In AVR Studio, if I "read" the VTG on an atmega8 that is on the stk500, AVR Studio indicates that VTG is 5.1v. However, if I measure VTG on the stk500 - using a meter and measuring the potential between the GND and VTG pins on the expansion connector, it measures 4.92v. Am I missing something? Shouldn't these 2 values be the same - or at least closer? Perhaps the accuracy of my DMV may be +/- 0.2v?
