1 overview of external interrupts          EXTI (External interrupt/event controller) - External interrupt/event controller, which is different from the external interrupt of CM3 kernel described in STM32NVIC interrupt priority management (interrupt vector table). Specifically, the external interrupt of ...

(1) MSP432 serial port introduction    MSP432P401R does not have a special serial port device. To use the EUSC module to configure UART mode, serial port communication is very convenient and easy to use. It is the most common interface in embedded devices. Here, we configure the serial port of MSP432 to 8in1 mode, 8-bit data, 1-bit s ...

    speaking of printf() function, students who write code must be very familiar with it. This is a standard printing function in C language, which is often used when debugging code or information output. The conversion of printf function is described as follows: Conversion description modifier Tags in printf() The following ...

1, Introduction to experiment A small experiment made by personal learning. The function is to use the voice and infrared functions of one board to control the LED light on and off and buzzer response of another board. 2, Modules used 1. Two stm32f4 series boards 2. One ld3320 speech recognition module 3. 2 infrared transceiver modules (wi ...

serial communication Serial port Serial interface is abbreviated as serial port, also known as serial communication interface or serial communication interface (usually COM interface), which is an extended interface using serial communication mode. Serial interface refers to the sequential transmission of data bit by bit. Its characteris ...

1. Introduction to interruption The code is mainly distributed in the firmware library stm32f10x_exti.h and stm32f10x_exti.c File. Here we first STM32 IO Some basic concepts of port interrupt. STM32 Each of IO Can be used as an external interrupt Interrupt input port, which is also true STM32 The power of. ...

Note: the model of this single chip microcomputer is STC15F2K60S2 principle As shown in the figure, light emitting diodes L1-L8 are in common positive connection, and VCC is the positive pole of power supply, with high level. It is known that the LED is on in the forward direction and off in the reverse direction. In order to make the diode l ...
