[Revised] Emulating UART Part 2: Sending Data
In Part 1 we configured the timer and the transmit pin; in Part 2 we put that time base to work and actually send…
Getting Started with STM32 Low Layer (LL): Analog to Digital Converter Multi Channel Continuous Conversion with DMA
Expanding upon our single-channel DMA foundation, this guide scales the STM32F4’s ADC to simultaneously sample multiple analog channels. By enabling the ADC’s scan mode…
Getting Started with STM32 Low Layer (LL): Analog to Digital Converter Single Channel Continuous Conversion with DMA
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…
Getting Started with STM32 Low Layer (LL): Inter-Integrated Circuit (I2C) Read From Registers Using DMA
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…
Getting Started with STM32 Low Layer (LL): Inter-Integrated Circuit (I2C) Write to Registers Using DMA
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)…
Getting Started with STM32 Low Layer (LL): UART Reception using DMA
Eliminate the CPU overhead of processing individual incoming characters by offloading variable-length UART reception entirely to the DMA controller. By pairing a circular or…
Getting Started with STM32 Low Layer (LL): UART Transmit Using DMA
Achieve the absolute pinnacle of microcontroller efficiency by offloading the entire UART communication workload from the CPU to the Direct Memory Access (DMA) controller. This guide…
STM32F407 Discovery Audio: Transmitting I2S Data using DMA
Building upon the fundamentals of polling mode, this next section transitions to using Direct Memory Access (DMA) to handle the data stream. By offloading…
STM32 UART Part 7: 1- Wire Protocol Receiving Data
In this part, we dive into how the STM32 receives data from a 1-Wire sensor, interpreting the precise timing signals that represent logical bits. Understanding…
