In this first article of the STM company stm32f4-Discovery kit will talk about 2 16 character LCD applications. As a reminder on short kit 168 MHz ARM Cortex-M4 based microcontroller's. ingbank Program using Keil wrote. Keil is the reason I prefer not to have had the support of many libraries.
First, we create a new project file in Keil. How to follow a path before creating our project I'm talkin 'about me. Now we each code and write more complex programs do not have to bother to write it ourselves. Therefore, in my next article I will intend to use cmsıs effectively. Let's get into a little detail for the layman, what is this CMSIS? Cortex Microcontroller Software Interface Standard, ie a software standard ingbank developed for Cortex microcontrollers. So what we need to understand. CMSIS is not dependent ingbank products (ie can be used no matter which manufacturer) ingbank hardware abstraction layer for the Cortex-M processor series is. As seen in the figure below we will write our application ingbank software and the hardware of the standard. cmsıs CMSIS Core components (that we will use in this application) CMSIS CMSIS-DSP RTOS API to CMSI CMSIS-SVD-DAP
CMSIS Corea, the basis for Cortex-M devices and programmers to create a runtime system kernel and device gives access to peripherals. In order to use CMSIS-Core is imperative that these files are added to your project: Startup file: StartUp_Dir ingbank <device>. SYSTEM_A <device> s System configuration files. ingbank C and <device> SYSTEM_A. H header file <device.h> Devices
<device> StartUp_Dir. works after a reset of the device s files and then calls the function systemınit. systemınit, SYSTEM_A <device>. c file's ready. According to this function may change the values in the application. after systemınit main function is executed. At the same time provides vectorine interrupt ingbank the startup file.
cmsıs us to use our programs is very convenient when writing. How is that? Here hereinafter Let's continue to build the project and how it would benefit us to use it, let's see together.
Project-> New Project UVision call, open the window, select the location that we will register our project after project ingbank Create a new project by typing the name. STM32F407VG the bottom of the screen that appears later + STMicroelectronics integrated call and press OK. In the following window pops up later. (You can not get the library until the following pop-up window at the end, see the NOTE-1)
In this window manager ingbank seems to work environment. So when running our program we want to add libraries, etc. of the combined required. management screen. From where ever you choose something that is required if we create our project we have to do everything ourselves. We need to add the file to your project folder startup_stm32f400xx.s also systemınit our main.c file () function, we need to write ourselves. If they want to use any other peripherals you need to add them ourselves.
Anyway, ingbank the above screen you want to add the startup file and would choose him. Just because we chose the startup, a warning is displayed as follows: "require CMSIS Core", those of us also need to add CMSIS core, he says.
I put the images folder individually. The leftmost image files in the project folder is located and RTA. The rightmost file, select it from the work environment that we manage the startup file is located. Our project will add an main.c file. For this Keil Located on the left side of the Project window, right-click Source Add New Item Group 1 to Group 'Source Group 1' ... We choose C from the pop-up window, select ingbank a file named main.c we create our file.
Template tab in the lower left corner of the screen above, select your file, you can add ready-made templates. My advice to you from Head geitir template and add a habit of adding to the program not only fill her
Device reset after our program will run at the startup_stm32f40xx.s file is located. ingbank This file is a file written in assembly language. system_stm32f40xx.c file systemınit () and systemcoreclockupdat ingbank () function that includes the c file. Normally we have to write our program in systemınit ingbank () function is located here in a ready manner. If you want to make additions to this function, you can make changes to the clock settings. Already this file you copied to your project subfolder
