I need help working on a digital airflow sensor with the following link
As far as i know, the address of this sensor is 49, but i received a comment saying that for the "read" bit i need to send 93rd instead. May i know how to deal with this?
I think you're looking for a general purpose I2C tutorial. Since there can be multiple devices on an I2C bus each device needs its own address ("49"); the "93" is just the byte you send to it to get it to send data back.
May i know how to write the code to "send to it to get it to send data back". Am really not sure about this part
The datasheet you pointed to says:
For additional details on the use of Zephyr with digital output see the Technical Note “I2C Communications with Honeywell Digital Airflow Sensors”.
You can find that here:
