STM32F3 Discovery board is a great device for studying robotics and mobile automotive tools. It contains fast MCU Cortex-M4 @ 72MHz, 40+8 kB RAM, 256 kB Flash, dozens of I/O ports for peripheral units, built-in gyroscope and accelerometer, on-board ST-LINK/V2 for programming and debugging. This board is good enough to develop a flight. The upper part is the configuration of SDRAM control: 1. So we use SDRAM bank1 (this BANK is not another BANK, it is BANK1 of STM32) 2.

It consists of 10 pins. We will be using pin2 SWDIO, pin6 SWCLK, pin4 GND, and pin8 3.3V to connect with our STM32 board. The SWDIO is the data input/output pin and the SWCLK is the clock pin. Follow the pin configuration given on the ST-LINK V2 to identify each pin. 1. You set the GPIOs' speed to 100 MHz; this is the speed limit the hardware can support. But the final data exchange speed may also be limited by how fast your code can run, because the data clock, etc. is driven by your code now. In my opinion, not all STM32 family members support the 100 MHz GPIO speed, and some family's MCU speed is lower. Clock Setting Procedure. ① RCC System reset. First, reset the microcontroller clock system by executing RCC_DeInit (). Immediately after power-on, the clock system is in its initial state (Internal HSI: 8 MHz), so this function does not need to be executed, but it is executed for fail-safe reasons. 2. The lower part is the configuration of SDRAM timing in memory clock cycles (the following units are SDRAM clock cycles, which can be filled in according to the values in the device manual, because the SDRAM timing configuration function of HAL library will assign the value of -. Once the clock speed is set up, it is a good idea to store the current system clock frequency in a global variable; I'll use a uint32_t core_clock_hz in this tutorial. Using a Timer Peripheral With the core system clock set to a known frequency, we can use the chip's built-in "timer" peripherals to trigger actions at fairly precise. SW[1:0] is used to set the system clock. Since I am using the PLL_P as the system clock, I will write a 2 (1:0) to the SW Bits; SWS[3:2] is used to monitor the status of the system clock. So here we will wait for these bits to indicate that the PLL_P has been set as the system clock (wait for the SWS bits to indicate 2 (1:0)). HSE configuration.The XPD library requires precompile time information about the system clock sources for correct operation. Therefore the HSE API is only available when the HSE_VALUE_Hz is defined as the nominal frequency of the input clock in Hz. Two types of external clock sources can be handled by the STM32 devices:. Open STM32CubeIDE, start a new project, select your board (Nucleo-L476RG. In this tutorial, we'll be discussing the STM32 timers modules in STM32 microcontrollers. There are different hardware timers in STM32 microcontrollers each can operate in multiple modes and perform so many tasks. You'll get to know these different hardware variants and their application use cases. Abstract and Figures.
