Thank you very much Paul, I wouldn’t have thought of that solution. 24 MHz and even 150 MHz work, but not 396 MHz. This reduction in speed does not seem to affect the rest of the project, which involves MIDI communication via the USB and USB...

Before you upload to Teensy, try setting Tools > CPU Speed to 24 MHz. Looking quickly at the library code, the send() function at line 62 and the latch() function at line 115 appear to be written for Arduino Uno at 16 MHz. There's no delay in...

Thank you both. Inserting a delay or running an LED_Bar command on a rising edge doesn’t solve the problem. My UNO R3 clone seems to be compatible with the library, unlike the Teensy. It’s a real shame because this gadget is exactly what I...
