Do you already have an account? Can’t yet wrap my head around applying a D or JK that way. Thanks for your input! While not the ideal for the approach datashert simple, cheap and reliable circuit, with only the MCU as “critical complexity”I believe that your comment may deserve an answer by itself for posterity.

To conserve bandwidth, I only needed 1 bit in a synchronous “sub-frame” channel to send the analog signal dtasheet a digital FM signal of 0 to 1kHz. The way I plan to implement it the MCU could well stay sleeping all the day, until the measurements are taken and the SR reset. You can use RS flip flop or D flip flop to make a circuit for the requirement. You might way to use the common enable in the CD to implement the solution you’re looking for.


I’ll do a little testing to measure current draw and should be ready for the perfboard.

While this is not a huge problem to solve and still dwtasheet my requirements, the resulting design is not as clear as it would be with a single Reset and the density is lower, requiring me to use more ICs.

Dec 10, 5. However is practically impossible to find good supply of it and even a datasheet. So moving those diodes and disconnecting the D and barQ will make it pretty much the same as Ken’s diagram if I’m not mistaken aside from the output transistors. Led light controlled by dmx Posted by charles01 in forum: You can test it using a breadboard.

Basically just have a short signal to trigger the reset instead of a continuous high signal as would be from the LED output.

Is the enable line capable of dataseet “resetting” the latches? If you find the switch bounce affects the circuit performance, you can add a dataheet of nF 0. You guys are the experts here! MCU, comms module and voltage regulation sections. With all these invisible radio frequencies flying through the air, we should know a little bit about what exactly they are!

I’m still trying to get used to those truth tables. Many thanks to the both of you for your help!


Just wanted to update on this project. Dec 19, 2, Thanks again for your cdd4043 A couple of other options for “radio buttons”.

ON part of the switch is not used but has Vo I could split the poles having 2 isolated switches and connect per original idea.

Dataxheet on this board while searching the internet with no luck. On top of that, when I will get into power-optimization for the MCU I may end up having to choose between keeping the interrupts alive or saving power. I want to keep it flexible, both capability and power-usage wise and this requires balance. I have toyed briefly with the possibility to use the Enable line, but was not sure if it would have cleared the datashee states.

I might stick with the because it uses only one IC chip. Dec 17, But you all know how it works Looks like an SR is my only choice cd043, but my brain is just a drop of the ocean. I would prefer a non-toggle action.
