HT datasheet, Pinout ,application circuits HT — Remote Control Encoder
Results 1 to 6 of 6. Join Date Mar Posts I have project for remote control. I want to use ht holtek transmitter in side to remote control. By the way, I want to use pic16fa for receiver side. But I dont know anything related to ht Dataeheet think you used this IC before.
Pls help me for this. Thank you for your interest.
As far as example code it would only be a couple of lines long. Basically set AD0 to AD8 pins to the data you want to send either high, low or floating and then pull datasheeet TE pin low to start sending, pull TE pin high to stop.
That’s it as far as I can see. Write something, try it out, if you need help come back and post the code and I’m sure someone will be able to help. I can use pbp, and I have already software for different project.
But I will use holtek first time and I dont know what can I do?
HT – Product Details – Holtek
How can I translete it and use it. I’m sorry I misunderstood the question there. I think you would need a matching decoder chip, however looking at the HOLTEK website there doesn’t seem to exist such a thing – like there is with the HT12 series for example.
If you’re trying to receive data without a corresponding decoder chip then you’re going to have to look at dahasheet timing diagram at page 4 in the datasheet and then try to write code that syncs the receiver with the pilot period of the transmision and then deciphers the data according to the timings for “0”, “1” and “open”.
Hopefully someone else has more hands on experience with these than I have and could lend you hand.
Again, sorry for missunderstanding the original question! You are trying to help for me.
Maybe I couldn’t tell it. I seen code like to this, but it is ASM. I dont know ASM more. This makes the decoding much more difficult using PIC instead of a dedicated chip. To decode this in software, I think it is necessary to use interrupts on PortB.
Then with the timers of the PIC you can measure the width of every pulse by starting and stoping the timer for every pulse that triggers the interrupt pin on PortB. It would be necessary to use a second ddatasheet also to have a timeout, if the incoming series of pulse is noise and dump the collected data so far. Every data packet is 72 clock long.

For 20KHz clock this is dtasheet ms. So if the data packet AD0-AD8 is longer than say 4ms, software should consider it as noise.
Now that I check each pulse, it seems that for 20KHz clock, each pulse is 50usec width. It may not be possible to decode in basic and assembly might be the way to go.
