I am working on a wireless project. I read about the HT12E/D and purchased a few. The issue I am having is that the decoder seems to be latching (as was confirmed in other posts). So what is happening for me, that is detrimental to my needs is that I get a logic low on my output (pin 10) regardless of an active link between E and D (pin 17 to pin 14 respectively). This occurs when direct-wired together.
What I am looking for is an active “output” when there is an active link between Encoder and Decoder through the transmitter and receiver. I am using the Encoder/Decoder to weed out any other 433MHz signals floating around.
Am I missing something in the wiring of these chips? There are VERY vague ideas on what resistor to use between pins 15 and 16 on each chip.
Is there a better E/D combo that I can use that is “non-latching”? Working voltage is 6-12VDC. I am using a simple 433MHz transmitter and receiver from Amazon.
Thanks in advance.
