Do some basic check that your gsm is working and receiving the sms properly.Test and checked with single msg send command from PC and controller.Lcd is working fine try display simple text and initialization all working good. Then you can switch over the receive the massage part.Sorry I didn't go through the code.I will update soon on your code
What is your display size? Is it taking more current than MAX7219 can handle? In your code, you should rearrange it using a state variable like below. right now there are many logic that can go wrong in the loop. And the display update you should put a timer interrupt like 100ms to update a global counter variable to (...)
Hi, (almost) every FFT is possible. The question is the number of samples and what time it may use for calculating. Please specify the FFT parameters. In many cases a display update rate of 3 per second is no problem. Klaus
Hi, I can´t help with the PIC.. Is the numbering of the ADC channels correct? --> When you select channel6, is this referring to correct port pin? but some hints, if you don´t mind. * a capacitor next to the ADC input pins helps to make readings more stable * a display update every 300ms is enough, so i recommend to use a 300ms dely in your mai
HI ALL, I have this plotter .... I have few questions ... Do I need to install internal hard drive for this plotter? Where I can get firmware update for Flash SIMM card? Printer has ALL LEDs are blinking and on display I can see "A" Any ideas? Thank you for your help, guys.
Initialization 1. set timer 0 as counter by using T0CKI clock input 2. set the corresponding bit in TRISx register which connects to T0CKI external clock to 1. 3. set an interrupt for timer0 in interrupt routine. Normal operation 1. when interrupt occurs add one to a static or global variable 2. update it to a LCD display or on UART or reset timer
Your circuit is fine. I will check the code and update. I think this is causing the problem. I guess it should loop from i = 0 to i < 16. The lcdbuf1 and lcdbuf2 doesn't contain anything and hence 1st coloum of LCD will be always blank but the 16th column will be filled. If you have Proteus file then Zip and post it here. [syntax
Hello seniors.. I have succesfully configure my ds12c887 rtc to be read and to display everything on the jhd162a 16*2 lcd using 16f877a... Problem.. When i m tryng to update the date and time its getting hard to do that.. Last time i tried to turn on the swuarewave pulse for 2hz but it ws not working...but then i repeated the call for that su

I'm working on arduino based project, that actually can perform 3 features: 1. Virtual Touch Screen, for remote control purposes big screen TV, projectors, public display, or for interactive games 2. 3D Ultrasonic Radar, small range - 3 m for now, but real time with update rate 50 fps; 3. Precise distance measurements , down do 12 micromete
Hey,thank you Sir for the response I want to display on seven segment and I would like to be able to set the time,to update the system if possible.I am using PCF8583 not DSO1307. Thank you!!
Hi, Give us some more information: What is your disired max. Rpm to disply? What is your desired resolution of rpm? How often do you like to update your display? Hint: Usually you wait a known fixed time and count the pulses. Then calculate rpm by: counts/time With low rpm one waits for a rising edge of sensor signal and measures the time
What would be the benefit of this, when update rates above 100Hz can't be followed by the eye? "The higher the better" may feel good to say, but is certainly untrue by some point.
A 2x16 character display can be updated in less than 10 ms, using either 4- or 8-bit mode (if coded appropriately). For a periodical refresh, you'll probably want to use a timer or a flag set in a timer interrupt.
Please bear with me. I've to toggle a pin every 125 milliseconds and every minute I've to update the eeprom with a value after comparing with the previous value. For measuring time I'm using Timer 0 and it's ISR. Every minute I've to display the eeprom value in an LCD. My PROBLEM is that for the 1 second period the toggling is working fine, but dur

Can you save it as a template? Or for other designs open it and update it to a changed schematic?
Heya.. got a project in lpg controller for some school kid. Its like this, the kid has to turn off a gas burner using a Uc after a time period. I have done some coding using the basic stuffs.. but iam stuck at "update" of the 7 segment display. i.e in the main function : int main(void) { init(); for(sec=0;sec<=1;sec++) { _d
Hi; As recommended instead of clearing screen with a background color just update the new image. As you insert fix color background human eye can catch it, unless you drive the screen around 100/120Hz. Even around those higher frequencies, inserting blank picture reduces screen luminance. That means a darker screen perception. Goodluck
HI, I used Altium designer 10. the only change made ​​was to add a header 9 and when I have to transfer the schematic in pcb that is not read. saying the 'error mentioned above. thanks
Have you tried to update your graphics driver and do you press 3 on the keyboard, I had an old laptop and still was able to view 3d graphics. Try this go to prefernces then PCB editor, Then display and make sure the direct x if possible is ticked use flyover zoom in directx is ticked you can aslo test your direct x from there wizpic

