## Contents What's New in AN2548 "Using the STM32F101xx and STM32F103xx DMA controller" V2.0.0 What is AN2548 "Using the STM32F101xx and STM32F103xx DMA controller"? AN2548 "Using the STM32F101xx and STM32F103xx DMA controller" update History License ## What's New in AN2548 "Using the STM32F101xx and STM32F103xx DMA controller" V2.0.0? The AN2548 "Using the STM32F101xx and STM32F103xx DMA controller" V2.0.0 is an update of V1.0.0 that makes the application note compliant with the Cortex™ microcontroller software interface standard (CMSIS). ## What is AN2548 "Using the STM32F101xx and STM32F103xx DMA controller" V2.0.0"? The AN2548 "Using the STM32F101xx and STM32F103xx DMA controller" describes how to use the STM32F101xx and STM32F103xx direct memory access (DMA) controller. The STM32F101xx and STM32F103xx DMA controller, the Cortex™-M3 core, the advanced microcontroller bus architecture (AMBA) bus and the memory system contribute to provide a high data bandwidth and to develop very-low latency response time software. This application note also describes how to take full advantage of these features and ensure correct response times for different peripherals and subsystems. The AN2548 "Using the STM32F101xx and STM32F103xx DMA controller" is full CMSIS compliant. ## AN2548 "Using the STM32F101xx and STM32F103xx DMA controller" V2.0.0 update History ### V2.0.0 - 04/27/2009 AN2548 "Using the STM32F101xx and STM32F103xx DMA controller" V2.0.0 updated with STM32F10x Standard Peripherals Library (StdPeriph_Lib) V3.0.0. AN2548 "Using the STM32F101xx and STM32F103xx DMA controller" V2.0.0 is full CMSIS compliant STM32F10x Standard Peripherals Library Structure is updated.
