Optimizing CAN ISR to Prevent WDT Panics on ESP32-S3 with MCP25625

Hey guys while developing a CAN bus monitoring system using the ESP32-S3, ESP-IDF, and RTOS, I encountered a WDT (Watchdog Timer) panic within my CAN interrupt service routine (ISR) when […]

Resolving Device Not Found Error for PIR Sensor on ESP32 with Zephyr RTOS

Am working on a a home automation system that controls water pumps and taps based on motion detection using the Zephyr RTOS on an ESP32 microcontroller, how can i properly […]

Troubleshooting Relay Activation for Water Pump Control Based on PIR Sensor Detection on ESP32

Still based on my project on home automation system that controls water pumps and taps based on motion detection using the Zephyr RTOS on an ESP32. How can i properly […]

Resolving Deadlocks in ESP32 Robotic Arm Control with FreeRTOS

Hey guys i’m attempting on working on an ESP32 robotic arm control system using FreeRTOS and MQTT, but the system occasionally freezes. I suspect a deadlock between `controlArmTask` and `sendCommandTask`. […]

Handling Non-Atomic Operations for 64-bit Variables on a 32-bit Non-Preemptive System

Hi everyone, @Middleware & OS I’m struggling to find sufficient material on handling non-atomic operations, and I’d appreciate some guidance. I need to maintain a microsecond count in a 64-bit […]

what is the most accurate way in FreeRTOS to convert tick counts to milliseconds?

hey guys, I’m working on an embedded system running FreeRTOS on an ARM Cortex-M4 microcontroller clocked at 72MHz. I need to measure the execution time of a specific code block […]

Comparing ISR Handling in FreeRTOS, ChibiOS, and CooCox CoOS for ARM Cortex-M Projects?

Hey guys, I’m evaluating open-source RTOS options for an ARM Cortex-M project. While FreeRTOS, ChibiOS, and CooCox CoOS seem to offer similar features, I’m curious about real-world experiences. Specifically, how […]

Linux is now an RTOS

As of Linux 6.12 the real-time PREMPT_RT support has been merged into the kernel. It has only taken about 20 years! However, I still don’t want it controlling my car’s […]

Ensuring Message Prioritization on CAN Bus with AVR128DA48 and Zephyr OS for Industrial Monitoring

I’m trying to implement message prioritization on the CAN Bus for my Smart Industrial Monitoring System. High-priority messages (emergency alerts) should be transmitted before regular sensor data. I’m using the […]
