Let's choose the internal RF oscillator as the reference for this project and leave everything else as default. The clock system supports 4 types of clock generator.Īn external low-frequency oscillator, which, unfortunately, is not soldered on the debug board, an internal 40 kHz low-frequency oscillator, an 8 MHz internal high-frequency oscillator and an external high-frequency oscillator.
Let's leave everything as default for the first project and go to the next tab - clock configuration– clock configuration. The power of the microcontroller is supplied to the VDD (high level) and VSS (low level) pins and is standardly from 2 to 3.6 V. For the selected STM32F3Discovery board, we have already marked the I / O lines used for the LEDs, for the button, and for other peripheral modules that are routed on the board. The left side lists all peripheral modules that can be used in this microcontroller. The project window opens, where on the right side we see the microcontroller with all its outputs. The microcontroller series can be selected according to the microcontroller type. In the future, I will show how to work directly with the microcontroller installed on it.Ĭhoose Board Selector ST Microelectronics, board type - Discovery. Let's create the first project for the debug board. In the window that appears, we can select the type of microcontroller. Launch STM32CubeMX and select New Project.
But TIM2_IRQHandler is never called - it even gets optimized from the C-compiler (so in dissasembly there is no TIM2_IRQHandler anymore).In this lesson, we will create the first project for STM32. I am using IAR Embedded Workbench for ARM v8.22.2 (so latest version). * Set GPIO C13 as High-Speed PushPull output */ RCC->CFGR = RCC_CFGR_SW_1 | RCC_CFGR_PLLMULL_3 | RCC_CFGR_PLLMULL_2 | RCC_CFGR_PLLMULL_0 * Set System-Clock as high as possible */ * IRQ definitions in CMSIS startup_stm32f10x */ I tried to create an Interrupt Service Routine for the Timer2 Overflow Interrupt like this: #include "stm32f10x.h"
