    Firmata: Use "Input" on boot.

    I'm using a Teensy 3.5 and a bunch of hook clips to peek on my wired security system in my home. I have to use analog because the voltage used (~1.6v) doesn't exactly register as a digital "high" for...

    Contacts for underside pads?

    I have a couple projects in the future that may involve using pads at the bottom of the Teensy 3.6 board, but I don't want to have the contacts soldered as that would be messy and require extra...

    OK, so what I actually have is a USB Zigbee dongle that normally goes into a PC or a Raspberry Pi. It uses a JN5169 zigbee module and goes from UART to USB within the dongle.

    Use Teensy 3.6 USB for serial.

    The embedded serial port on arduino and teensy is also the uart0 and can be used for debugging. So to use USB, you need only to use functions like Serial.println() and Serial.Available().

    Is this...

    SD card open second file.

    I was going to put this on the Arduino forum, but seeing as it is using the Teensy SD library, I figured I would try here first. This is on a Teensy 3.6

    How would DigitalRead not work? That would be the important one. All I need to do is read the data.

    Uh oh. I already built a board around it.

    Is there a way to bit-bang the pins to be used in a similar fashion? I imagine not, since i would need a negative voltage source.

    Update:

    Teensy 3.5: How is USB1 accessed?

    I'm trying to communicate with a USB dongle using the the USB1 pins (A25, A26). This was chosen so that the USB dongle can communicate separately from the integrated microUSB port. I've been having...

    OK, I deleted the existing SD folder altogether and placed in yours. It all seems to work just fine now. Thanks!
