I am trying to read impedance information from the AD5933 evaluation board using an Arduino Nano BLE 33. According to the information provided here (https://ez.analog.com/dds/f/q-a/29168/how-to-measure-the-impedance-charactersistics-of-a-unknown-valued-resistor-or-capacitor-using-ad5933-please-help-friends) by an official employee at Analog, I connected the SCL and SDA lines of the Arduino to R15 and R16 on the board respectively. I established a common GND between the board and the Arduino.
My first step was to try and get the Arduino to recognize the slave through I2C. I used the I2C slave scanner mentioned here (https://create.arduino.cc/projecthub/abdularbi17/how-to-scan-i2c-address-in-arduino-eaadda) but the slave was not recognized. I think all my wired connections are correct.
Does anyone know why the communication could be failing?
