stm32f1

Usually used in the serial port and SPI configuration listed here, so that a contingency, directly brought over to use. It also points out the frequent problems of STM32F1 series and STM32F2 series. The library function used is the standard library function, not the HAL Library. First, the configuration of the serial port:STM32F1 Series Serial Port: * * Function Name: usart1_config () * Description: Serial 1 configuration function * Input: no * output

ObjectiveSTM32F1 Series Chip is considered as the first series in STM32, which is widely used in real life. Therefore, a summary of the STM32F1 series chip common on-chip resources, each article will focus on the presentation, and provide software source code engineering.Summarize common resources: Basic IO, timer Tim, serial Usart, ADC analog-to-digital conversion, DAC digital-to-analog conversion, SPI serial communication, exit external interrupt, B

latest UCOS2.92. Transplant good, independent 4 projects for everyone to download learning, research. Set up the task is the same, only for the chip, the ports directory under the relevant source code is different, the standard peripheral library also has differences. Each series for different types of chips just need to change the "model" on the line.Software engineering that provides downloads is run on the board, ensuring that no problems are uploaded to the 360 cloud disk.Ucos based on STM3

ObjectiveAs St company launched more than STM32F1 cost-effective F0 chip, now on the market F0 chip share is very high. F0 chip belongs to M0 core, the main frequency 48M (of course, can overclock, but try not to exceed too much), the resource size can be selected according to the project needs. So, in recent days, summarize the knowledge about STM32F0 development.This article mainly stm32f0, mdk-arm to explain the "new software engineering detailed p

0x1d, followed by r/w bits. This translates to 0x3a write, 0x3b read. With the ALT address PIN (PIN 12) grounded, you can select the alternate i²c addresses 0x53 (then the r/w bit). This translates to 0xa6 write, 0xa7 read.Since the ALT address pin (PIN 12) is grounded in the Kylin seat, the addresses are 0x53, which is 0xa6 write, 0xa7 read. In addition, 2 terminal signals are also introduced into the MCU.3 , Software designThen we started the software design. Since the ADXL345 uses the I²c in

camera and the main control Panel selection 工欲善其事 its prerequisite, a good camera can bring a huge advantage to the game even the unexpected super buff, or even directly determine whether your game is a country or a reactive return. There were a variety of cameras at the time, and we could be broadly divided into three categories: 1. Fire, Mountain, Lanzeo and other Smart car store hardware two-value camera 2. The camera of the ov2640 and other ov7725 ov7060 to output images in RGB565 format. 3

Change the ad conversion value and voltage value by adjusting the potentiometer stm32f1 ADC Configuration steps 1. Enable Gpio clock and ADC clock2. Configure PIN mode for analog input3. Configure the ADC's divide factor4. Initialize the ADC parameters, Adc_inittypedef5. Enable ADC6. Perform ADC calibration7. Set the ADC software to start8. Read ADC conversion values9. Set ADC rules, sampling time, etc.10. Convert software to enable ADC11. Read ADC Co

PrefaceThis article explains how to set the interrupt priority for the STM32 cortex M3 and M4 series MCU in the FreeRTOS embedded operating system. Summary"1" STM32L1 series, STM32F1 series, STM32F4 series, set NVIC need to use Nvic_prioritygroup_4. The "2" preemption priority is larger than "MAX" and smaller than "LOWEST". such as Configlibrary_max_syscall_interrupt_priority=5 configlibrary_lowest_interrupt_priority=15 The specific value of the Nvic

the aluminum frame, all parts can be disassembled. After the mechanical structure is done, there is one day left to write the program, and it feels like most of the time the game is in the design of mechanical structure. But this is very necessary, because if the mechanical structure is not good, your program optimization of the better, it will not be stable, especially such a large device. a bunch of crap is in front of you, and here's a little bit of something useful:① we choose the controlle

1, what is the STM32 function libraryThe above mentioned software library refers to "STM32 standard function library", it is provided by St Company for STM32 function interface, namely API (application program Interface), developers can call these function interfaces to configure the STM32 register, Enables developers to disengage from the lowest register operation;In fact, the library is the code that is erected between the register and the user-driven layer, processing the configuration direct
