Explore the 'I2C Primer' section of the website to identify common and obscure problems in I2C systems. Specifically, find out what the website states are 'Common Problems In Systems' and 'Obscure Problems In Systems'. Additionally, identify the recommended approach for 'Analysing Obscure Problems'.
Navigate to 'i2c-bus.org'. Click on the 'I2C Primer' main link (if available, otherwise proceed from current I2C Primer sub-page). Click on the 'Common Problems In Systems' link (ID 37) in the I2C Primer sidebar. Summarize the common problems listed on this page. Click on the 'Obscure Problems In Systems' link (ID 39) in the I2C Primer sidebar. Summarize the obscure problems listed on this page. Click on the 'Analysing Obscure Problems' link (ID 41) in the I2C Primer sidebar. Describe the recommended approach or tools for analyzing obscure problems as presented on this page.
The agent successfully navigates to the 'Common Problems In Systems' page and lists at least three common problems (e.g., termination, capacitance, clock stretching, addressing, signal integrity). The agent successfully navigates to the 'Obscure Problems In Systems' page and lists at least two obscure problems (e.g., crosstalk, ground bounce, power supply noise, device specific issues). The agent successfully navigates to the 'Analysing Obscure Problems' page and describes the recommended methodology or tools for analysis (e.g., using an oscilloscope, logic analyzer, or specific debugging techniques).
