, the LCD will do nothing. r.b.
hi, My LCD manual states: Note: Perform the Function at the head of the program before executing all instructions From this point the Function set instructions cannot be executed unless the Interface data length is changed. E
You have to display data in two different modes and use Timer interrupts. If you want I will write a program for you. Which MCU you want to use? PIC, AVR, 8051 ? What crystal frequency will you use ? - - - Updated - - - You have to use a button to toggle the display mode. If button status is 0 then adc value
The original MDIF description is very general/unspecific and MDIF can be a container for all different sorts of tabular data. It seems that GMDIF has a more specific use of fields/names. Have you checked the Agilent documentation on this?
Hi All, I have been asked to work on a new project. It is like this: RF433 MHz Transmitter - 3 Nos. RF433 MHz Receiver - 1 No. Any transmiter can send data to the receiver and receiver has to to read it. Request can from any transmitter, the receiver has to sequentially receive the data and display it on LCD/LEDs. I am aware (...)
for data pins use multiple entities and it will appear as U1A, U1B, U1C, if power lines donot appear then go to properties, click on hidden pins, assign the pins by naming the power lines infront of VCC and GND. This will connect them in schematic as well as PCB layout
