Hi everyone, I’m trying to porting some of previous weatherstation samples I’ve built on others Arduino (mkrwifi1010, nano33iot, arduino R4 wifi) to the new Arduino Q. I’m doing this usind Arduino IDE 2.3.6 I’ve learnt the hard way that there is no serial communication possible for debugging purp…

Sorry, but I will not look at code where every other line is empty. Good luck.

Hi, You could use a visual help with STM user led 1 and 2. You also could use Serial (RX pin 0 and TX pin 1) to debug you application with an RS232 to USB adaptator and this is the only way to detect a zephyr OS problem when loading your application as it use Serial to print error messages. What …

Thanks @bborredon for your swing answer. I think that my problem is not with reading DHT Sensor, but is related on how to view / debug what Arduino Q is reading. May I ask you which system / IDE are you using, since Serial.print, that is the ovious/straighforward choice for communicating with the…

I use 2.3.6 IDE on Debian 13.1. As I write, you need to use an RS232 to USB adaptator connected to STM connector pin RX (0) and TX (1) (ground to ground, RX to TX and TX to RX but not VCC) and a terminal emulator (I use putty both on Windows and Linux) to connect to the serial device (COMXX on Win…

[image] apagliari: Serial.print, that is the ovious/straighforward choice for communicating with the board apparently is NOT working with WINDOWS systems yet together with Arduino Q. The problem you are referring to is with using the Monitor object to communicate via the UNO Q board's USB CDC…

[image] apagliari: I’m doing this usind Arduino IDE 2.3.6 I’ve learnt the hard way that there is no serial communication possible for debugging There is also now a fix for a problem that caused the serial output from the USB interface of the UNO Q (as produced by the Monitor object in the sk…

Good morning. I have the same issue of Andrea, it happens there is no way to get DHT11 sensor to work with Arduino Uno Q. I'm using the Monitor object to debug and tried with the Adafruit library and the test script provided from them. Nothing is coming out, only nan values. Same code works ok on E…

I found a solution to the problem. I was originally using the TinyDHT library, but it did not work properly with the Arduino Q (UNO R4 WiFi). After switching to a different library called DHTesp, everything worked correctly. Below is my working code using the DHTesp library. #include <DHTesp.h> #i…

[image] apagliari: BME280,..) sensor with ArduinoQ? BME280 works well with UNO Q IDE 2.3.7 in Here .

[image] momo1223: DHTesp.h Thank you Momo for your suggestion. I tried to properly install the library you pointed out within ArduinoAppLab but I couldn’t find it: [image] I used the same approach that worked out while adding other libraries. Am I perhaps missing something?
