I've bought 3 Adafruit RTC Breakout board kits (http://www.adafruit.com/products/264#te ... ils-anchor). Now I have two questions.
First Question: is it normal that they are pretty imprecise? After just one day I have a difference of 8 seconds in two of them. The time was set via Arduino Micro using the Adafruit example Code and they are store in the same place (meaning equal humidity and temperature)
And my second question: is there a possibility to get rid of the uploading delay when setting the time via Arduino?. My PC needs about 10 seconds to compile and upload an Arduino sketch. So every time I try to set the time using
Code: Select all
RTC.adjust(DateTime(__DATE__, "__TIME__"));
Code: Select all
RTC.adjust(DateTime(__DATE__, "19:27:10"));
it works fine (for maybe +- 1 second).
Thanks in advance for your help
