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: Fona problem- no signal

To piggyback on this, I am having the same problem. I am getting no RSSI and cannot tether to a network (the network status goes from unreachable to nothing). The network LED is blinking but not solid. I took the ting sim card ...

Re: USB / DC / Solar Lithium Ion/Polymer charger - v2

I hope I can piggyback a request onto this thread... I have the charger wired up with solar panel / battery and connected to a Feather M0 WIFi , but I have an issue. If the battery gets too low and causes low-voltage shutoff, the ...

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: impossible "contact"

Re: ESP8266 Feather & MP3 Reference Design

Is the flash chip accessible for the piggyback connection? It seems like it's either a different format than SSOIC or internal to the module. Nope. It's under the can. Is there a better way to add RAM, and will it require significant changes ...

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 ...

Re: 5V fan connection on RPi 3?

Mike, Do they make a connection that can "piggyback" onto the GPIO header. I want to be able to have the plug on 40 pin cable still connected along with the fan. Thanks for your reply.

Re: adafruit-vs1053

... and don't fit into your existing structure too well. The simplest approach is probably to scan the break-beams in an interrupt routine. You can piggyback onto the main timer interrupt (as is done in some of the GPS example code). Read the sensors with digitalRead (not debounceRead!), and put ...
