How to Fix CR/LF Transmission Issues Between MS Excel VBA and STM32 via Serial?

I am trying to exchange data between MS Excel (using VBA) and my STM32 Nucleo board via a serial line (virtual COM port). I am using the Microsoft Datastream add-in, […]

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) { […]

Is the Built-In TCP/IP Stack in GPRS Modules Redundant for Embedded Linux, or Are There Benefits?

Good day everyone, I’m exploring GPRS modules for embedded Linux. Many vendors offer modules with built-in TCP/IP stacks. Since embedded Linux usually has its own TCP/IP stack and uses PPP […]

facing issues reading data from the SIM800 module

Good day devs, I tried integrating a SIM800 module with FreeRTOS for a small start up. I plan to use HAL_UART functions with a timeout mechanism for UART communication, but […]

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 […]

Issues with Viewing PRINTF Output on STM32 Nucleo L476RG with X-Nucleo IDB05A1

I’m working with the STM32 Nucleo L476RG board and the X-Nucleo IDB05A1 expansion board to develop Bluetooth Low Energy applications. My development environment is Keil uVision5, and I’ve successfully built […]
