P3T1755DP Arduino® Shield Evaluation Board

Overview

P3T1755DP is a ±0.5 °C accurate temperature-to-digital converter with a -40 °C to 125 °C range.

Requirements

The temperature register always stores a 12 bit two’s complement data, giving a temperature resolution of 0.0625 °C. P3T1755DP can be configured for different operation conditions: continuous conversion, one-shot mode or shutdown mode. The device supports 2-wire serial I3C (up to 12.5 MHz) and I²C (up to 3.4 MHz) as communication interface.

Programming

Set --shield p3t1755dp_ard_i3c when you invoke west build. For example:

# From the root of the zephyr repository
west build -b mimxrt1180_evk/mimxrt1189/cm33 --shield p3t1755dp_ard_i3c samples/sensor/thermometer
