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 […]

Understanding cmp Instruction in Assembly and Debugging with GDB

I’ve come across a specific instruction sequence that I need help understanding, particularly the comparison (`cmp`) operation and how to break at this point in GDB on an Intel Core […]

Improving Stability of Pitch and Roll Measurements in MPU6050 Flight Controller

Hello guys, I’m working on a flight controller using an mpu6050 and I’m wondering if the pitch and roll fluctuate too much. These values represent the output of a complementary […]

Optimizing 8-bit Parallel RGB Interface on Nucleo-F411RE: Timer Interrupts or DMA?

I’m working on a project to control a display using an 8-bit parallel RGB interface with the Nucleo-F411RE, requiring a 1 MHz PCLK. Since the STM32F411RE lacks LTDC peripherals, I […]

Understanding UART Overrun Error When Sending AT Commands from STM32 to ESP8266

I’m interfacing an ESP8266 with an NUCLEO-L073RZ using UART1 `PA9`, `PA10` for communication with the ESP and UART2 for communication with a PC for debugging. I also used a CP2102 […]

Issue with Command Handling in AVR128DA48 UART Communication

I am using AVR128DA48 microcontroller to control an LED in serial communication. The way I set it up is not complex; I’m sending *‘ON’* and *‘OFF’* commands from a `python` […]

No Pulse Detected Error in ESP32 Heart Rate Monitor with MAX30102

I am designing a heart rate monitor system using an `ESP32` microcontroller, tested on a `breadboard setup`, to simulate the functioning of a `pacemaker`. The system continuously monitors `heart rate` […]

Issues with I2C Communication to VL53L0X Sensor Using STM32F103C8 Without ST Library

I am using the VL53L0X sensor with an STM32F103C8 microcontroller and want to communicate with the sensor directly over I2C without using ST’s library. My goal is to minimize project […]
