Programmer Group

2021 national college student electronic design competition question F intelligent drug delivery car Premise: This article focuses on sharing our own experiences and feelings and reflecting on our own shortcomings. The problem completion of our group is not very good. We solved the most important part, camera tracking and camera digital recogn ...

The foregoing: QQ: 961209458 V X: F9986858 Undertake graduation project. function 1. Use the 4 * 4 matrix key to enter the password 2. Passwords can be generated regularly and randomly 3. There is an external EEPROM that can store passwords to prevent power loss 4. Connect the mobile phone to Bluetooth and input specific instructions to obtai ...

1, Preliminary knowledge - program memory allocation The memory occupied by a program compiled by c/C + + is divided into the following parts 1. Stack - automatically allocated and released by the compiler to store the parameter values of functions, local variable values, etc. Its operation is similar to the stack in the data structure. 2. Hea ...

STM32 interrupt, DMA communication principle and programming method example STM32 interrupt, DMA communication principle and programming method example 1 Introduction to interrupt 1.1 concept Interrupt actually means that when the CPU executes a program, due to some random event (external or internal), the CPU temporarily interrupts the ...

Article content: One pin of the GPIOA end of the stm32F103 core board is connected to an LED, and one pin of the GPIOB port is connected to a switch (replaced by DuPont line simulation). Interrupt mode programming is adopted. When the switch is connected to high level, the LED lights up; When connected to low level, the LED is off. And use th ...

Interrupt knowledge point EXTI0 to EXTI15 are used for GPIO. Any GPIO can be used as the input source of EXTI through programming control. EXTI0 can be selected and configured as PA0, PB0, PC0, PD0, PE0, PF0, PG0, PH0 or PI0 through the EXTI0[3:0] bit of 1 (AFIO_EXTICR1) of AFIO's external interrupt configuration register. See figure. The ...

1, Stm32subemx interrupt mode LED on 1. Interruption and its function       It is precisely because of the interrupt mechanism that I can methodically "complete multiple tasks at the same time". The interrupt mechanism essentially helps me improve my concurrent "processing" ability. It can also bring the sa ...
