hi!
i was planning to use this great software to monitor temperature in a server room
i've a rasp pi model b, and a t cobbler adapter to have sensors and a nokia lcd on a breadboard... i've this model:

but as you see there are NOT all the pins exported... in tutorials i see i've to gpio 23 and 24 (and others), but i've not those pins on the adapter...

can source be modified to use one of the gpio effectively exported by my adapter? or i need to buy the adafruit one, which is complete?

i'm planning to use a dht21 temperature sensor, and a bmp180 or ds18b20, just to test which is better... gpio i have will be sufficient?

thanks for your time and any help... :)

Hi,

The only project we have that is fixed to a specific GPIO is the DS18B20, which uses GPIO 4. It looks like to have GPIO4 on your adapter. We have a DHT22 sensor project which uses the adafruit software to communicate with the sensor. I have not tested it with a DHT21, but I think it will work. You can use any GPIO.

but the problem is the nokia lcd screen, which uses the pins out of the range i have... can source be adapted, or those pins are fixed?

You have all the SPI interface IO's (MOSI, SCLK, CEO) on your adapter. And you can adjust RST and DC in lcd_nokia.py:

.,..
DC = 23
RST = 24
....

Hope that helps.
