Using the MKR IOT Carrier + Web Editor. Trying out the tutorials. Code is copied and pasted and then downloadad. Works fine, will show me temp and humidity on display and print to serial (COM3)/monitor. When I make small changes to the code and download it again it doesn't work, no temp/hum on display and no print out to serial/monitor. Tried to shut off fire wall but no change. What helps is disconnecting the USB and then connecting and downloading again.
Any ideás?
It is in the 9th line or possible the second last line. I cannot see what you can so you need to post an annotated schematic of how you have wired it, be sure to show all connections. Hint: I do not read frizzies or word problems. I do not have your parts so post a link to each of the hardware items that gives technical details. Also post both pieces of code following the forum guidelines and note the changes.
Thank you!
I use the Arduino Explore IoT kit: https://www.arduino.cc/education/explore-iot-kit
The MKR IoT Carrier is mounted on top of the The Arduino MKR WiFi 1010 board. The Arduino 1010 stays connected with the computer via USB.
The code below will work the first time I upload it. It will render nice printouts in the Arduino Editor/Monitor.
/*
Explore IoT - Activity 01
Read values from a temperature and humidity sensor
and print it in Serial Monitor and on a colored display.
This example uses the IoT carrier and the MKR WiFi 1010.

#include <Arduino_MKRIoTCarrier.h>
MKRIoTCarrier carrier;
float temperature = 0;
float humidity = 0;
void setup() {
Serial.begin(9600);
//Wait to open the Serial monitor to start the program and see details on errors
//Set if it has the Enclosure mounted
CARRIER_CASE = false;
//Initialize the IoTSK carrier and output any errors in the serial monitor
carrier.begin();
}
void loop() {
// read the sensor values
temperature = carrier.Env.readTemperature();
humidity = carrier.Env.readHumidity();
//Update touch buttons
carrier.Buttons.update();
// print each of the sensor values
Serial.print("Temperatur = ");
Serial.print(temperature);
Serial.println(" °C");
Serial.print("Fuktighet = ");
Serial.print(humidity);
Serial.println(" %");
//function to print out values
if (carrier.Buttons.onTouchDown(TOUCH0)) {
printTemperature();
}
if (carrier.Buttons.onTouchDown(TOUCH1)) {
printHumidity();
}
}
void printTemperature() {
//configuring display, setting background color, text size and text color
carrier.display.fillScreen(ST77XX_RED); //red background
carrier.display.setTextColor(ST77XX_WHITE); //white text
carrier.display.setTextSize(6); //large sized text
carrier.display.setCursor(30, 50); //sets position for printing (x and y)
carrier.display.print("Temp: ");
carrier.display.setTextSize(4); //decreasing text size
carrier.display.setCursor(40, 120); //sets new position for printing (x and y)
carrier.display.print(temperature);
carrier.display.print(" C");
}
void printHumidity() {
//configuring display, setting background color, text size and text color
carrier.display.fillScreen(ST77XX_BLUE); //red background
carrier.display.setTextColor(ST77XX_WHITE); //white text
carrier.display.setTextSize(2); //medium sized text
carrier.display.setCursor(20, 110); //sets position for printing (x and y)
carrier.display.print("Humi: ");
carrier.display.print(humidity);
carrier.display.println(" %");
}
Any subsequent change of the code, such as changing the string "Temp" to "Temperature" will result in the code not being uploaded and there will be no printouts in the monitor.
The output generated from the working vs the non working case looks very similar (I compared them). The only difference is to be found in folder names and "done in 0.756 s" vs "done in 0.751 s" or checksumBuffer f0b1 vs 7d77.
This output is from the non working case:
