Any chance the price has been reduced from €70 a piece? I'd definitely be interested in them.

I think it's much more likely to be heated related than a built up electrical charge. I think you've got a short somewhere. It heats up and eventually browns out, dropping the connection. Try disconnecting everything from the Teensy and powering up via USB. See if the connection drops out. If...

Try using a digitalRead instead of analog. Faster and, likely, more precise.

SD cards pull a lot more current than you might think. Most 9V alkaline batteries have now switched to flat cell construction (6LF22) which are only good for low load applications - voltage drop is significant with even moderate current draw. Look for a 9V alkaline that says "6LR61" - these use...

First off, the max baud rate isn't 115200 on the Nextion. It's 921600 and I use this baud rate reliably in a production product. So, start with "baud=921600". Next, regarding the minimum timer delay of 50ms of the Nextion - that's just the lowest value accepted by the Nextion Editor. You can...

I have an existing Teensy 3.2 based project that has been regularly updated over the past couple years to add an ever increasing list of features/capabilities. The constant stream of updates have steadily increased the size of the firmware image and has now reached a point where it's consuming...

I'm going to assume you've already worked out the analog circuitry for handing your piezo signals (amplification, impedance) and that you're simply working on capturing and "replaying" incoming signals to help on the firmware processing side. First, use pedvide's enhanced ADC library. This will...

I believe you need to be looking for a list of PID's, preferably make/model specific. These serve to identify the different values and sensor readings accessible thru the CANBUS. Some of these are fairly standard/universal for the most common sensors, like VSS, O2's, ECT, IAT, etc. But I'm...

I suspect the market for 3.X will still be strong for both new designs and existing/legacy products. The 3.2/3.5 are particularly well suited to certain applications (analog heavy, 5V tolerance, etc) that can make migrating to the 4.X platform extremely difficult. My application, for example...

From my experience you CAN damage other on-board components when applying excess voltage to a Teensy GPIO when the voltage is large enough (~9-10V+), the circuit path to the pin does not have an inline resistor to limit current and the other PCB components are supplied 3.3V thru the Teensy...

This is what I use on 3.2 void loop() { Serial.println("USB Status: "); while(1) { if(USB_Status()==0) { Serial.println(" NONE"); } if(USB_Status()==1) { Serial.println(" USB"); } if(USB_Status()==2) { Serial.println(" USB + SERIAL"); }...

Below is basically the code that I've used for some time. Works on Serial1/Serial2/Serial3 without issues. Automatically sets the max baud rate which makes for quick uploads. If you're using the Nextion Uploader then it will see the connected Teensy as a Nextion device and automatically find...

Not sure if this helps but your defines don't match your code. You have: #define XSERIAL Serial1 #define YESERIAL Serial2 But your following code refers to YSERIAL #include "Wire.h" #define XSERIAL Serial1 #define YESERIAL Serial2 void setup() { Serial.begin(115200)...
