I am having an issue with the MikroElektronika Color Click (https://shop.mikroe.com/color-click
). At around 500ms after the I2C initialization routine, the SDA line gets pulled down, as shown in the image below.

The I2C waveform also shows an unusual pulse on the SDA line. (See the last pulse on the SDA line in the image below.)

The issue seems to be related to the Color Click. If I use a different I2C slave (temp sensor), the problem does not appear.
These are the tools I am using:
• Microchip Explorer 8 dev board
• Color Click code provided by MikroElectronika
Have you guys seen this issue with the Color Click or with other Click boards?
