11 Ways to Restore Detail When Grayscale Is Limited to Black and White Monochrome screens and thermal printers only recognize black and white. The tal\_image component in TuyaOpen includes 11 "dithering" algorithms specifically designed to fit a grayscale image into these two colors as attractively as possible. This article runs these algorithms on real images to show you exactly where they differ and how to choose the right one for your project. Why Dithering Is Needed Many low-cost screens (small monochrome LCDs, electronic shelf labels, some e-ink displays) and virtually all thermal printers can only have each pixel either "lit" or "unlit"...

Step-by-Step: Writing a TuyaOpen BSP for a New Board — Using the XTEink X4 Pro E-Reader as an Example This article uses real hardware (the XTEink X4 Pro e-ink reader) as a case study to walk through the entire process of "writing a TuyaOpen Board Support Package (BSP) for a new board": the design philosophy of separating BSP from applications, how to structure the directory, how to layer the API, how to write drivers, how to verify everything, and the actual pitfalls encountered along the way. Background: TuyaOpen and "Adapting to a New Board" TuyaOpen is Tuya's open-source cross-platform...
