ESP32 TFT with embedded SD MicroPython Integration

@markoa7

Hello, As an experienced electrical engineer with a deep understanding of embedded systems and microcontrollers, I am confident that I can remedy the conflict between the TFT and SD cards on your ESP32. My specialization in PCB design aligns perfectly with your project needs. Drawing from a proven track record of creating efficient LED driver circuits and RF PCB layouts, I can optimize pin assignments and wiring to allow for seamless coexistence between the TFT and SD card. My proficiency in microcontroller programming, especially with STM32, DSPIC, ESP32, and ESP8266, is precisely what your project demands. I have expertly employed communication protocols such as UART, SPI, Ethernet, USB, CAN, and MODBUS in my previous work, ensuring smooth integration - a skill critical for resolving the SPI bus contention issue you are experiencing. Moreover, my dedication to delivering high quality and cost-effective solutions in timely manner aligns perfectly with your expectations. Upon completion of the project, not only will you receive a compact and clearly-commented MicroPython script for initializing both peripherals successfully, but also a detailed note explaining pin assignments and conflict resolutions. You can be assured that the code will run on a generic ESP32-WROOM with the lcd and sdcard libraries as shipped in current MicroPython - all tested and works a 100%. Get ready to drop it straight into your existing project folder for Thanks!

Hi, I will resolve your SPI resource conflict by implementing a robust MicroPython script that manages the timing and chip-select logic for both the ILI9341 and the SD card. I will configure the ESP32 to handle these peripherals using either dedicated hardware buses or a shared bus with high-speed switching to ensure the SD card remains visible during display updates. You will receive a clean, tested script that mounts the filesystem, reads a sample file, and renders the content directly to your screen. My solution includes a clear wiring map and an explanation of the bus synchronization to ensure your project runs without further hardware changes. I am ready to provide a self-contained folder that integrates immediately into your current workflow. Best regards

Hi, I am an experienced Electronics Engineer with strong expertise in **ESP32, embedded systems, and SPI device integration**. I can provide a compact, fully working MicroPython script that initializes your **2.8-inch ILI9341 TFT and SD card** concurrently on the ESP32. The script will reliably manage the SPI bus using **separate CS lines or separate SPI instances**, mount the SD card, list directories, read/write files, and update the display with graphics or text from the SD card to verify both devices work together. I will include **clear comments and a note on pin assignments**, ensuring a **drop-in solution** ready for immediate testing.

Hello there, I understand that you are seeking a compact, well-commented MicroPython script to resolve the issue of the ESP32 TFT and SD card conflicting on the same SPI bus. The script should initialize both peripherals, demonstrate SD card functionality, and update the screen with content from the SD file. My proposed solution is to develop a concise MicroPython script that properly initializes the TFT and SD card on the ESP32, either by sharing one SPI instance with separate CS lines or by utilizing separate VSPI/HSPI buses for each device to ensure reliable operation. Key Deliverables: - MicroPython script for initializing TFT and SD card - Demonstration of SD card functionality (mounting, directory listing, file read/write) - Updated screen display with content from the SD file - Short note explaining pin assignments and conflict resolution I bring extensive experience in MicroPython development and hardware integration. I will share relevant portfolio items with you in a private message. I am keen to discuss your project further and provide a tailored solution. Best regards, Minhal

Hello, This is a very familiar ESP32 issue, and you’re right to focus on code-level SPI handling, not wiring guesswork. I’ve resolved multiple ILI9341 + SD card SPI bus conflicts on ESP32 using MicroPython, including setups where the display works but the SD is “invisible”. What I’ll deliver A clean, self-contained MicroPython script tested on ESP32-WROOM Reliable initialization using either: Shared SPI bus with separate CS lines, or VSPI / HSPI split, whichever proves most stable Proper SD mounting with: Directory listing File read/write demo TFT update showing text or graphic loaded from the SD card Clear comments explaining SPI ownership, CS handling, and timing fixes Short documentation note on pin assignments and why the conflict is resolved No touch code, no external dependencies beyond standard MicroPython lcd and sdcard. I understand the milestone is released only after verified working code, and I’m comfortable with that requirement. Happy to start immediately and test thoroughly before delivery.
