From: STM32 external interrupt experiment - EXTI Author: three speed sub20 Released on: October 19, 2020 13:51:42 website: https://blog.csdn.net/weixin_44234294/article/details/109154934 Introduction to STM32 external interrupt Each IO of STM32 can be used as an external interrupt Interrupt input port, which is also the strengt ...

1, Experimental principle Analysis: the clock is 84Mhz, the frequency is 84, the ARR is set to 500, the clock obtained by the counter is 84M/84=1 Mhz, and the counting time is 0.5ms In the main function, the modification time I set is 2ms once. As shown in the figure, set PWM1 mode, and the output polarity low level is valid. That is, when t ...

brief introduction The main purpose of this paper is to establish the communication connection between STM32 and Dynamixel steering gear, develop the control framework of upper computer lower computer steering gear, issue instructions in the upper computer, the lower computer executes the outer loop of steering gear force control, and the stee ...

preface This program design is based on embedded development board CT117E,stm32f103RBT6. If you don't understand the code of which module, you can click my blog to see the writing ideas of each module. 1, Test questions 2, Modules needed 1.LED The code is as follows: LED c: #include "led.h" void led_init(void) { GPIO_ ...

The project needs to add a card reader device without transplanting USB routines. An external chip (CH9350) is directly used, which is very stable without driving;I only use one of the functions of this chip: the conversion of HID data from USB to serial port data, the lower computer mode used, and many other functions. See the manual for detai ...

summary: CMake is a more advanced compilation and configuration tool than make. It can generate corresponding Makefile or vcproj projects according to different platforms and compilers. By writing cmakelists Txt, you can control the generated Makefile to control the compilation process. We often use the Makefile automatically generated by CMa ...
