IoT Technology Practical Tutorial Based on Bluetooth 4_Edited by Mao Jianfei and Zhou Xue
I bought this book and read the peripheral routines in TI's SDK, which said that feature 1 and feature 3 are u...
As shown in the figure below, J1 and J2 are required to be 5V input and J3 is required to be 5V output. When J1 inputs 5V, Q1 and Q2 are turned on and J3 outputs 5V; when J2 inputs 5V, Q3 and Q4 are t...
I use STM32F103VCT6 to drive T6963C and it can display.But it will not display after power off and back on, it must be re-burned before it can display.
I deliberately added a flashing light program in...

1. Purpose In actual product release, if the program stored in the MCU Flash is not protected, some illegal companies may read the program in the Flash through an emulator (J-Link, ST-Link, e...[Details]
In the actual project development process, hardware circuits often need to be modified, and the modified parts need to modify the driver. Thinking about the coming and going of such requirements is t...[Details]
The program got stuck during LCD initialization. Through hardware debugging, it was found that it was stuck in the Delay_ms() function. Going to the definition, it was found to be a macro definition ...[Details]
1. Usage scenarios In the first case, when using a common STM32 delay function, similar to HAL_Delay(time), since this function uses a loop to judge and delay, when executing this function, the ent...[Details]
Because the STM32 HAL library only has millisecond-level delay for HAl_Delay(), in order to achieve accurate microsecond-level delay, Systick has to be modified. However, since it is used internally ...[Details]
From last year to now, competition in the photovoltaic inverter industry has become increasingly fierce. In addition to the introduction of new products, various marketing and promotion methods hav...[Details]
Nowadays, everyone is saying that "technology is people-oriented". The essence of the development of technology is to serve the improvement of the quality of life of human beings. Automated driving...[Details]

In 1949, after three years of civil war, the Nationalist government was defeated and retreated to Taiwan. The political and academic circles launched a large-scale reflection on why they failed in ...[Details]
Use the STM32 timer input capture module to control 3-way ultrasonic sensors. The ultrasonic sensor used this time is the common HC-SR04, which is often used in the obstacle avoidance system of smal...[Details]
Note: This STM32 microcontroller is the STM32F103 series. The ADC of Stm32 has DMA function. This is beyond doubt and is what we use most! However, if we want to sample a signal (such as a pulse sign...[Details]
The code for using timer 0 to implement a running light in a 51 MCU is as follows. The LED light is connected to port P1. The code is annotated below, so I won't explain it in detail. My English is n...[Details]
It is required to use MCS-51 microcontroller to sort data. 1. Sort the 8 data in ascending order; 2. The data to be sorted is stored in the internal data memory address units 30H-37H, which are 34H, ...[Details]
