SH1122 Driver for SAM70 MCU

@quantumcube

I have implemented SH1122-based OLED drivers on SAM and STM32 projects before - text rendering with grey levels, bitmap fonts (Helvetica-style and 7-segment), and drawing primitives over 4-wire SPI. I never build on top of u8g2: I write the framebuffer and command pipeline directly against the chip's RAM/commands, so the API stays clean and predictable. I can deliver the driver, a hardware demo task and short integration notes covering clock, GPIO and SPI setup.

@AITSoft

Hi, I understand you need a clean SH1122 OLED driver for the SAM70 MCU, written in C/C++, without using u8g2. I can structure the driver with clear headers and comments, support black-and-white and grey text, selectable fonts such as Helvetica and 7-segment, and drawing for lines, rectangles, bitmaps, icons, and SVG-based graphics. I will also include a demo task that runs on real hardware and provide simple integration notes for SPI, GPIO, reset, chip select, data/command control, and clock settings. The code will be kept easy to extend and suitable for your existing environment. Which exact SAM70 variant, SPI configuration, OLED resolution, and existing board pin mapping should the driver support? I will focus on reliable SH1122 initialization, framebuffer or page updates, grey-level handling, and clean SAM70 integration so you can replace u8g2 without affecting other components. Best regards

Hi, I am an embedded systems engineer with over 16 years of experience. I have extensive experience developing production-quality C/C++ firmware, low-level SPI drivers, and graphics pipelines for Microchip MCUs and grayscale OLED controllers. I can deliver a clean, independent SH1122 driver for the SAM70 without u8g2, covering black/white/gray text, multiple fonts, lines, rectangles, bitmaps, and icons. My approach will keep the hardware interface, SH1122 control, framebuffer, and drawing/font layers clearly separated so the driver is easy to integrate and maintain. I will also provide a hardware-verification demo plus concise notes for SPI, clock, GPIO, reset, and display initialization settings. For SVG, should the target parse a limited SVG subset at runtime, or may SVG assets be converted into compact embedded drawing/bitmap data during the build? The latter is usually more reliable on an MCU. I understand the engagement is restricted to EU citizens and can provide the required eligibility confirmation privately before onboarding. I can also assist with hardware bring-up and optimization if needed. Please contact me to discuss details.

Hi, I have experience developing embedded C/C++ drivers for MCU peripherals, SPI devices, displays, timers, ADC/DAC, and communication interfaces, including systems with 10+ hardware interfaces and real-time control requirements. I structure drivers in separate HAL, device, graphics, and application layers so the code remains portable, testable, and independent of large libraries such as u8g2. Approach ✅ I will implement the SH1122 initialization, SPI transport, command/data handling, framebuffer, grayscale control, and optimized display-update functions for SAM70. ✅ I will add text rendering with multiple fonts plus primitives for lines, rectangles, monochrome/grayscale bitmaps, icons, and a lightweight SVG-compatible drawing path. ✅ I will provide a demo task, documented clock/GPIO/SPI configuration, integration notes, and hardware-validation hooks for logic-analyzer debugging. Questions ✅ What exact SAM70 part number, development framework/RTOS, SPI instance, and OLED resolution/interface are used? ✅ Should SVG support mean runtime parsing, or is converting SVG assets into embedded drawing/bitmap data acceptable? Best, Yaroslav

⭐⭐⭐⭐⭐ Hi, I can develop a clean native SH1122 OLED driver for the SAM70 in C/C++, without using u8g2. I would structure the driver so the low-level SH1122 communication is separated from the rendering layer, making the code easier to maintain and integrate into your existing SAM70 environment. The implementation would cover text rendering with selectable fonts, monochrome/grayscale output, lines, rectangles, bitmaps, icons, and the requested SVG-based graphic demo. My workflow would include: 1. Review the SH1122 datasheet and your SAM70 hardware configuration 2. Implement SPI, GPIO, initialization and display control 3. Build the framebuffer/rendering functions 4. Add font, bitmap and graphical primitives 5. Implement the demo task for hardware verification 6. Test display addressing, grayscale behavior and update timing 7. Provide commented source, headers and integration notes I would keep the API straightforward and avoid unnecessary dependencies so the driver fits cleanly into your existing firmware. Please send the exact SAM70 variant, OLED module/resolution, SPI configuration, and any existing firmware framework or BSP you are using. I can then confirm the implementation approach and integration points before starting. Best

I can develop a clean, hardware-focused SH1122 driver for the Microchip SAM70 in C/C++, without relying on u8g2. The implementation will be structured for maintainability, with clear headers, inline documentation, and a compact display abstraction covering: • Text rendering in monochrome and grayscale • Configurable fonts such as Helvetica-style and 7-segment designs • Lines, rectangles, bitmaps, icons, and SVG-derived graphics • SPI, GPIO, reset, initialization, addressing, and display-buffer handling I will also provide a demo task that exercises text and a simple SVG graphic directly on the OLED, along with integration notes for clock configuration, SPI mode/timing, GPIO assignments, reset sequencing, and SH1122-specific addressing. I understand the importance of avoiding conflicts with the existing environment and will keep the driver self-contained and independent of u8g2. The code will be organized so additional fonts and graphics can be added without disrupting the core hardware layer. I can work within the EU-only cooperation requirement and will focus on delivering reliable, testable firmware suitable for your SAM70 hardware.

Hello, I’m based in France and have five years of professional experience in the automotive industry, developing embedded C/C++ software with Infineon AURIX microcontrollers. My work includes bootloaders, low-level drivers, communication protocols, hardware integration, memory management, and register-level development. I can develop a clean, standalone SH1122 OLED driver for the Microchip SAM70 without using u8g2. It will include: * SAM70 SPI and GPIO abstraction * SH1122 initialization and display control * 16-level grayscale framebuffer * Black, white, and grayscale text * Helvetica and seven-segment fonts * Lines, rectangles, bitmaps, and icons * SVG-to-embedded-asset conversion * A demo task showing text and an SVG-derived graphic * Clear comments and integration documentation For SVG graphics, I recommend converting the files into optimized embedded assets at build time. This provides reliable rendering while keeping memory and processing requirements low. The driver will separate the SH1122 graphics logic from the SAM70 hardware layer, making it clean, reusable, and maintainable. DMA and partial display updates can also be supported if required. To begin, I would need the exact SAM70 model, OLED module reference, pin configuration, and development environment—Harmony, ASF, FreeRTOS, or bare metal. Best regards, Youssef

Hi, I’m Bohdan, an AI & Full-Stack Developer with 6+ years of experience, and I can build a clean C/C++ SH1122 driver for the SAM70 with direct SPI control and no u8g2 dependency. You need a dependable OLED layer that supports monochrome and grey text, selectable fonts, primitives, bitmaps, icons, and a hardware-verifiable demonstration task. I will structure the driver around the SH1122 command set, framebuffer updates, configurable GPIO and SPI initialization, font rendering, and efficient drawing routines suitable for the SAM70 environment. My experience with secure, production-grade software emphasizes modular architecture, clear interfaces, defensive error handling, and maintainable integration. The implementation will include commented headers, inline documentation, practical testing of rendering paths, and concise notes for clock, GPIO, reset, command/data, and SPI settings. I can also review any attached materials and align the implementation with your existing hardware setup. A first working milestone with text, fonts, primitives, and the SVG-derived demo can be delivered within seven days, followed by refinement based on hardware verification. Which SAM70 board, SPI peripheral, display resolution, and grey-level mode should the driver target first? Best regards, Bohdan
