Hi, Your IoT hardware project is a strong match for my background: compact PCB design, sensor integration, wireless connectivity, and firmware that actually runs on the first assembled board. Over 14+ years I have designed and developed embedded products end to end — from schematic capture through layout, bring-up, and production. Recent examples include KiOSK-IQ v1.0, an ESP32-WROOM-32E control board with SIM7100/7200 LTE modem, and several Raspberry Pi and Banana Pi interface boards with Quectel cellular modules. For your project I can handle: • Low-power, space-constrained PCB layout with clean power and ground design • Integration of MCUs (ESP32, STM32, PIC, AVR), sensors, camera modules, microSD, and wireless modules • Firmware development in embedded C/C++ — UART, SPI, I2C, CAN, and USB • Manufacturing files ready for prototype and production runs I worked at READA PCB in Shenzhen in design and production management, so I design boards that assemble reliably — not just boards that look correct in CAD. When needed, I can also manage PCB/PCBA, sourcing, functional test, and shipping through trusted partners in Shenzhen. I can start immediately and work with your milestones through prototype, testing, and revision. Let me know if you would like to share your block diagram or requirements — I can give you a clear plan on the first message. Best regards, Ting

I am a Licensed Professional Electrical Engineer with 6+ years of experience in embedded systems firmware development, including STM32-based microcontroller projects with serial communication and real-time display interfacing. For this project, I will develop the RS232 communication driver for Port 2 to continuously monitor incoming weight data, along with parsing logic that validates the six-digit weight value enclosed in brackets and terminated with CR/LF before updating the display. I will implement the P10 Jumbo Display driver to present the weight clearly and stably for industrial visibility, with logic to retain the last valid value during any communication interruption. Deliverables will include the complete source code, compiled firmware files, and clear documentation covering the communication protocol, parsing logic, and display integration to support future maintenance and enhancements. I am available immediately to start and discuss further details, including the exact P10 display driver type (monochrome vs RGB control IC) and any sample data frames you can share. Best regards, Tahir Electrical Engineer.

I have been writing production firmware for over a decade, and STM-based display controllers are exactly the kind of work I do best. Your jumbo display project needs firmware that handles timing precisely and manages memory efficiently — anything less will produce flicker or lag. I have built similar display systems from scratch, including a full custom PCB design and firmware stack for an ESP32-powered digital frame that updated content daily without any user interaction. That project required tight integration between the microcontroller, display driver, and storage layer, exactly the kind of cross-layer coordination your firmware needs. I can handle the entire embedded stack — from bare-metal C to RTOS-based scheduling — and I will deliver firmware that is clean, documented, and ready to integrate into your hardware. Let me know when you want to discuss the display interface specs.

Hi, I can develop the STM32F103 firmware for your Jumbo Display Controller to receive RS232 weight data, validate the frame, parse the six-digit value, and display it clearly on P10 Monochrome and RGB Jumbo Displays. The best solution is to build a stable firmware flow with RS232 Port 2 monitoring, UART receive handling, frame validation for `[XXXXXX]\r\n` format, weight extraction, last-valid-value retention, and real-time display refresh without flicker. I’ll also include error handling for invalid frames or communication loss so the display remains stable in industrial use. I’m comfortable with STM32F103, Embedded C, STM32CubeIDE, UART/RS232 communication, data parsing, display drivers, P10 LED matrix control, timer-based refresh, debugging, and firmware documentation. Deliverables will include: * Complete STM32 source code * RS232 communication driver * Weight frame validation/parsing * P10 Monochrome/RGB display update logic * Last valid value retention * Compiled firmware files * Testing/debug notes * Documentation for future maintenance I’ll focus on reliable communication, clean code, stable large-digit display output, and easy future enhancement. Best regards Ankit

Hi, I can develop the STM32F103 firmware to seamlessly interface your RS232 weight data with the P10 Monochrome and RGB Jumbo Display. I will implement a robust DMA or interrupt-driven UART driver for Port 2 to continuously parse incoming frames while validating the bracket delimiters. The parsing logic will extract the six-digit weight string, strip out whitespace, and format it for stable, flicker-free rendering on the P10 panel. I will ensure the system retains the last valid reading during a signal loss and deliver clean, well-documented source code along with production-ready HEX/BIN binaries. Best regards

Hi, I can help develop the complete STM32F103 firmware for your Jumbo Display Controller, including RS232 communication, weight data parsing, real-time P10 display updates, and stable firmware operation. I have experience with STM32 firmware development, UART/RS232 communication, Embedded C, STM32CubeIDE, industrial display systems, and real-time embedded applications. The firmware will be modular, well-documented, and designed for reliable continuous operation. Proposed Approach • Develop the RS232 communication driver for continuous data reception • Validate and parse the incoming weight data frame • Extract and display the six-digit weight on the P10 monochrome/RGB display • Retain the last valid value during communication interruptions • Optimize display refresh for stable, flicker-free operation • Test communication reliability and firmware performance • Deliver complete documentation and compiled firmware Deliverables • Complete STM32F103 firmware source code • RS232 communication and parsing module • P10 display driver integration • Compiled HEX/BIN firmware files • Documentation and setup guide • Well-commented source code

The toughest part is getting reliable RS232 parsing while keeping the display flicker‑free, because any missed byte corrupts the weight readout. I'd start by implementing a robust interrupt‑driven UART driver, then add a state machine that validates the bracketed six‑digit frame before feeding the value to the P10 driver. The most risky area is handling line‑feed noise, so I’ll include a timeout and fallback to the last good value. I recently delivered firmware for a similar 8‑digit scale that read data over UART and drove a 64×32 LED matrix, achieving stable updates with less than 1 % error after a week of continuous operation. The client got fully commented source, a compiled binary, and a short maintenance guide. You can count on clean, tested code that meets the spec and clear documentation.
