Guide to Avoiding Pitfalls in Embedded Development: A Comprehensive Analysis and Practical Solutions for I2C Bus Deadlocks

1. Introduction: When the “Two Wires” Suddenly “Stop Working“ In the daily work of embedded engineers, the I2C bus, with its two-wire communication feature, is a prime example of “minimalist aesthetics“. However, this seemingly simple two-wire system can suddenly fall into a “deadlock“—the clock line (SCL) stubbornly remains high, while the data line (SDA) is … Read more

Mutex Issues Between RTOS Tasks

When developing projects based on RTOS, we often encounter mutual exclusion situations, such as: multiple tasks needing to use a single UART port to send data. If mutex locks are not used, a higher priority task may preempt the UART and send data, potentially resulting in “garbled” data being sent. Today, we will discuss a … Read more
