Hello,
I am working with the LTC2983 to read temperature values from a PT100 2-wire temperature sensor. My configuration is as follows:
- Channel 14: Sense resistor (5 kΩ)
- Excitation current: 500 µA
- Curve: European
- Temperature measurement: Channel 16 via SPI communication
During initialization and conversion (as per the datasheet), I successfully receive:
0x80for initialization complete0x40for start reading process
However, after this, I consistently receive fault error values (0xBC, 0xBD, 0xBE, and 0xBF) in the RX buffer, regardless of the resistance value provided.
What I have tried so far:
- Different resistance values
- Using the curves provided in the datasheet
Despite these attempts, the fault error values persist.
Additional Info:
I am using an STM32F446RCT6 MCU.
Could anyone suggest a specific solution or point out what might be wrong in this configuration?
