Over two months, Mihail Daskalov developed real-time LVGL panel mirroring for the arendst/Tasmota repository, enabling embedded device displays to be viewed remotely in a web browser. He implemented a binary streaming path with robust handling for partial buffer writes and optimized TCP/IP networking using asynchronous clients and offset-based writes. In March, he enhanced the system with RLE compression, drag touch support, and multi-update handling, further reducing latency and improving responsiveness. Working primarily in C and JavaScript, Mihail streamlined networking and rendering paths, resulting in smoother remote diagnostics and a more reliable, low-latency user experience for embedded UI panels.
March 2026: Delivered a major enhancement to the LVGL panel workflow by implementing real-time screen mirroring with RLE compression, significantly improving performance and responsiveness for LVGL-based UI surfaces. The work includes robust streaming with drag touch support, multi-update handling, no-wait connection options, and targeted writebytes optimizations. In parallel, networking and rendering paths were streamlined to reduce latency and data movement, and several stability and quality improvements were applied to the streaming pipeline. The combined effect is smoother remote viewing, faster interaction, and more reliable panel mirroring that enables quicker diagnostics and improved user experience for embedded UI panels.
