22 sie 2024 · With the Nano Every, the sketch works fine using the IDE Serial Monitor. It does not work with my VB app: the led does not turn on or off, the read from the serial port only returns one character and that one has nothing to do with what is in the sketch code.
13 wrz 2024 · I am using an Arduino Nano Every with a Nano Qwiic shield and two PCF8575 GPIO expanders to control 40 LEDs, receive commands over Serial1 from a custom Atmega328p board, and read an I2C flow meter. Everything works besides being able to properly receive commands over Serial1.
Select the serial device of the board from the Tools | Serial Port menu. This is likely to be COM3 or higher (COM1 is usually reserved for hardware serial ports). To find out, you can disconnect your board and re-open the menu; the entry that disappears should be the Arduino board. Reconnect the board and select that serial port. Upload the program
11 gru 2021 · Most Arduinos (and the Nano Every is one of them) will reset when the serial connection is reopened (You close it by closing the processing sketch and open it again with the Serial Monitor). Variables are stored in RAM, which gets wiped and reinitialized after a reset or power loss.
30 kwi 2021 · I try to communicate with the Arduino Nano Every through the serial usb port. This works fine when using the Arduino Serial Monitor. But if I use a different monitor/device, the arduino nano every will not respond.
Try setting the baud rate to 9600 in the Serial Monitor. You need a working serial port to open the Serial Monitor. Or go to >File >Preferences> and edit the preferences.txt (must close Arduino IDE before editing) "serial.debug_rate=9600".
