The data can use almost any protocol desired, including RS with or without manchester coding. No pot for contrast. Once the wire connection will work, i may suspect 2 other things. The dataslicer uses a comparator as I explain at http: IF I pressed pad1,pad2 and so on. Maybe Joe has bifocals like me. Maybe you screw the OSC signal with your probe. If you do not believe in MAGICConsider how currency has value simply by printing it, and is then traded for real assets.
I will suggest you to test it without the RF modules for dstasheet. Actually I want to send a character using my RF module. What kind of comparator circuit are you planning? If your data is riding on the noise at 1. I didn’t read the according datasheet to see if it affect anything though. I also recommend sending 3 or more copies of each packet, including the wide sync pulse.

Join Date Sep Location himak, canada Posts 6, Join Date Dec Posts 1, OK, i’ll start a new thread later about how using the internal comparators. Results rx3310q to 40 of Also, what’s the signal look like at 1. Hello Steve, Since I still receive noise. But It’s fine to me. Adding another will not help. Seems to be the one you’re using right? Join Date Mar Posts The time now is There’s a load of noise indeed I never used those ICs Your best bet is to use the techniques I’ve recommended repeatedly.
Is there any chance for the receiver to get the sending data clearly without noise If I connect the data pin to LM ?

But It’s not work even I Connect the transmitter and receiver pin directly. Joe, seems you missed the underlined section There’s no problem, only learning opportunities. I try to change the baud rate but nothing happens. Rx33100a PIC are you using? Here is the code and the schematic of my hardware. Without any spec of your module, it’s a bit hard.

You can also try to add more Synk character at the begining of your transmission. For your Information, I put 1M resistor between these 2 pins.
I just add 10k pull up resistor at Rx data pin and 10uF at Vcc. Nowi don’t know the RF receiver you have, but it’s possible that it’s output is an open-collector type. Now I’m moving foward to send a data from my keypad.
I think maybe the problem is from the antenna. In this case, the only output from the receiver is digital so the noise pulses will have the same amplitude as the data dattasheet the duration of the noise pulses are likely to be nearly the same as the bit period. I’ll also suggest you to follow Dave’s post http: See pics in POST 1.
There’s a long long long way in between, i think you could try the Inverted mode first and then slow the baudrate, say bauds.
Join Date Aug Location Look, behind you. I would suggest you to add a 10K pull-up resistor between Vcc and RA. Pause 50 ‘ Debounce getkeyu: At least it’s work. Thanks for all the advice Now my Rx module datasheeet fine in a short distance around feet. Furthermore, if you look at the block diagram in the datasheet from the HiMark RXA chip, you will see the comparator in the output circuit.
Adding another comparator might be useful for educational purposes but is of little practical value IMO. Originally Posted by Joe S. Then adjust until the black boxes go away. Join Date Jul Posts 2, Try those with direct connection.
