RF development board

[Bruce]

Hi Folks,

We have a new RF receiver board for the linx Technologies long-range LR series receiver modules.

It's available as a bare PCB, PCB with pre-soldered LR receiver, and full kits with PBP code examples
for decoding Holtek HT12E & HT640 encoders, and code for creating your own 8-pin encoder/decoder
ICs.

hello sir,

I am having a txd-433-kh2 and rxd-433-kh2 pair

when used to turn on Contact-er of 3-phase motor, the output of receiver is oscillating

this is because the interference of motor to the holtek decoder,

if you please share the code of HT640 decoding it would be of great help and I would try to decode the code on microcontroller,

I referred your last post on same topic but i was unable to interpret the code written there to convert it to my atmega32 microcontroller in C program, if you have C program, please share it

thanks

The Linx KH2 transmitter uses the Holtek HT640 encoder, and I have posted code to decode this particular IC here http://www.picbasic.co.uk/forum/showthread.php?t=6581

Of course, since this is a forum for MicroEngineering Labs compilers, the code is for the PBP compiler.

If you need this translated to an 8051 core device, in C, I can do that, but there will be a charge for the conversion work.
