Hello,
I have an rf receiver module. It has a signal regeneration chip on it, with one data line per remote control button (rf signals not the issue).
The receiver module has four outputs, D0-D3 + VT (valid transmission). When I press a button on the remote the VT pin goes high until i release the button, but the corresponding data pin just blinks (high 100ms each 500ms) from VT goes high (button press) until it goes low (button release). I want the data pin to act like the VT pin, constant high signal while button is pressed.
I've attached timing diagram of how it is today. I considered a one-shot 555 timer to trigger on data pulse and re-trigger for each pulse. But then I could have a transmission delay of nearly half a second which is not good when I'm using the remote to fine tune a lid with a motor on the output. So I need to take advantage of the VT pin somehow.
Only using two data pins, each will trigger a relay (motor will spin fw/bw). So if I could latch the relay on data pulse, then release it when VT goes low, would be perfect. I've tried to come up with a solution, and I know what kind of chip I want, but don't know what it's called.
The chip I need has 2 or more data inputs and outputs. When one input is pulsed the corresponding output is latched. The chip will be powered by VT pin, so the latch is released upon button release.
Thanks for reading my post
