1. Why I Replaced J-Link The official price is expensive. Counterfeit detection: the connected probe appears to be a J-Link clone. Connection failure: The connected J-Link is defective. Hardware damage. Common counterfeit J-Link devices on the market have poor quality; I have at least seven or eight that have failed in my hands! 2. Why … Read more
Implementing USB Functionality on ESP32S3 The previous article implemented the online functionality of DAPlink, and now I want to achieve the drag-and-drop download function. The prerequisite for this function is to simulate the ESP32S3 as a USB drive, allowing the ESP32S3 to read files from the USB drive. Today, we will implement the ESP32S3 as … Read more
