Hello team, I am a beginner learning to use verilog coding to measure power on Xilinx-FPGA. Custom-built circuit. IDE-- Xilinx ISE 14.7 I want to check if my AES encryption and decryption design works on an FPGA (with the highest switching activity so as to compare the estimated and measured values). The code below is just the TOP module.
i want to interface p10 single colour led module 16x32 with pic micro. any sample code kindly help i cannot get the schematic for p10 if any one have kindly send. how much io will p10 led module need with pic
If the led module is designed for 5V, neither the led backlight nor the contrast adjustment will work.
Dear Friends This Arduino program is done for 10 led Matrix modules. where i am getting error. For 8 led matrices it worked properly But when the 9th module is added it is displaying the first module character when the 10th module is added it is displaying 2nd modules (...)

Pins on one side of the matrix display connect to anodes and the pins on another side connect to cathodes. Have you connected anodes and cathodes properly ? Doesn't apply here. "P10" led module is a ready made module with serial mux interface. Unfortunately it's not clearly mentioned in the initial post.
I can't give you the code because as far as I'm aware, you will be the first person to use it and I'm not prepared to spend hours writing it for you. I will help you to write your own program though. You need to make decisions: What PWM rate do you want to use? How much current does the led need? TSOP devices will decode any IR protocol, are you
hi, am planing to develop a 5x7 dual color matrix led display. am using a single module and am used this for a status indication not for scrolling. my requirements are, condition 1: all green led on condition 2: all red led on condition 3: all red and green led on simultaneously. ie yellow color. i (...)
Hello! Im working with a Simcom GSM SIM900 module and having a problem: My software works fine for hours, sometime days, and suddenly loses network registration for no apparent reason. I know because I lose communication and the network led blinks fast. It will only work again if I turn the power off and on again. Any ideas where to look
Chinese ... but only 0.74 US$ and free shipping:
this is two to data available in rx pin of esp8266, blue led means data read by esp8266, my suggestion is 1. try proper baud rate 2. check for connection problem any pullups 3. try to update the firmware(if success your device is good need to check anyone of the above and if failed device gone) add: esp8266 doesn't have voltage protection so mor
Hi. I found at my workplace an evaluation board based on GSM module SIM508 EVB V1.01, manufactured by SimCom What seems to be the problem: I have inserted a valid SIM card; soon after I activate GSM (by pressing Z1 button ) the GSM_NET led start blinking and then stops after 10-15 seconds. During this seconds ,I receive string "Call Ready
Hi, I am dsPIC30F5011 controller and i want clarification about key scan in TM1638 led hardware connections like this Controller(Master) TM1638(Slave) -------------------------------------------------- CLK CLK Slave Select Strobe DI
Hi all. I am currently working on a project which involves an mp3 module and i would like to get an led to react (in light intensity level) to the amplitude of the signal it generates. i am using a transistor to drive the led with the base connected to one of the mp3 modules speaker outputs which is amplified(enough to power (...)
Hello Everyone! I have absolutely no experience in this, and had no idea where to begin; Google hasnt really made things clear(er). I am looking for a readymade module (or, if not, designs, or ideas to make one) that would soft start an existing led lamp. I'm talking about controlling an led bulb, the kind that directly plugs into the (...)
When i power up for the module, i see all led is turned on, and when i use realterm to test it, the data appears continiously (like the following images), i don't know why, please help me, thanks so much120742120743
Hello, I uploaded thermistor firmware to XRF module and now it's responds just to "+++" command over serial monitor, also heartbeat led is always on. From my researches I think XRF is in bootloader mode, but I'm still not sure. I tried several firmware versions with two diferent modules, all is the same. To upload firmware I used XRF (...)
Hi dear frends, help me to led on/off with sms massage through picbasic pro.
Hello guys! I started to learn programming PICs a couple of days ago using Myke Predko's "123 Microcontroller Experiments for the Evil Genius" and Proteus 8. I reached an experiment where the author shows how to program a 2 digit 7 segment led, so I decided to do something more challenging for me: to read the value of ADRESH and display it on the
I'm trying to simulate a Gsm controlled led Display Device using Proteus. I have no idea on how to go about this.
