I found the problem! It's actually the function "void yield(void) {}" defined in this HX711 library. After I commented out all lines containing it, now Teensy compiles/uploads and runs normally. Although I don't quite understand what yield() do in arduino/teensy programming environment. Any...

Below is the HX711 library (cpp file). I'm suspicious about several places that may cause trouble with a Teensy 3.6: 1. Arduino.h 2. #if ARDUINO_VERSION <= 106 // "yield" is not implemented as noop in older Arduino Core releases, so let's define it. // See also...

There was no LED at all. So it's probably something wrong in the library code? Maybe the library is specifically incompatible with Teensy 3.6 since I can get Teensy 3.2 works with it.

Thanks for the help. However, my problem is that I cannot even open the serial monitor. Once I upload the code (the moment of "Done uploading"), the serial COM port disappeard/gone/died. If I try to open serial monitor, I got message "No serial port, please select with Tools > Port"...

Thanks for elaborating the mechanism behind HX711 code! Since it's a relatively straightforward setup, I'm pretty the wiring is correct. Here attached some pictures on my hardware setup. I hope they are clear enough. Teensy HX711 3.3V-----------------VCC GND-----------------GND Pin...

I tried adding the line and compile using "FAST with LTO". However, the serial was still killed before I could even open the serial monitor.

Hi everyone, I'm using a Teensy 3.6 with a project involving load cell. I hooked up Teensy with HX711 load cell amplifier from Sparkfun. Here is the webpage: https://learn.sparkfun.com/tutorials/load-cell-amplifier-hx711-breakout-hookup-guide My hardware setup is (the default setup suggested...
