Re: Mute GPIO

Thanks for the kind words, I have put years into it. Most likely when the next beta is finished, I will make another video with the hood taken off. I have had go extra steps to reach for the professional performance that makes it transparent. It's been quite a journey. There are a few important piec...

Re: Mute GPIO

Thanks again Phil for the reply, No rush at all. The project is in working order as it is, but these changes will bring it to a professional level of operation. The changes should drop right in using even the present connections and parts while enabling a few additional potential changes in the futu...

Re: Mute GPIO

Thanks again Phil

Is it possible to hook me up with someone you know that could put all this together for me for hire?
Somebody perhaps that knows about the audio subsystems and overlays?

Re: Mute GPIO

Thanks Phil for the reply, For clarification, I use shairport-sync, which has a built in buffer for the audio of 2 seconds in a normal config. This 2 seconds actually gives me all the time I need to complete all the sequencing that my system requires. If I select a track or other type of file with a...

Re: Mute GPIO

Hello again... I have had great successes using the above methods for some time and have lately decided to try to go a step further in the use and functionality of the DAC driver or overlay..

Re: Overlay file system setup for Buster?

What are your results?

You can possibly link to /boot and leave that read write while changing the mode in raspi-config.

In this case, only one reboot necessary for changing modes, and can link other non-critical powerup/static configurations to the /boot partition..

Honestly this new feature helped my projects well.
I just happened to stumble across this and it eliminated a few parts and added functionality.

Thanks Yes I've looked into a variety of things that could do it, dual transistors, gates etc... I'm doing my best to use as few and as few different components as I can in the project. One issue is that two gpio are controlling relays, so need a bit more power than a gate can provide, or would add ...

Re: New "gpio" config.txt command announcement

I'm certainly challenged when it comes to many things, and I'm not even sure if it isn't a reality yet, but I think it would be cool to have a feature that could reverse the high/low output of a gpio pin, independent of some program that is controlling it already. I use a DAC that makes a pin high w...

I have tried a few different settings and the only way that I have gotten a low is to set dtoverlay=gpio-poweroff,gpiopin=16,active_low=0 My desired flow is to have the GPIO16 be set as a high triggered input for dtove...

Hello Question for the engineers here...

The function would be somet...

Re: Raspberry Pi3 project using GPIO and LEDs

Additionally,

I like the when_held method over the when_pressed in that it eliminates the possibility of getting on the wrong side (opposite functioning) of an edge based method.
