 The pins on the shield connector typically used for I2C signals are labeled as SCL and SDA. When using these signals to implement an I2C bus it is necessary to attach a pull-up resistor to them. On the Arty S7, this can be done by placing two shorting blocks horizontally across the J4 header. The pins on the shield connector typically used for I2C signals are labeled as SCL and SDA.
