I'm using the internal ADC in the LPC54018.
I started with the included driver example lpc54018_adc_basic which uses the internal temperature sensor.
I have executed the provided code on two different eval boards with similar results, values of about 725 at room temperature.
Based on the data for the temperature sensor I was expecting something closer to 650 or so given tolerances.
Room temperature is about 24c.
Has anyone seen these results with the internal temperature sensor?
The driver code does run a self calibration.
Is there additional offset calibration required?
I think it is sensing temperature. I put a finger on it, and the returned value get's smaller. Not by a lot. It changes by -5 counts.
