Today I tested a piece of code using a Renesas C019 microcontroller. I wanted to copy some data from the memory using memcpy(testbuf,(unsigned char *)0xFEF00,64); but the microcontroller was reset aft...
I designed an infrared adjustable clock, using external interrupt 1 as the pin of the infrared receiver and using the falling edge trigger mode. The program is in the attachment. After the program was...
I have just started learning FPGA and am planning to build a minimum FPGA system board. I would like to ask if anyone has any design guidance for the minimum FPGA system. I would be very grateful. If ...
——You only regret not having learned enough when you need it. Fortunately, I just reviewed some linear algebra recently, and I didn’t expect to use it in practice right away. I’m working on a project ...
Here are three commonly used components for mobile phone battery circuit protection. The batteries used in mobile phones are all lithium batteries, which may explode at high temperatures. In fact, it ...
After the system starts, copy a configuration file to the system through the synchronization tool, and then restart. The data obtained after the first restart is correct, and the configuration file ca...
1. Principle 1. Infrared emission protocol There are many infrared communication protocols. This experiment uses the NEC protocol. This protocol uses PWM modulation and uses pulse width to represen...[Details]
1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows: The output is as follows: It can...[Details]
Today, under the guidance of a low-level expert, I learned how to configure the PWM module! Woof! First open the file configured last time, as follows: Then, we need to use TIM1 to set PWM: Then,...[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]
After studying the F4 FSMC method to drive the touch screen for a few days, I have gained some understanding, which are listed below. The unorganized record is only for my own reference in the future...[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]

At the Boao Forum, Zhu Min, the current dean of the National Institute of Finance at Tsinghua University, said: "When talking about blockchain, we must first sep...[Details]
Unlike three years ago, today's
artificial intelligence
is no longer just a floating concept, and the venture capital circle has begun to explore the various possibilities of this technolog...[Details]
Superconductors have physical properties such as zero resistance effect, Meissner effect and Josephson effect, which make them have broad application prospects and unparalleled advantages in many b...[Details]
What is SYSTICK: This is a 24-bit system tick timer, SysTick, with automatic reload and overflow interrupt functions. All microcontrollers based on the Cortex_M3 processor can obtain a certain time ...[Details]
This paper proposes a design scheme for an embedded CNC system based on ARM and FPGA. The software and hardware design of the ARM system, the implementation method of hardware fine interpolation ...[Details]
