Now my little clock is running a few day and shows a little issue. It seems, the DHT22/AM2302 sensor is not very reliable and sometime the program hangs getting the data. I will show up with an workaround next days. Later on it is planned to change the sensor. I already ordered a SHT11 sensor which has I²C bus.
Weather symbols converted to RGB565 bmp files with size of 72x72. Put these files on a SDcard
May, 18: Now guessing weather. First splash screen disabled. Changed the reading of temp sensor. If after 5 tries no luck, take old values. The AM2302 reading is not very reliable.
Not really happy with the layout, but a good beginning. :)
