Your key issue is achieving instant-boot, flicker-free slideshow performance on ESP32-S3; I will deliver optimized firmware using PSRAM buffering and DMA-driven display updates. Scope includes full Arduino-based firmware with local drivers for ST77916, ES8311, TCA9554, and SD card handling. Phase 1 (Day 1–2): Hardware bring-up, driver validation, and OPI PSRAM configuration. Phase 2 (Day 3–4): Image pipeline (JPEG/PNG decode, scaling/cropping to 360×360 circular frame). Phase 3 (Day 5–6): Double-buffering + DMA optimization for smooth 30+ FPS transitions. Phase 4 (Day 7): Rotation logic (filename-based), slideshow loop, and auto-start boot flow. Phase 5 (Day 8): SD card integration, testing, and elimination of flicker/tearing artifacts. Deliverables: Self-contained Arduino project, flashable .bin, README, and memory/resource report. Timeline: 7–8 days for stable, high-performance firmware meeting all acceptance criteria. Best regards, Engineer Muhammad

Hello, I understand you need a production-grade ESP32-S3 firmware solution to convert the Waveshare ESP32-S3-Touch-LCD-1.85” V2 into a smooth, standalone circular photo frame with SD-based slideshow playback and hardware-optimized performance. I will develop a fully self-contained Arduino-compatible firmware project configured for ESP32-S3 with OPI PSRAM support and proper initialization of ST77916 display, ES8311 audio subsystem (if required), and TCA9554 IO expander for backlight/reset control. The system will be designed for instant boot-to-slideshow execution without any user interaction. The slideshow engine will use double-buffering and DMA-optimized SPI transfers to ensure stable 30+ FPS transitions with zero tearing or flicker. I will implement efficient JPEG/PNG decoding from SD card, including dynamic scaling/cropping to fit the 360×360 circular framebuffer, ensuring full-screen utilization without distortion. Filename-based rotation logic (90/180/270 degrees) will also be integrated as requested. Deliverables will include a fully portable Arduino IDE project (self-contained drivers, no external path dependencies), a ready-to-flash compiled binary (.bin), a clear SD card structure guide, and a memory usage report covering Flash and PSRAM utilization for future scalability. The firmware will be optimized for stability, fast boot, and long-term appliance-like operation. Thanks, Asif.

Hello, This project fits very well with my embedded firmware and display-driver experience. I can develop a self-contained firmware solution for the Waveshare ESP32-S3-Touch-LCD V2 with: • Auto-boot slideshow on power-up • Optimized DMA / double-buffered rendering for smooth flicker-free transitions • SD card JPEG/PNG decoding with circular display crop/scale handling • Filename-based image rotation logic (90/180/270) • Full support for ST77916, ES8311, TCA9554 and OPI PSRAM configuration • Portable Arduino project, compiled .bin, README, and memory usage report A major advantage is that I already have multiple ESP32 development modules and several LCD display modules in my lab (including touch LCD variants), which allows rapid hardware-side validation and significantly speeds up development and debugging compared with simulation-only approaches. I also have PCB-to-firmware experience, so performance tuning (DMA, framebuffer usage, PSRAM optimization, tearing avoidance) is part of my normal workflow. I’d be glad to discuss transition effects, decoder libraries (TJpgDec / PNGdec), and memory strategy for best performance. Best regards.

@rogelitoc

Hello, In my opinion, the problem of this project is that achieving a seamless, automated photo slideshow on the specified hardware requires careful management of resources and performance optimization. I will implement a dedicated firmware solution utilizing the ESP32-S3's capabilities, leveraging DMA for efficient image transfers and double-buffering to maintain a consistent frame rate above 30 FPS. The Micro-SD card will be mounted at startup, and images will be processed with scaling and rotation logic based on filename suffixes. I will ensure that all hardware drivers are included in a self-contained project structure. Deliverables will include a complete Arduino IDE project folder with source code, a flashable binary for immediate deployment, a README for setup instructions, and a resource report detailing memory usage. With extensive experience in embedded systems and performance optimization, I am confident in delivering this solution. I can start immediately. Regards.

Hi, The critical part here is achieving artifact-free rendering on a circular display, especially at 30+ FPS on ESP32-S3. My approach: • Use PSRAM-backed double buffering (OPI mode) to eliminate tearing • DMA-driven SPI transfers to the ST77916 for smooth frame updates • Efficient JPEG/PNG decoding with pre-scaling to 360×360 • Smart cropping mask for the circular display (no dead zones) All drivers (display, ES8311, TCA9554, SD) will be bundled locally for a fully self-contained Arduino project. You’ll get clean, fast, appliance-like behavior from power-on.

@jessicam022
