We will set up a code in which STM32 Blue Pill will echo back the received bytes to the sender using UART RX interrupt. The code will echo back whatever it will receive on the Rx pin to the terminal. In other words, whatever you type on the serial terminal, it will be sent to the...
The code example for IWDG and the setup for it is very simple. A LED connected to PC 9 remains off until a push button connected to PA9 is pressed. This indicates initialization stage. Once pressed and held, the LED starts blinking, indicating normal operation. When the button is released...

/* Configure User push-button in Interrupt mode */ BSP_PB_Init(BUTTON_KEY, BUTTON_MODE_EXTI); /* Wait for User push-button press before starting the Communication. In the meantime, LED1 is blinking */ printf("hello"); while(UserButtonStatus == 0) ...
所有端口都具有外部中断功能。要使用外部中断线,必须将端口配置为输入模式。具体参考Example详细介绍1. GPIOx_MODER(GPIO 端口模式寄存器)2. GPIOx_OTYPER(GPIO 端口输出类型寄存器)3. GPIOx_OSPEEDR(GPIO 端口输出速度寄存器)4. GPIOx_PUPDR(GPIO 端口上拉/下拉寄存器)...

Interrupts Some interrupts are managed in this application example as described below: • Systick_Handler(): Based on the system tick timer, this 1ms interrupt manages the delays used by the software. • EXTI0_IRQHandler(): This interrupt detects any activity p...
1.1 STM32 QVGA TFT-LCD direct drive principle Controller-less TFT-LCD panels have different data-line configurations, for example 16-bit, 18-bit or 24-bit RGB lines. A TFT-LCD with a 16-bit data interface offers 565 format for each pixel. The TFT-LCD ...
