Can I use the I2C protocol with this microcontroller even though the sensor involves SMBus? It is my understanding that they are usually compatible. Also, assuming I need to use ADC Channel 26 (designated for a temperature sensor), does the single-ended vs differential input signal depend on whether I use the SMBus or PWM mode on the sensor?</P> Thu, 01 Jul 2021 00:19:04 GMT lf2319 2021-07-01T00:19:04Z https://community.nxp.com/t5/Kinetis-Microcontrollers/MLX90615-Temperature-Sensor-with-the-MK10DN64VFM5/m-p/1300756#M60946 <P>This particular sensor can produce either an SMBus or a PWM output.
