i want to make a wireless rf trigger for my camera with 16channel..! yeah i know for that i have to use encoders and decoder ic..so that i could use address line as channel using dip switch..! but i want to know is that i have open two transmitter circuit that are not chinese they have use jst single 14pin ic for 16channel and 8pin ic for 4channel. so can anybody tell me what ic's it could be because its niether of ht12d or ht12e so anybody knows about it please share asap.! i am attaching picx what i have mention..! please tell me is it possible to use channel with using any enoder or insted of that any microcontroller which can have 16channel rf transmission..?

while searching about all dis i found this ic but i dont think this is the one beacuse its vdd n grnd pins are different or is it any possibility that 8 pin ic can b any controller let say pic12f629..but if it is controller how could we add different channels using same rfmodule 433mhz without using encoder..???

It might be a custom designed IC maybe an ASIC? If you can make wireless work without encoder/decoder and only using PIC controller then there is a chance you can add a software address byte to it, to identify which controller is sending data.

sir please elaborate the idea in more detail..?? and how its possible using dip swtch/

they set encoders with address settable through DIP switches. I am not sure what IC they are using. Its just that they might not be transmitting any special data, just the address to identify which device to be triggered. But this is just a guess coz we have no idea about that IC.

ok i am trying to implement by making my own protocol but m getting so much noise at receiver..!
can you plz share noise filter circuit so that after receiving data i can remove noise and get proper digital data..??

are you using encoder/decoder or directly connecting RF modules?
