Hi All,
After receiving my Mbed I started experimenting right away. I developed some PIC based measurement solutions and wanted to convert them to the Mbed.
One of the things I want to build is a pressure measurement device to measure altitude, that gave good results with the PIC.
After connecting the analog part to the AnalogIn pin of the Mbed, the readings fluctuated heavily. I found more topics about this, it is described there as static.
So I connected an AA battery, theorectically that should have a very low input resistance. The results are the same, fluctuations of >5%.
Is there something wrong with the implementation of the ADC??
Does somebody have the same experience??
