try using a buffer/unbuffer whose size is an even multiple of the size of the encoder/decoder
The receiver should work OK but the transmitter circuit is suspect. First point: make sure the transmitted data rate and receiver data rate are the same. Second point, the transmitter data inputs have internal pull-up resistors but your external transistors also pull the inputs to VCC, you need to pull the inputs low,
Hi. Cannot find information or equivalent. Can you help please ? It is a 20 pin dip, the 3.58MHz resonator is across pins 6, 7. Power minus to pin 10, plus to pin 20. Markings are: ESS 9009 ---> could be date ES3016-5 ---> Seems to be the part number --->
Hi I disgned 128b/132b encoder and decoder block in verilog code but my data width is 8 bit and my encoder' s input in 128 bit so how can I communicate my data bus with encoder?how can this encoder get 16 8 bit symbol?
Hey new to the forum and i need help with a project i have de2 boards and i need to have one board encode a message and the other board decode it and display it on a the 7 seg leds we have the encode/decode code but not sure how to get them to talk
Hi I want to design 128b/132b encoder and decoder.I got the verilog codes for 64b/66b encoding system but I dont know how should I use it for 128b/132b? Do you have the verilog code for 128b/132b?If no, please help me to write the codes
Hai Everybody, I want to do Digital communication lab experiment (SOURCE encoder AND decoder) using Multisim. So anybody please help me for which type of encoder and decoder can we use. Thanking You. With Regards, Sindhuri.
Parallel port has >50kB/s bandwidth easily. Your design requires a refresh rate spec and allowed latency, supply power source and LED Vf @If specs. If 0.5ms is allowed then refresh rate is 2kHz then parallel rate is 25kHz x8bit / Serial encoder/decoder would require 100 x 2kHz rate. If you need to latch the LED state, a serial clock and data po
Hi ;-) Can you help me with 64b/66b encoding?Do you have verilog code for this encoder and decoder ?or Do you know its architecture at gate level?
hello guys. I just begin with Proteus and i like it so mutch, but i have a big problem. In fact, there is no HT12E encoder and HT12D decoder inside. So i want to import HT12E and HT12D librairies but i dont know where to find it. Please help me! Thanks, Hugues.
cheap ASK modules won't give you good result unless you code them properly. Manchester coding or other suitable coding schemes. I strongly recommend you to use HT12E/HT12D encoder decoder pair ICs for acceptable result. Otherwise, you better use nRF24L01+ or similar standard modules as Easyrider83 suggested.
Why did you mention a microphone and a speaker? A microphone will not press a pushbutton switch on the encoder and the decoder does not have a power audio amplifier. If you set the encoder's oscillator to be an audio frequency then there will simply be a buzz if the decoder has an audio amplifier and speaker connected. I (...)
There's no such thing as "execution time" in logic design. We have logic propagation delay, clock speed of synchronous logic and possibly pipeline delays. In a synchronous 8b/10b decoder or encoder, the clock speed is usually equal to the symbol rate. Timing analysis assures that the implementation can keep up with the clock rate.
we are having 8 address bits. so we got only 2^8 combination. so we can able to design only 512 pairs. if we want to design more than 512 pairs, what we will do. Lets say that you want to design 1024 pairs of encoder and decoder both.Here you will be having 10 bits(1024=2^10).What I think could be possible(Could be wrong too,might n
i am doing project on turbo codes so if any one could help me for sending me the verilog code
This is in a generic register file generation and I have this code, when I synthesize, im getting a priority encode decoder. Is there any way I can avoid priority encoder/decoder for for loop? Else is there any way I can have a case statement which is scalable (dont know how many case expressions will be there beforehand) 1 for( i
AS you mentioned you are getting valid data from decoder.. But you are not getting for LED... kindly post the schematic of your design... iam checking for data transfer through ht12e and ht12d via using direct connecting dout and din pins...the problem is that ..iam giving input at data pins of encoder but the led's at de
Hi, I am working on a project that involves interfacing of camera with microcontroller cc2540. The raw video is to be encoded into H.264 format and transmitted over bluetooth low energy interface. I am looking for C code for H.264 encoder and decoder. Where can I find C code for H.264? Thanks.
Name some Cheap IR encoder and decoder except holtek and Princeton technology
my project block diag: keypad(input)=>pic16f877a=>max232=>DTMF encoder=>RF 433 ASK Tx => RF 433 ASK Rx=>DTMF decoder=>max232=>pic16f877a=>relays the data is being correctly transmitted and received using max232. so in cross questioning if i asked why i'm using max232 is then what will be the answer?? plz help me