Friends, Can I use STM32F103VCT6 with uCOSII2.91 and uCGUI3.90A ? Because from datasheet I saw the flash memory of STM32F103VCT6 is 256Kb and the result of compiling uCOSII2.91 and uCGUI3.90A is 689K I'm using Keil4 for compiling uCOSII and uCGUI. If I want to update or costumize the display on LCD, The step that I must take :
Hi all, I would like to generate line graphs on a web page. I want to measure analog signals using FPGA and display the signal on a web page. The web page should be dynamic such that it will be updated after a short period like i second. Does any one know how I can code the web page> I have checked on the net but from the sites I have visted so fa
Hi Foot. I have done similar project to this in the past and found that perhaps using an array of characters is not the best approach, I used the maximum size available to me in the PIC which was a long long (32bits I think) which made life easier for if I wanted to dynamically update the display, although I can see that you are just trying to d
I let you know for information update the problem fixed by replacing panel.
I am a newbie on FPGA, I have used the manual from Xilinx to create my own intellectual property, but I need to Read and display on a terminal the current shown LED pattern as binary pattern and unsigned integer number e.g current LED display:00001101 number is 13. update this mode permanently.
I am using AT89C51 as my micro-controller; 74HC154 as my decoder connected to port 1 of the controller; AT24c16B as my EEPROM; MAX232 as my level converter connected to serial port; 12MHz as my crystal oscillator; and the dotmatrix display unit are connected to port 2. I am having a problem with the program I wrote for the micro controller. The
Interface speed does not determine needed drawing speed. You have to consider size of data set (number of samples simultaneously displayed) and display update frequency. 57600 is pretty low speed still. Personally I would prefer LabWindows than LabView - base editions have same price but LabWindows has deployment capability. There are (...)
I don't know what mghz are but if you are talking about the maximum rate at which you can update a display and people can still read it, I think that is 4 times a second. Keith
Count from 0-9. After 9, make the segment displaying 9 equal to 0 and add a 1 to the segment left of it. update displays at say 50 mSec to suppress flickering. Remember, human eye can not distinguish flickering if the frequency is greater than 10 Hz. And lastly, the code you are requesting is not very difficult to try. Better try it (...)
hi all, Could you tell me how to export S-parameter from layout design in Momentum (or EMDS), ADS 2008 update 2, because I would like to use extracted S-parameters to simulate in HSPICE? For example, I made a onchip transformer in EMDS, ADS 2008 and now I want to put it in another schematic in Virtuoso and I intend to use its S-parameter to s
Please Help I'm working on a scrolling LED display using 5X7 dotmatrix. I'm inplementing on PIC18F series and looking for a means of updating without wires. wireless or infrared using RS232 port. Please I need help.
Hi, If you can increase the pulse output from the encoder, you can correspndingly reduce the period of accumulation of pulses and thus increase the speed update rate without affecting the accuracy. Otherwise if you can sacrifice accuracy, for a given encoder you can speed up the update rate marginally. But these methods are limited in scope in
Hi, If you have already implemented a PWM scheme to control the display brightness depending on the ambient light, it should work either way, that is the brightness should fall automatically when the ambient light reduces, where is the problem? As regards display update, it can be updated as fast as half a micro (...)
Hi To make a component from your layout structure: In the layout window select Momentum->Component->Create/update There will be a lot of options. When done, you just go to the "display Component Library List"(Button with the Books on the shelves:-)) No ADS is not very easy to use, when you want to make really precise and odd shapes. Maybe
Colleagues, Could you recommend a 2D chart control for my application that can work with VB6? I need to plot an EEG signal on the screen in real time. The update rate of the chart will be on the order of 200ms to 1000ms, and I want to display 1000 points. Ideally, the whole chart would scroll to the left as new values are added on the right.
You should use timer based interrupt code to update or "scan" your display hardware. The interrupt code can also easily detect and debounce your input switches and set flags for MAIN that indicate "new" switch presses. Mike
In the ISR I would just decrement a counter every time I get an interrupt. When that counter reaches zero I would read the timer and display (update) the time.
Assuming that you are using 16*2 charector LCD using Hitach lcd driver built in. Initialise LCD using the command sequence described in datatsheet. then send 01 as command -lcd cleared and cursor on position 1 of line1 If you enabled auto incriment position during initialisation it is easy to update. when you want to update some part of
Hi, Sumit007: IE3D 9.0 is old and the CURVIEW is also very old. Please update to the IE3D 11.5 release. The current visualization is integrated into the layout editor MGRID on IE3D 11.5. On MGRID 11.5/CURVIEW, you can display vector current. However, you may need to change some setting. For example, you shouild adjust the sizes of the vectors
In my opinion doesn?t matter how many rows you are using for the display, when actually the most important part of the transceiver is the RF circuit. If you want to update the radio to 2006 technology probably you have to start with that part.
i THINK u can do that by booting from CDs and update but i didnt try it b4
You should not see glitches in the text display. You should see a continuous stream of "0" values with no "1" values. Each time a "clk" transition occurs, "a=0" immediately drives "a" low. "a<=1" schedules a go-high event to be executed after all active events complete. Since "$display(a)" is an active event, "a<=1" will update "a" after
If you are referring to an lcd display, there is no short-cut. You would have to implement the scrolling/shifting the tedious way. You'll need a buffer. And you need to update the entire display whenever you do scrolling, and most of it when you do shifting.
There will be other people who will argue about this, but if you read the feedback from Pr0tel users you will find that the greatest number of those who have display problems are those who use ATI graphics cards. It is, indeed, most likely that your graphics card drivers are at fault. If you are going to use ATI, update the graphics card bios an
On my RH7.2 linux box, ic5 Linux version has serious display problem when using 24 bits color. It occupies too much CPU resources when operating the wave window or layout window. Anybody encounted the same problem? I'm just wondering that if update Xfree86 to Version 4 would help or not?
