Given a BRCLK clock source, the baud rate is used to determine the factor N that needs to be divided:N = fBRCLK/BaudrateThe division factor N is usually a non-integer value, so at least one divider an...
This is a document from a Freescale engineer, which compares the Freescale coldfire v1 core MCU with the hot ARM cortex m3 through experiments. It can be seen that coldfire v1, as the lowest-end archi...
I have an MFC program. The Release version needs to reference a C LIB library called Encryption InitInstance(). When it is initialized, only one function of this library is called (and this library on...

For STM32, there are two ways to reset the software: 1) Use the official software library The system reset function is directly provided in the stm32f10x_nvic.c file of the official software li...[Details]
Using Systick timer to achieve delay 1. SysTick timer characteristics The SysTick timer is a 24-bit down counter, that is, when vlue is decremented to 0, an interrupt is triggered and the load va...[Details]
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[Details]
The trade war between China and the United States has become the focus. The United States has begun to play the ban card against Chinese technology companies. The ZTE incident shows that if the ban...[Details]
Friends who work in the photovoltaic industry, do you still remember the hard work on June 30 last year? How many people worked late into the night for months in a row just to connect to the grid a...[Details]
I used STM32CubeMX V4.22.1 to generate a project including EHT and Lwip. The debugging has been abnormal. After careful inspection, the following problems were found: 1. The hardware uses LAN8720A, b...[Details]
Since China began to try to produce panels independently in 1998, in 2018, China's panel industry has gradually upgraded from a marginal industry to the largest production scale. Especially in the ...[Details]
I rewrote the main part of this program. The program uses the watchdog as a normal timer and scans the digital tubes in the watchdog interrupt. In addition, I added a display buffer. If you want to d...[Details]
STM32 uses FSMC to read and write CPLD programs. CPLD is hung on the address line and data line of STM32. CPLD is regarded as an off-chip RAM for reading and writing. On the board I made, CPLD is hun...[Details]
