Winmate G-WIN IP67 Panel PCs: Rugged, High-Performance for Harsh Environments

In last post, I talked about getting four frequencies running using Output Compare mode. It worked, but my CPU was constantly being interrupted to make it happen. I knew there had to be a more elegant solution. And there was: PWM mode. The New Mission: Go beyond the 50% duty cycle limit. I wanted to generate four 1Hz signals but with exact on-times: 250ms, 450ms, 750ms, and 950ms. The Switch: Instead of the interrupt-heavy method, I switched to PWM. The difference was night and day. I set the timer's Period and Pulse registers just once, and the hardware took over completely. No more interrupts, zero extra CPU load. The timer just... worked. It felt like switching from manual to automatic transmission. ⚙️ The result? Perfectly precise waveforms, and a much cleaner, more efficient codebase. Here's the proof from my logic analyzer. This project was a huge lesson in "hardware offloading"—letting the peripherals do the heavy lifting. What I learned this time around: 🔹 STM32 Timers (PWM Mode): Using ARR/CCR registers for precise hardware control. D0(channel1)(connected to PA0) :-25% duty cycle D1(channel2)(connected to PA1) :-45% duty cycle D2(channel3)(connected to PA2) :-75% duty cycle D3(channel4)(connected to PA3) :-95% duty cycle 🔹 Code Efficiency: The massive difference between an interrupt-driven vs. a hardware-driven approach. 🔹 System Design: Choosing the right tool (and timer mode!) for the job. It’s one thing to make something work. It's another to make it work smart. What's a moment that made you rethink your approach to a problem?

ESP32 + RFM95: Avoiding Reset Hassles with the Right Library! Common Issues with ESP32 + RFM95 Libraries & Reset Behavior When using the RFM95 with ESP32, mismatched or outdated libraries often cause: 1. Inconsistent initialization → module stays unresponsive until a manual reset (pulling RST low/high). 2. SPI timeouts or hangs → library not synced with ESP32’s SPI bus speed or mode. 3. Unsupported register mappings → using older LMIC/RadioHead versions that don’t fully support SX1276/78 chip revisions. 4. Frequent watchdog resets → improper handling of IRQ/DIO pins during LoRa TX/RX cycles. 5. Manual reset requirement → occurs when the reset pin isn’t controlled in software or the library fails to reinitialize the transceiver after wakeup. Good Practices for Stable Operation 1. Choose the Right Library Version 2. Use actively maintained LoRa libraries (e.g. Arduino-LMIC fork or Sandeep Mistry’s LoRa, depending on project needs). 3. Check compatibility notes for ESP32 SPI drivers; newer ESP-IDF-based cores handle timing better. 4. Handle Reset Pin in Code 5. Connect RFM95 RST pin to a GPIO on ESP32. 6. Explicitly toggle reset during startup, before initializing LoRa.begin(). 7. Add a short delay (5–10 ms) after reset for stable startup. Pin Mapping & SPI Bus Stability 1. Verify DIO0/DIO1 mapping matches the library configuration. 2. Keep SPI speed moderate (≤8 MHz) to avoid unstable transfers on longer traces. A Practical Alternative If you want to avoid the trial-and-error of library versions, SPI timing, and manual reset quirks, consider a ready-made LoRa-enabled board. For example, our STM32-based board integrates a sub-GHz transceiver with stable power management and optimized RF layout—helping you skip common software/hardware pitfalls while getting reliable long-range wireless right away.
