KICAD files corrupted in download I downloaded them again and they worked. I have another question...see additional post. Thanks!

Wiring it all up Question about how you wired it all up. Is the attached diagram correct? Also, what are the center wires on the matrices for?

What version of KiCad are you using? I tried versions 5.1.9 and 6.0 Neither can open your schematic...

A little advise from anyone is appreciated. I'm looking at the Teensy 4.0 Scrolling LED Sign project located here: https://www.pjrc.com/scrolling-led-sign/ 1. I'm curious what the "300R" objects are in the circuit board layout (page 7 of 9 in FuntionDescriptionLEDMatrix_V1_00.pdf, located...

I recently tried to download serial_install.exe and Windows Defender reported it is infected with PWS: Win32/Lineage.gen!C.dam

I finally figured this out. The callbackEcho sketch now compiles and works. Earlier, I was trying an nRF8001 support library posted by Tato123 https://github.com/tato123/nrf8001_arm_support. (I think this was before you started working on it.) Later, I had tried an nRF8001 library from...

Paul, I have been using an nRF8001 on Atmel for a while now without problems. I need to move the project to ARM and have been unable to get this library to compile. I started with Arduino 1.0.5-r2 and Teensyduino 1.18 and have tried every version since. I am now using Arduino 1.6.7 and...

I am learning about USB and I would appreciate any guidance on this project. I would like to make a USB protocol analyzer: When the PC (USB host) transmits on cable pin 4 (TXD), it is read on Teensy pin 0 (RX1) and is then transmitted on Teensy pin 10 (TX2) and received on pin 5 (RXD) of the...

Teensy [3.1] input voltage range Paul, The K20 Sub-Family Reference Manual (K20P64M72SF1RM Rev. 1.1, Dec 2012) states "The USB Voltage Regulator module is a LDO linear voltage regulator to provide 3.3V power from an input power supply varying from 2.7 V to 5.5 V." Why do you mention...

Paul, How about part numbers or source for the plastic base and standoffs? Care to share the Gerbers for your custom board? Do you think OSH Park would manufacture?

Check out noInterrupts() and interrupts() functions.

According to this https://www.pjrc.com/teensy/td_libs_EEPROM.html, "On Teensy 3.0, the EEPROM data is erased when you upload a new program. " This does not appear to happen on Teensy 3.1. Is this due to Teensy loader changes, etc?

Thanks Paul. I guess I will shelf the WIZ812 adapter and try the WIZ820io (or try a Teensy 2.0.)

Researching further, the diagram on the Ethernet page (https://www.pjrc.com/teensy/td_libs_Ethernet.html) shows the following parts: •1: LD1117 regulator •1: 10uF capacitor •2: 0.1 uF capacitors •1: 1K resistor But the WIZ812 Adaptor parts list contains these parts: •1: MCP1825 3.3 Volt...

I am just learning about Teensy, and with 35 years experience in the field, I understand it is sometimes aggravating to assist a newbie catching up with the "tribal knowledge" for a product. (Especially a hardware engineer explaining software or vice-versa.) I recently purchased a Teensy 3.1...

Paul, How about posting the schematics for the adapter boards? Specifically, I am interested in the WIZ812 and WIZ820 adapters. I am using the Teensy 3.1 (a GREAT little board) for prototyping, but eventually will want to make a custom PCB... Regards, Derek

DUH!!! That was it. :o I remember reading that now, but translating the tutorial pin-outs from Teensy 2.0 to 3.1 must have been too much for me! Now that I think about it, I also remember seeing something funny with the pot in Tutorial 3 (obviously wasn't thinking enough about it then...)...

I recently purchased a Teensy 3.1 and the tutorial kit. I have been working thru all the tutorials and have run into a roadblock on Tutorial 4 (https://www.pjrc.com/teensy/tutorial4.html) When I run the sketch in the last Tutorial 4 listing (modified to print out code), here is the printout I...
