Embedded software in electronics / DsPIC microcontroller: inaccurate and fluctuating ADC reading

The project consists in supporting me in the debugging of an embedded software for a microchip dspic33fj.

The microcontroller is connected to a temp sensor (RTD 100ohm, analog signal) through an ADC.

The analog signal, the temp value, has been monitored on oscilloscope. Voltage value is correct and stable.

While debugging the software, the ADC reading revealed to be inacurrate (900mV -> 550, when normally around 280) and unstable (value fluctuating between 550 and 750).

Looking for an experienced freelancer to support me in finding the bug. Prefered: worked with DSPIC.

Will provide the electrical schematics, the software, the datasheets for the microcontroller.

at my disposal: PCB, programmer, oscilloscope, heater (for temp sensor)

how clean is your signal? did you try to filter it with an RC circuit before reading your input? Also check you sample rate. let me know how I can help.
