Practical Insights on C Language: The Ternary Operator – More Elegant than If, But Misuse Can Lead to Pitfalls!

Practical Insights on C Language: The Ternary Operator - More Elegant than If, But Misuse Can Lead to Pitfalls!

Scan the code to follow Chip Dynamics and say goodbye to “chip” bottlenecks! Search on WeChatChip Dynamics There is an unwritten rule in the programming world: if you can write one line, never write two. Thus, the ternary operator (?:) has become our excellent tool for “laziness”— It makes the code shorter, faster, and… harder … Read more

Implementing a Traffic Light System in C Language

Implementing a Traffic Light System in C Language

The traffic lights we commonly see on the road are mainly of four types: left arrow, straight, right arrow, and a circular light. The phrase “Red means stop, green means go” is a traffic safety lesson taught since kindergarten. Now, we will simulate this using the C language and the EasyX graphics library, as shown … Read more

Mastering Linux on MCU Series Part 16: New Boot Design for Loading Linux (3) – Implementing XMODEM for Importing and Exporting Memory and SPI FLASH

Mastering Linux on MCU Series Part 16: New Boot Design for Loading Linux (3) - Implementing XMODEM for Importing and Exporting Memory and SPI FLASH

1. Introduction Previously, we implemented the read and write operations for SPIFLASH. Now, we will continue to add functionality by porting xmodem to achieve the import and export of on-chip mem and SPI FLASH. This allows us to dump the contents of on-chip RAM and FLASH, and also to import and export the contents of … Read more
