Beaglebone Black audio?

... mistaken this doesn't sound like a great option (unless we use the PRU) because we need precise timing between samples. Our second thought was to piggyback on top of the BBB's ability to play audio. Is there a nice way to get audio signals off of the BBB without using the USB port? Or is this ...

Re: feather huzzah esp8266 battery charger

... safely), but it won't hurt the Feather. Having unsoldered many 0805 resistors from tight spaces in my time, my advice is not to try.. just piggyback a second resistor on top of the existing one so the parallel resistance is close to 2k. The nearest standard value (E12 scale) that would ...

Re: Feather GPS + M0, cant start LOCUS logging

... way to do this without using the timer interrupt. Can't use the UART receive interrupt from the GPS, because the UART driver is using that. Can't piggyback on the system timer the way it's done in the AVR processors, either. I'm going to have to think about this. I think I'm going to have to set ...

Re: DC Motor + Stepper FeatherWing

Lets draw this in a simpler fashion. The topology of 2 bridges wired in parallel is like this:

Re: Pi Zero W w/Camera Kit camera not working

... Edit - after thumbing through the forums, I see that folks generally start their own thread for the their own issues. I thought it made sense to piggyback on this one since I had the exact same issues, but I will start my own now.

Deadman's switch using momentary button

... This is to control power to a power tool. The button would normally interrupt power, but when depressed, it would allow current to flow through a piggyback plug (like http://a.co/edN271m -- ignore the foot pedal part, which I would probably cut off). Problem is, I'm unfortunately pretty much a ...

Re: SOLAR PANEL / Li-Ion Battery / Charger Arduino Raspberry

... You could use two solar panels and chargers to power the cell phone and RasPi separately (an Arduino uses 200mA at most, so is small enough to piggyback on either of the other device supplies), but we don't have anything that would work as a single panel/charger solution.

Re: How many MPR121 can I connect to a Pi B+ v1.2?

No need to piggyback the multiplexers. You would just use one, connected to a Pi, to provide up to 8 output channels. Each device on a specific channel needs a unique address. However, you can have duplicate addresses across channels ...

Re: ESP8266 Feather & MP3 Reference Design

ESP8266 Feather & MP3 Reference Design

... uses an I2S DAC (like the awesome amplifier in the Adafruit catalog ) as well as some extra RAM for a buffer. The reference design recommends piggybacking the RAM on the back of the SPI flash, and attaching the CS pin to GPIO0. That leads me to two questions regarding the Adafruit Feather ...
