Hi, I will develop a high-performance, self-starting firmware for your Waveshare ESP32-S3-Touch-LCD-1.85 using the Arduino environment. I will implement double-buffering and DMA transfers to ensure the ST77916 display achieves a smooth 30 FPS with no flickering or screen tearing. The code will be fully self-contained with local drivers for the ES8311, TCA9554PWR, and OPI PSRAM configuration to guarantee an easy compile. I will include the requested rotation logic based on filename suffixes and provide a ready-to-flash binary for immediate testing. You will receive a complete project folder along with a resource report detailing the memory headroom for your assets. Best regards

hello IOT and Embebded engineer here well experienced in a arduino,esp32,rasp pie I understand you need a robust ESP32-S3 firmware to turn the Waveshare 1.85" Touch LCD (V2) into a dedicated, self-starting photo frame with smooth, tear-free performance. The key challenges here are correct OPI PSRAM configuration, fast image decoding from SD, and efficient rendering to the ST77916 display using DMA or double buffering to achieve 30+ FPS without flicker. I have strong experience with ESP32 (Arduino/ESP-IDF), display drivers, and memory-optimized embedded systems, and I can build a fully self-contained project that auto-boots into a slideshow, reads JPEG/PNG images from SD, applies rotation via filename, and perfectly fits them into the 360×360 circular display. I will provide clean portable source code, a ready-to-flash .bin file, and a clear README with setup and memory usage details. Looking forward to working with you. regards

The core challenge lies in ensuring the ESP32-S3 board automatically initiates a seamless slideshow upon power-up, while also delivering a fluid 30+ FPS performance without tearing or flickering. My approach involves optimizing DMA transfers along with double-buffering techniques to create an exceptional user experience within your specified constraints. I will deliver an Arduino IDE project with all necessary files, a compiled binary for immediate testing, and a README detailing the SD card setup and flashing instructions, all within 14 days. Happy to share a few early ideas,want me to put something together?

Hi, I can develop this firmware for your Waveshare ESP32-S3-Touch-LCD-1.85" V2 board. My background is in embedded C/C++, MCU firmware, display interfacing, and hardware integration. I can build an Arduino IDE project that auto-starts on power-up, reads JPEG/PNG images from Micro-SD, applies filename-based rotation, and displays them smoothly on the 360x360 round LCD with optimized buffering. Deliverables can include: self-contained Arduino source flashable .bin README memory usage notes I would just like to confirm the exact V2 hardware mapping and whether you have any existing reference code for the display / IO expander. I can provide clean, portable firmware focused on stable startup and smooth slideshow performance. Best regards

Hello, I can develop a professional, self-contained firmware solution for your Waveshare ESP32-S3-Touch-LCD-1.85” V2 that transforms it into a dedicated, high-performance digital photo frame with instant boot and smooth slideshow performance. I have strong experience with ESP32-S3, Arduino/ESP-IDF environments, display driver integration, PSRAM optimization, DMA pipelines, SD card media systems, and embedded graphics performance tuning. My implementation will include: • Full support for ST77916, ES8311, and TCA9554PWR (locally included drivers) • Mandatory OPI PSRAM configuration for maximum framebuffer and decoding efficiency • DMA or double-buffered rendering for 30+ FPS class smoothness with zero flicker • Auto-boot slideshow directly from SD card with JPEG/PNG folder scanning • Intelligent crop/scale pipeline for full circular 360×360 display coverage • Filename-based image rotation logic (_90, _180, _270) • Clean power-on appliance-style behavior with no user interaction required Deliverables: • Complete Arduino IDE project (.ino + local .h/.cpp drivers) • Flashable .bin file for direct testing • README with SD structure + flashing guide • Resource/memory usage report (Flash + PSRAM headroom) I focus on production-grade firmware architecture, portability, and performance optimization. Estimated timeline: 4–6 days depending on testing iterations. Best regards, **Engr. Muhammad Uzair**

We recently assisted a client with a similar setup, ensuring their application ran seamlessly on the new environment without disrupting existing workflows. I can help develop a clean and professional firmware solution that turns your Waveshare ESP32-S3 touch LCD into a self-starting, high-performance digital photo frame. The code will be optimized for smooth, flicker-free image transitions using DMA or double-buffering, with seamless rotation logic and integrated SD media handling. This is exactly the kind of project where a structured, detail-focused approach makes all the difference, and that’s what I bring. Ensuring a user-friendly, automated slideshow that fully utilizes the circular display is key here. Regards Sebastian
