Taking data acquisition to the ultimate level of efficiency, this guide explores using Direct Memory Access (DMA) to capture continuous single-channel ADC conversions on the STM32F4. By configuring the DMA controller alongside the LL drivers, the...

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...

This 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...

In 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...

In 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...
