AN5062-STM32F0DISCOVERY peripheral firmware examples.pdf

March 2013 DocID022897 Rev 3 1/17 AN4062 Application note STM32F0DISCOVERY peripheral firmware examples Introduction This application note describes the peripheral firmware examples provided for the STM32F0DISCOVERY Kit. These ready-to-run examples are provided to help the user get started quickly with STM32F0xx peripherals and STM32F0DISCOVERY board hardware. Preconfigured projects for EWARM (IAR Embedded Workbench? for ARM?), MDK-ARM?, Atollic TrueSTUDIO? and Altium TASKING? toolchains are provided for each example. These examples are included in the firmware applications package available for download on /stm32f0discovery. Users are advised to first read the document Getting started with software and firmware environments for the STM32F0DISCOVERY Kit (UM1523) to familiarize themselves with the STM32F0DISCOVERY Kit. Table 1 lists the microcontrollers and development tools concerned by this application note. Table 1.
