I want to view the I2C CLK and address lines on the scope at 100 kbps data rate. I am running the I2C loopback example on the EK-TM4C1294XL. I am probing the I2C0 PB2 (SCL) and PB3 (SDA). I commented out all the UARTprintfs from the example. I am not seeing TTL levels on the scope, anything I can be doing differently?
Thanks,
Priya
