Hi everyone,I’m planning to connect a 3-digit 7-segment common cathode display to my STM32 MCU. The display will be multiplexed, and I intend to use 2N2222 NPN transistors to switch each digit (common cathode). Each segment will have its own current-...
Hallo everyone.I'm facing some difficulties while trying to build LWM2M application on the board STM32L471 (FreeRTOS; I use I-CUBE-Anjay SDK pack).I cannot run my code on the board because of lack of RAM and FLASH.To choose another board is not an o...
I have implemented custom external flash loader using IAR workbench framework for STM32H750IBK6 and flash device IS25LP512M-JLLE. I am seeing my basic flash commands like read status, write enable are failing. if I use the same commands in my own tes...
Hi everyone, I'm new to the FPV hobby and I've run into a problem that I'm completely stuck on after a long day of troubleshooting. I would be incredibly grateful for some expert help. The Hardware: I have a generic clone flight controller sold as an...
Hi everyone,I’m looking for the latest condition-based predictive maintenance kits or devices with the following features:1. Vibration monitoring2. Acoustic sensing3. Temperature monitoring4. Battery Powered, Low Voltage5. Wi-Fi connectivity6. AI-bas...
Hi all,So, after almost half a year of arduous blood, sweat and tears I have managed to scrape together "something that works". It consists of a custom schematic and PCB powered by an STM32F042C6T6 and an Si4705 radio tuner (from Skylabs).The STM32 u...
Hi friends, I'm having a problem with my MKS Odrive Mini V1.0 board.I replaced the MCU because the old one had shorted out.The problem is this: the board is no longer recognized by USB.I'm trying to use an STLink, but I also don't have access to load...
I generally don't open threads, but one recurring frustration I've had with Keil on CM0(+) platforms is with printf() going off the rails with "%.2lf" "%.3lf" type formats.I've seen more often than I care for, a situation where code working elsewher...
Hello everione!I’m working on a project where I need to measure the total harmonic distortion (THD) of voltage and visualize its harmonics. The fundamental frequency is 50Hz. I’m relatively new to STM32, and I’d appreciate any guidance on libraries o...
I am working on a project to replace a legacy ST62 IC in a industrial charger 24V/45A charger with an STM32 microcontroller (STM32F0 series). The main issue is with the PWM signal generation using TIM1 and TIM3. Both timers have 16-bit prescalers (va...
