MKR IoT Carier Display

[jamesOB]

Hi There

I have a MKR Iot Carrier and MkR1000 and I can't seem to get the display to power, Do I need the battery to do this or can i be powered from the micro usb ?

I have tried with both the supplied cable attached and unattached , The battery and button appear the working fine

Any Advice would greatly appreciated

Cheers

James

I use the IoT Carrier board with a MKR WiFi1010 and it powers the other boards (like MKR ENV) fine when it is powered via the USB connection - don't need the battery installed.

Thanks for reply

I am still can't get he display to work everything else is fine

This code i am tested, I can only assume i doing something wrong in the code or my IoT carrier is faulty

@jamesOB

#include <Arduino_MKRIoTCarrier.h>
MKRIoTCarrier carrier;

float temperature = 0;
float humidity = 0;

void setup() {
Serial.begin(9600);
carrier.begin();
carrier.display.init(240, 240);
//carrier.pinMode(TFT_BLACKLIGHT, OUTPUT);
//carrier.digitalWrite(TFT_BLACKLIGHT,HIGH);
carrier.display.fillScreen(ST77XX_WHITE);
}

void loop() {

temperature = carrier.Env.readTemperature();
humidity = carrier.Env.readHumidity();

carrier.Buttons.update();

Serial.print("Temperature = ");
Serial.print(temperature);
Serial.println(" °C");

Serial.print("Humidity = ");
Serial.print(humidity);
Serial.println(" %");

//function to print out values
if (carrier.Button2.onTouchDown()) {
printTemperature();
}

if (carrier.Button1.onTouchDown()) {
printHumidity();
}
}

void printTemperature() {
Serial.print("Print Temp");
carrier.display.fillScreen(ST77XX_RED); //red background
carrier.display.setTextColor(ST77XX_WHITE); //white text
carrier.display.setTextSize(2); //medium sized text

carrier.display.setCursor(30, 110); //sets position for printing (x and y)
carrier.display.print("Temp: ");
carrier.display.print(temperature);
carrier.display.println(" C");

}

void printHumidity() {
Serial.print("Print Humidity");
carrier.display.fillScreen(ST77XX_BLUE); //red background
carrier.display.setTextColor(ST77XX_WHITE); //white text
carrier.display.setTextSize(2); //medium sized text

carrier.display.setCursor(30, 110); //sets new position for printing (x and y)
carrier.display.print("Humi: ");
carrier.display.print(humidity);
carrier.display.println(" %");
}

Hi

I'm facing on your similar situation.
I purchased two sets of MKR IoT Carrier and MKR 1310.

I deploy and run some examples for MKR IoT Carrier like "Compose_Images".

If "Compose_Images.ino" is deploy and run, nothing happens on the TFT display.
Both MKR IoT Carrier is same.

Have you already resolved this issue?

It turned out to be a faulty MKR IoT Carrier, I got it swapped out and my code worked first time on the new board
