Basic Overview:
The 874003BG-05LF-HT is a microcontroller with integrated peripherals, including GPIO (General Purpose Input/Output) pins, analog-to-digital converters (ADCs), timers, and communication interfaces such as UART (Universal Asynchronous Receiver-Transmitter) and SPI (Serial Peripheral Interface). It operates on low power and can be programmed using various development environments and programming languages.
Application in Simple Projects:
To demonstrate the capabilities of 874003BG-05LF-HT, let's consider a basic project: LED Blinking.
Experiment Steps:
1. Hardware Setup:
Connect an LED and a current-limiting resistor to one of the GPIO pins of 874003BG-05LF-HT, such as pin PA0. Ensure proper polarity of the LED.
2. Software Setup:
Choose a development environment for programming the 874003BG-05LF-HT, such as Arduino IDE or STM32CubeIDE. Set up the environment and create a new project for the microcontroller.
3. Coding:
Write a simple program to blink the LED connected to the GPIO pin. This can be achieved by toggling the pin state between high and low at specific time intervals using software delays or hardware timers.
Here's a basic example using C language and STM32CubeIDE:
#include "stm32f0xx_hal.h"
void SystemClock_Config(void);
int main(void)
{
HAL_Init();
SystemClock_Config();
// Initialize GPIO pin for LED
GPIO_InitTypeDef GPIO_InitStruct = {0};
GPIO_InitStruct.Pin = GPIO_PIN_0;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
while (1)
{
// Toggle LED state
HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_0);
scss
Copy code
// Delay
HAL_Delay(1000); // 1 second delay
}
}
void SystemClock_Config(void)
{
RCC_OscInitTypeDef RCC_OscInitStruct = {0};
RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};
RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;
RCC_OscInitStruct.HSIState = RCC_HSI_ON;
RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;
RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE;
if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
{
Error_Handler();
}
RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK | RCC_CLOCKTYPE_SYSCLK | RCC_CLOCKTYPE_PCLK1 | RCC_CLOCKTYPE_PCLK2;
RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_HSI;
RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV1;
RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;
if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_0) != HAL_OK)
{
Error_Handler();
}
/ Configure the Systick interrupt time */
HAL_SYSTICK_Config(HAL_RCC_GetHCLKFreq() / 1000);
/ Configure the Systick */
HAL_SYSTICK_CLKSourceConfig(SYSTICK_CLKSOURCE_HCLK);
/* SysTick_IRQn interrupt configuration */
HAL_NVIC_SetPriority(SysTick_IRQn, 0, 0);
}
4. Build and Flash:
Compile the code and flash it onto the 874003BG-05LF-HT microcontroller board using a compatible programmer or debugger.
5. Observation:
Once the code is flashed successfully, observe the LED connected to the GPIO pin. It should blink at intervals of one second.
Conclusion:
In this experiment, we utilized the 874003BG-05LF-HT microcontroller to control an LED, demonstrating its basic GPIO functionality. This project serves as a foundation for more complex projects involving sensors, actuators, and communication interfaces.
