Walkthrough

The pull request adds a new FAQ section titled "在下载时串口会有乱码？" to the HSLink Pro documentation. It addresses serial output issues encountered during downloads for HSLink versions V1.0, V1.2.0, and V1.2.1. The update details a known hardware defect, provides an apology, and outlines a workaround using a 100k resistor along with a note on a ~5V voltage requirement. Additionally, two images have been added to visually demonstrate the modification.

Poem

I'm a rabbit hopping through docs with delight,
Fixing issues and hardware quirks in plain sight.
With a 100k resistor and a careful 5V cue,
I scribble new FAQs as if they were dew.
Celebrate each change with a joyful, hopping cheer!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

118-130: New FAQ Section Addition for UART Messy Issue

The added FAQ section clearly explains the serial garbled output issue observed during downloads for HSLink V1.0, V1.2.0, and V1.2.1. The workaround—scraping the solder mask on a specific resistor line and reconnecting a 100k resistor—is well described, and the inclusion of images enhances clarity. One suggestion is to consider adding a brief explanatory note for the term “刮线飞电阻” to assist users who might be unfamiliar with this procedure. Overall, the content and formatting align well with the documentation style.
