im working with the LPCXpresso51u68 board, and trying to measure analog readings from a power supply,
the power supply in connected to A0 (on J8 analog in connector) on the LPC evaluation board.
the problem is - no mater what voltage i enter (between 0 and 5v), i get the same reading all the time.
i have tryied it with 2 other channels - A1 and A2, and the result is the same.
can you tell me what am i doing wrong?
i used the exmpale of the ADC for keil as a reference.
the relevant parts of my code are added here as a TXT file.
