Building upon the basic single-conversion method, transitioning to continuous mode with interrupts unlocks a highly efficient, non-blocking approach to capturing analog data. This technique frees up the CPU to handle other critical tasks while...
READ MOREIn Part 1 of our BLE application development series for the STM32WB55! In this guide, we will explore the key features of the STM32WB55, introduce core Bluetooth Low Energy concepts, and configure a basic GPIO to blink an LED as our first step...
READ MOREThis guide demonstrates how to configure the STM32F4 Analog-to-Digital Converter (ADC) using the Low Layer (LL) drivers for a straightforward single-channel, single-conversion read. By bypassing the overhead of the Hardware Abstraction Layer...
READ MOREAdding fluid, dynamic animations to embedded displays doesn’t require a high-end GPU or a complex graphics framework. In this guide, you will learn how to use the U8g2 graphics library to build a zero-flicker, high-frame-rate audio...
READ MOREBuilding a professional embedded user interface doesn’t require an expensive color TFT. In this guide, you will learn how to use the U8g2 graphics library to craft a sleek, responsive dashboard with dynamic data and progress bars on a...
READ MOREThe INA219 is an I2C-based power monitoring module designed to measure high-side DC voltage, current, and power in real time. Interfacing this sensor with an STM32 microcontroller enables precise power tracking using standard HAL I2C drivers for...
READ MOREIn this fifth part of our STM32 Low-Layer (LL) I2C series, we complete our non-blocking driver suite by leveraging Direct Memory Access (DMA) for memory read operations. We will demonstrate how to configure the DMA controller and manage the I2C...
READ MOREWith the timer and GPIO successfully configured, we will now shift our focus to actively transmitting data. By leveraging the TIM3 interrupt, the microcontroller will autonomously shift bits out to the TX pin, ensuring precise baud rate...
READ MOREIn the fourth part of our STM32 Low-Layer (LL) I2C series, we offload transaction overhead from the CPU by implementing Direct Memory Access (DMA) for memory write operations. We will explore how to configure the DMA controller to automate byte...
READ MOREIn this new series guide, we shall emulate the UART hardware using a clever combination of timers and DMA to achieve effortless, CPU-independent serial communication. Before a single byte can take flight, we will use STM32CubeMX to forge the...
READ MOREIn this third installment of our STM32 Low-Layer (LL) I2C series, we shift from receiving data to actively configuring slave peripherals by updating the time registers on the DS3231 RTC. We will explore how to build a robust multi-byte write...
READ MOREEstablishing reliable bidirectional communication is the foundational step in validating the sensor emulation framework, ensuring that the master device and the emulated sensor can exchange data packets effectively. By implementing an echo...
