How can I accurately measure CPU usage for these ISRs while addressing nested interrupts?

I am using FreeRTOS on an STM32F4-Nucleo board and `vTaskGetRunTimeStats()` to measure task CPU usage with the following code: void configureTimerForRunTimeStats(void) { g_osRuntimeCounter = 0; } unsigned long getRunTimeCounterValue(void) { […]

Why Does Disabling OCIE1A Cause Immediate ISR Re-trigger on Mega 2560?

Hii guys 😌😌 I’m creating lighting variations on PORTA with a MEGA 2560 board. I am using a zero-cross detection that triggers an interrupt, which calls the “void passage_a_0” function. […]

Mongoose Ws implementation on STM32H753ZIT6 MII error

Hello everyone, I am trying to run Mongoose WS on my stm32h753zit6 board but every example they use NucleoH753ZI. They are using RMII mode but in my case I am […]

How to Manually Program an Interrupt Service Routine (ISR) for STM32F4 MCU Without Using Libraries?

Good day everyone, I have gone through the Datasheet and User Manual for my STM32F4 Microcontroller Unit (MCU) in great detail, including PM0214 for STM32F4xx MCUs. Additionally, I have searched […]

Debugging Issue with OpenOCD on STM32F411 in CLion

I’m using CLion (version X.X) for embedded development on an STM32F411 microcontroller with OpenOCD 0.11.0. While ‘build’ completes, the debugger fails with the following error: Error executing event examine-end on […]

Trouble Generating PWM Signal on STM32 NUCLEO-F207ZG Using Low-Level Register Programming

I’m programming an STM32 NUCLEO-F207ZG board and trying to output a PWM signal on pin PE_9 (D6) to drive an LED. I’m using low-level register programming (no HAL/LL drivers). However, […]

STM32WB15CC Custom BLE Project Not Discoverable – Missing Configuration?

I am new to STM32WB15CC and am using the STM32WB15CC NUCLEO board. I successfully ran the BLE example `p2pserver` on my board, where the device is discoverable, and I can […]
