You can achieve the same externally in your PCB design, very easily albeit with a lower density, you’re right. On processors such as the Atmel AVR that power is in the single microamp region – the clock doesn’t need to be running.
Hi, thanks for the reply! Since it is regulated and is what the rest of the components run off, I was going to use the 3. I will fix that tonight. The main use is for channel switching I say main becuase when the amp is in manual mode, the buttons control other things but this mod is for channel indicators It is connected via a TRS plug basic 3-connductor stereo plug S1 switch is for changing the bank Red or Green LED and the CH is for the different channels the amp can store 4 channels per each of the two banks Changes the voltage of the signal line S 3.

ON part of the switch is not used but has Vo I could split the datashet having 2 isolated switches and connect per original idea. If you find the switch bounce affects the circuit performance, you can add a capacitor of nF 0. Dec 8, 1. There’s a good chance that quiescent current added to the system by an extra logic IC would be greater than the current consumed by the MCU waking up and executing a handful of instructions.
Basically just have a short signal to trigger the reset instead of a continuous high signal as would be from the LED output.

Always have one LED on. Dec 15, 9. Dec 8, 45 0.
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 thought the IC could handle 10mA. To conserve bandwidth, I only dstasheet 1 bit in a synchronous “sub-frame” channel to send the analog signal as a digital FM signal of 0 to 1kHz.

I have toyed briefly with the possibility to use the Enable line, but was not sure if it would have datassheet the latched states. Sign up using Facebook.
Got some parts in today to test and a new solderless breadboard I have wanted to get one for years. Once you correct that, can you go through exactly what the circuit is supposed to do? Dec 15, EDIT — to clarify a few points in the design: Actually, the second one is pretty much the same as tkng’s. I see a small error from moving parts around. Backup question maybe deserving its own question: Below is part of the circuit with the switches.
I remember seeing info in the CD datasheet on the CD? I would disagree, but I may be missing the picture here.

LED selection indicators controlled by multiple switches Reply to Thread. A couple of other options for “radio buttons”. I always believed it was easier to search from something when you know the technical term. You can test it using a breadboard. Dec 16, As far as possible I cd4034 to keep it digital and without any high frequency line anywhere or, better said, well confined in their own “realm”: Thanks for all your help so far sorry for the long winded thesis below Finally got more specifics on the circuit I’m modding.
I think I will have to stick with that option for now.
