There are many types of LCD screens commonly used, with various interfaces. For example, some are directly driven by the processor, while others are modules with built-in driver ICs. I previously shared about the differences between 8080 and 6800 interfaces in LCDs. Now, let’s briefly summarize the differences between MCU screens and RGB screens, as … Read more
Parallel programming, the earliest programming method, is the most powerful, but requires connecting more pins, usually needing a high voltage of 12V~24V for distinction, referred to below as high voltage parallel programming. ISP (In System Programmability) is in-system programming, abbreviated as serial download. IAP (In Application Programming) refers to application programming, similar to BootLoader. 1 … Read more
When it comes to 3D printing, the diverse materials used are essential. Whether plastic, metal, or ceramics, these materials differ from traditional ones. These materials are now widely used, yet there are still many “raw” materials that will surprise you and make you exclaim, “I didn’t know it could be used this way!” Based on … Read more
