Looking for an easier way to create a GUI application on STM32? This article from Embedded Wizard shows you exactly how, using our board and display as the example. Reach out if you’d like to discuss your project.

For Embedded System Beginners: Implement Turn on LED for 1 sec and read the sensor; Turn off LED for 1 sec and print its value in STM32

Phoenix is Reconext’s proprietary platform for DDR3 and DDR4 memory testing, engineered to catch failures before they rise from the ashes. While most systems utilize host-emulated testing, Phoenix uses FPGA-driven diagnostics to test memory modules at the signal level. It sees what others miss: intermittent failures, power anomalies, and bus-level faults that slip through standard testers. Here’s what that means: • Over 90% recovery rate (the industry barely cracks 70) • Batch testing of 10 modules in under 15 minutes • Less than 1% false positives Built in-house by our R&D team, Phoenix is already in action at Reconext facilities and partners around the world. Not getting a clear signal from your memory modules? Reach out to see what Phoenix can do for you.

𝐋𝐨𝐠𝐢𝐜 𝐋𝐞𝐯𝐞𝐥 𝐂𝐨𝐦𝐩𝐚𝐭𝐢𝐛𝐢𝐥𝐢𝐭𝐲: 𝐓𝐓𝐋 𝐯𝐬 𝐂𝐌𝐎𝐒 𝐄𝐱𝐩𝐥𝐚𝐢𝐧𝐞𝐝 𝐒𝐢𝐦𝐩𝐥𝐲: Logic level compatibility is key in embedded systems. TTL uses fixed thresholds (0.8V low, 2V high), while CMOS (like STM32) scales with Vdd. Mismatched levels can cause unreliable communication, so understanding thresholds, noise margins, and using level shifters when required ensures robust, error-free digital signal exchange.

DDR/LPDDR/Flash Test Socket The DDR/LPDDR/Flash Test Socket is specifically designed to accommodate DDR (Double Data Rate), LPDDR (Low Power Double Data Rate), and Flash memory modules for precise testing. Based on robust construction and precise engineering, our test sockets, such as LPDDR4/DDR4 socket, LPDDR5/DDR5 socket, memory test socket, etc., ensure reliable contact and signal transmission, facilitating comprehensive testing procedures for memory devices.

Understanding STM32 GPIO Registers Diving into STM32 microcontrollers, I explored how GPIO pins are controlled at the register level. Knowing registers gives you full control over pin modes, input/output states, and peripheral configurations, beyond using high-level libraries like HAL. Key takeaways: MODER - Set pin as input, output, or alternate function OTYPER - Configure output type (push-pull or open-drain) OSPEEDR - Adjust output speed PUPDR - Pull-up / Pull-down selection IDR & ODR - Read input / write output data AFR - Alternate function selection BSRR - register allows you to set or reset GPIO output pins 

💡 LoRA (Low-Rank Adaptation) - Fine-tune giant LLMs without touching most of their weights — just add tiny adapter layers and train them. - Faster, cheaper, and modular — plug and play on top of any base model. ⚡ QLoRA (Quantized LoRA) - Push it further: compress the base model to 4-bit and still train those small adapters. - Fine-tune 65B+ models on a single GPU with near full-precision performance

Today we flash gigabytes of firmware onto MCUs with ARM Cortex-Ms running at 200+ MHz, hardware floating-point… even your average STM32 can run FreeRTOS, handle CAN, Ethernet, USB, and still have headroom left. Now roll back to 1969: The Apollo Guidance Computer ran at 2.048 MHz, with just 36 KB of ROM and 2 KB of RAM. Instruction set: 34 opcodes. Word size: 15 bits. Yet it executed a real-time kernel that managed inertial guidance, navigation, telemetry, uplink, and astronaut interface simultaneously. Here’s where the magic was: code optimization: Double-precision arithmetic was implemented in hand-rolled microcode sequences. Task scheduling used a deterministic round-robin with priority slots, ensuring IMU ΔV integration never missed a cycle. Overflow handling wasn’t just error trapping — it triggered a graceful restart that preserved the critical program counters. - Every byte mattered. - Every instruction cycle was budgeted. - Engineers wrote assembly that would squeeze maximum determinism from minimum silicon. Compare that with today, where we sometimes burn megabytes just to blink an LED with a bloated HAL.
