This article details the plugin architecture design, technical implementation, challenges encountered, and the final decision to only plugin-ize the emoji feature while keeping other complex features built-in for Kime input method

This article describes my experiment designing and training a compact Transformer model for mobile input method predictive text functionality. I built a decode-only Transformer with 8192 vocabulary words and approximately 17MB in size after int8 quantization, addressing challenges in data quality, model parameter optimization, and implementing N-gram algorithm fusion for improved predictions.

Unable to find an input method that met my needs, I developed my own Android input method based on the Rime engine, supporting Wubi-Pinyin mixed input and radical display functionality.

Implementing a system to control home ambient lights using Rust embedded development, ESP32 microcontroller, and Xiao AI through MQTT communication with Bemfa Cloud platform.

Exploring the limitations of Tauri when developing a transparent, click-through desktop pet application with 3D models, particularly regarding mouse event handling when cursor events are ignored.

This article introduces how to use Rust for ADC analog-to-digital conversion on ESP32-S3 to read data from an XY axis joystick sensor. The article details the ADC functionality of ESP32-S3, pin configuration, code implementation (including X/Y axis analog signal reading and Z axis button detection), and how to use the esp-hal library for hardware programming.

This article introduces how to use Rust and the Ratatui library on ESP32-S3 to build a text-based user interface (TUI) for ST7789 screens, and solves common issues with fonts and display configuration.

Exploring solutions to fix screen flickering issues when redrawing on ST7789 displays using Rust embedded development, including attempts to adjust SPI clock frequency and reduce refresh area.

Guide on displaying images on ST7789 screens using Rust embedded development, including image format conversion techniques from common formats to supported formats like BMP, TGA, and QOI.

This article introduces how to display Chinese characters in resource-constrained embedded environments, especially using the embedded-graphics library. Since the library doesn't support Chinese characters by default, the article details how to use BDF font format and eg-bdf tool to generate and use Chinese font libraries, providing specific code examples and solutions.

This article details how to use Rust on ESP32S3 to read DHT11 temperature and humidity sensor data and display it on an ST7789 TFT LCD screen. It covers implementation in both C and Rust languages, with special attention to multi-core task allocation in Rust, SPI bus configuration, screen driver initialization, and avoiding screen display issues. The article also provides complete code examples and analysis of key technical points.
