Pic Encoder Decoder

max 232 is mainly to convert voltage level from ttl to -9vdc / +9vdc and also curren amp to prevent damage for pic ic used hope it helps ziad

i want to use pic 676 as PT2272-m4 (remote cotrol decoder). i just want to decode the code comes from PT2262 RF remote encoder. Can any body help me? Thanks in advance

Hii thank you for reply. Can anybody knows how to interface ST 3659 RC 5 decoder to pic 16F887 and HT 12E encoder interfaces to pic 12F629 based IR transmitter ??? Can aybody replied asap much appriciated ???

What kind of data do you want to send?If it is 1 to 4 bits of data you can use HT12E Ic connected to your pic microcontroller and the connecting RF module to the the encoder IC.Use Haltech decoder IC at the receiver side.When you are using haltech encoder and decoder you will et at the receiver what exactly (...)

There is my code for encoder on pic16 (hi-tech picc) thats on a russian, but you can use google translate.

i am looking to build a device that among other things will control a mp3 chip. in the past i have built these and used the winbond isd2590 chips ,and it works great. however i want to up the sound quality. it took me months to write the code to control them and the other devices because im not that good at assembly langauge and cant even begine to

For high speed decoding, you preferably use a pic with built-in quadrature decoder. Your code is decoding the overrun condition CUR ^ PRE == INV, but ignoring it. The code seems to miss up/down decoding. It should be implemented even for unidirectional operation to achieve correct counting with bouncing or or unclear level input signals. You

hello frnds, i want to send data using a IR from pic microcontroller.. which encoder/decoder is suitable for this application? if im using ht12E/HT12A/ht12D/ HT640/HT648.. what should be the r osc value( oscillator) .. can any one post a working circuit diagram to transmit data.. Thanks in advance....

Dear Sir, Iam attempting to transmit data using RF. For that i have to interface pic16f877a with HT640 encoder. Similarly at reception i have to connect with HT648 decoder. Pls provide Circuit for these two sir. Kindly help . :cry:

Hi... I want to send a sine wave to PC using wireless communication.. im using RF serial communication with pic.... but im getting very noise in communication... to avoid noise i used HT640 encoder n Ht648L decoder... Nw im getting nose free data but im missing sm datas n takes more time to receive.. hw can i avoide these problem ... is (...)

It is very simple to interface TX RX modules with pic just connect the DATA pin of TX module to TX pin of pic and RX pin in the case of RX mudule. And use the same UART program. You can simplify the program or directly control devices by using decoder/encoder ICs linke HT2D/12E. Any doubts post it........

Is there any way that I won't use microcontroller in doing this project? Yes, there is. You can use a DTMF encoder at the transmitter side and, a DTMF decoder at the receiver side. Now, you have not only the 9 freqiencies you need but also 6 extra frequencies for future improvements. Take a look at the

i need pic based fsk modem encoder and decoder projects. any links plz?

Dear all, Can anyone help me with this small project? I am planning to design a small infrared beacon with a pic microcontroller as the encoder/decoder which works with a IR transceiver, TFDU4100. I want this beacon to be able to work with the PDA by transmitting information from the beacon to the PDA. As I use a pic (...)

Hi Search CC {Circuit cellar} site thay use to have DAS algorithm for pic micro controller You can adapt it to work on arm All the best Bobi

HI, How many tasks your pic have to change? If they are few, you can try a simple communcation implementing something like a encoder decoder. If you nned to change 2 tasks you can set an output 0 or 1 for tasks and read the PIN in second pic.If you need 4 tasks you can use 2 pins, 3 pins for 8 tasks and so on... You (...)

Hi All, I am looking for POCSAG decoder AND encoder based on pic processors. I need to know any more about POCSAG protocol. How I can control 10-15 receivers. Any software ? Any ideas ? Thanks, Pioneer_007

Hi, i need to replace a Holtek HT12D and HT12E with a pic 16f676, do you know source code for this ? Thanks Totue

I think that FX614 by CML is the easily mode for make a modem, with a pic you can make an encoder, but if you want a decoder you must make an frontend circuit with operational for amplifier and square the level (FX614 or 604 decode at 50mVpp), for filtering the band. At the end is more complicate and expensive than dedicated chip

Hi, where i can find a valid and simple RDS decoder and encoder pic based project ? 8O
