ASA to ALL im eorking on led matrix display consists of 16X16 led matrix can any body tel me what will the appropriate timmer1 relode value for this..... and why if you explain so i clear my concpts for scanning your input will be highly apprictaed thx
hai, cud u provide me with ur project details i am also thinking about d same concept but know confused how to start pls help!!!!!!!!!!!!!!!!!!! Added after 5 minutes: i am also trying to impliment 100x100 led msg display using dot matrix. as i know very little with my knowledge i went upto 16x16
Anyone please I need some help/idea on how to implement this pic/microcontroller project: I need to implement a pic project ( possibly 16F84) that controlles 8 set of led that can turn ON/OFF and any of this led can, according to program parameter, display 7 color. In another words I need to controll a 8X7 (...)
Hi, Recently I got a gaming machine display board from ebay, It has 6 5x7 matrix ,32 bar graph led's and 4 MM5450 controllers. Is it possible to use these controllers with AVR or pic to make a moving display..? I am attaching the circuit and the picture of the pcb.. Thanks Surej
Drive the Display directly from the pic outputs with no limiting resistors and no BJT or FET. pic FET outputs are source self-limiting at 25ma. Connect the 8 Sink lines directly to pic outputs also. For such a simple single led matrix circuit.... throw all the other components away! I have proven (...)
I've got a 8x5 led matrix, with common anodes and cathodes lined up. Now, of course, I can command it from a uc (like a big pic, 16f877) but it's not too bright, because the pic can't really source too much current, and it has to be multiplexed. So, I want to build a power level for it, with transistors. Of course, we can (...)
hello i am working at a full color led panel. Currently i am building an 8x8 dot matrix, each pixel being formed from 4 leds (2R1G1B). How can i use PWM to control the led array, what kind of pic or IC should i use?
Hello everybody I want to make one project that support to my Master programme. That project is pic (16F628A) accepts the every character from usb and display on the led matrix array .The character display is at least 10 character and more how to accept the character . Can anyone help me and Thanks.
I am new person to this,any one know the circuit diagram,coding for led Moving message (permanent)from pic 16F877.pls help me
Here is an example of 4x4 keypad + led display based on a pic microcontroller: All what you need to modify is instead of displaying time display number/character of a key pressed .. Another example is based on 8051 microcontroller:
Hello boys, Does anyone used the max6953 to drive 4 5x7 led matrix displays? I would be very grateful for some sample code to address the max6953 from a pic(16f84A). I have difficulties understanding the protocol from the datasheets. Thanks Nikos Geronikolos
Hi, Search Elektroda forum: ................
i try to make a rotating text on eight 7x7 led matrix displays with two max6952 IC's how can i connect a microcontroller to this chip ( PINS DOUT, CLK, CS, and DIN) Link to max6952 Please give me a schematic with software
Where to find a nice development board for pic 16F8XX (schematics + pcb) with LCD module 4 x 4 matrix keyboard 8 led RS232 interface IIC Serial EEPROM interface bootloader supported regard
check Dallas/Maxim. There is a chip from led Dot matrix Controller. You will get easy in programmning
