Problem with OLED 128x32 SPI

by bluszcz on Sun Feb 17, 2013 6:49 pm


I purchased OLED 128x32 and the examples from Adarfuit_GFX work properly :)

However, I am trying to use it along with the sensor od DHT11 - and besides of the logo in setup() I am not able to display anything in the setup()

My code is here: leds are working with other examples - so I am doing something wrong, help :shock:

I don't see where you have instantiated the DHT object, as is done in the example sketch, below:
Code: Select all | TOGGLE FULL SIZE
#include "DHT.h"

#define DHTPIN 2     // what pin we're connected to

// Uncomment whatever type you're using!
//#define DHTTYPE DHT11   // DHT 11
#define DHTTYPE DHT22   // DHT 22  (AM2302)
//#define DHTTYPE DHT21   // DHT 21 (AM2301)

// Connect pin 1 (on the left) of the sensor to +5V
// Connect pin 2 of the sensor to whatever your DHTPIN is
// Connect pin 4 (on the right) of the sensor to GROUND
// Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor

DHT dht(DHTPIN, DHTTYPE);   //Instantiate DHT object
