[STM32 motor square wave] Record 2——NVIC interrupt basic settings

NVIC concept: provides an interrupt controller for overall management of exceptions, called "embedded vectored interrupt controller". In simple terms, it is a module that provides and handles internal interrupts of the MCU. NVIC library functions: Interrupt Priority: Before configuring NVIC, you need to understand

STM32 study notes - using the general timer TIM2 for precise delay

1. General timer overview and performance 1.1 Overview On the stm32 chip used by the author, there is a total of 1 advanced timer TIM1 and 3 general timers TIM2, TIM3, and TIM4. Each general timer consists of a 16-bit auto-load counter driven by a programmable prescaler. It is suitable for a variety of occasions,

STM32 serial port circular queue data processing case

1. Structure typedef struct { u8 data ; //queue storage area u8 front; //dequeue mark u8 rear; //entry mark }sequeue_t; 2. Create a queue sequeue_t * create_empty_sequeue() { sequeue_t * sq; sq = (sequeue_t *)malloc(sizeof(sequeue_t)); sq- front = sq- rear = 0; return sq; } 3. Determine

STM32 online upgrade summary

1. The function implemented in the first two blogs is to jump between APP and IAP; Second, there are the following points that need attention; 1. Remember not to write the program jump function in the timer interrupt, otherwise the program can jump normally but the interrupt function cannot be executed. For the reason

STM32 serial port multi-machine communication

The slave devices are cascaded in open-drain mode. The serial port TX of the slave device must be configured as open-drain mode, not push-pull mode. If configured as push-pull mode, it will cause excessive current and the low level will not be able to go down. The STM32 UART data register is 9 bits, and data trans

The difference between STM32 and ordinary ARM

ARM is a British chip design company. Its most successful product is the 32-bit embedded CPU core ---- ARM series. The most commonly used ones are ARM7 and ARM9. ARM mainly provides IP core, which is the core structure of CPU. It only includes the most core part, not the complete processor. ARM sells this core to majo

STM32 ADC

How many bits does the ADC have? 12-bit How many ADCs are there? 1, 2 or up to 3, depending on the device; each with multiple channels. About the channel: 10.3.3 Channel Selection There are 16 multiplexed channels. Conversions can be divided into two groups: regular and injected. A serie
