Your board should be flashing all the 4 LEDs at 500msec interval. You should see messages with no errors in the Build Output window again. From the 'Flash' menu click on 'Download' button or use hotkey 'F8' or click on the Download button in the toolbar as shown below. For now you can ignore the warning appearing about padding.ĭownload code to the board. there is only information about RCSYS but suppose, that is different timer Quite definitely a different timer. Simply Googling Cortex Systick timer will overwhelm you with information. You should see the build messages with no errors in the 'Build Output' window. in datasheet is not any information about SysTick timer, You need to be looking in the ARM Cortex-M datasheet there is a lot of information. From the 'Project' menu click on 'Build' or use hotkey 'F7' or click on the Build button in toolbar as shown below. Make sure you connect the USB cable to the ST-Link debugger (circled in the below image).īuild the project. In particular the STM32F40x Reference manual, STM32F407 Datasheet, STM32F4-Discovery user manual and ARM Cortex-M4 generic user guide come handy to understand and write assembly code.Ĭonnect the STM32F4 Discovery board to your PC. The 'Books' tab shows useful documents and resources. From the 'Project' menu click on 'Open Project' and select the project file mdk-arm/stm32f4-discovery-blink.uvprojx If you already have Keil MDK-ARM and STM32F4 software pack installed then you can skip directly to step 3.

Head to and locate the ST Microelectronics STM32F4 Series Device Support Drivers and Examples. In absence of the board you can also use the Keil simulator and watch the registers but that part is not covered here.ĭownload and install Keil MDK Lite Edition from Keil website - /demo/eval/arm.htm#DOWNLOADĪfter installation of the IDE, you need to install the software packs for ST Micro devices. Get hold of a STM32F4 Discovery board so you can see the LEDs blinking. This README contains instructions to build and download the code to STM32F4 discovery board. The project files (for Keil uVision IDE) are in the mdk-arm folder. Source code is contained in this repository in the src.

This code uses ARM assembler and not the GNU assembler. Basic CMSIS Example is a simple example that shows the usage of the CMSIS layer. Thereafter, the functions described under Reference can be used in the application. It uses the SysTick timer provided in ARM Cortex-M core.įor detailed explanation of the code, refer blog post - The silicon vendors create these device-specific CMSIS-Core (Cortex-M) files based on CMSIS-Core Device Templates provide by Arm. This repository contains code written in ARM (V7-M) assembly to blink LEDs on the STM32F4 discovery board.
