[size=12px][table=98%] [tr][td]I've recently been using the RT9818C reset chip. When testing the waveform, in the power-off state, there will be a short period of non-zero level on RST (as shown in th...
I would like to ask you experts, when I use ATmega644, I use the AD port as the output to control the MOS tube, and the output high level should be 5v. Because I connected a 1k resistor to the output ...
DC-DC converters power individual circuits throughout the system. While each circuit may perform well on the test bench, the overall system performance often does not match the performance of the indi...
The project name is J1049. During the compilation process, this error J1049.axf: error: L6031U: Could not open scatter description file J1049.sct: No such file or directory appeared. After selecting t...
I plan to make an infrared alarm device: it uses infrared rays to determine whether it is blocked, and if so, it will sound an alarm.It is divided into two parts: the transmitter sends out an infrared...
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]
introduction In the general project development process, two or more microcontrollers are often required to communicate to complete data transmission. For example, a quadcopter wirelessly transmits d...[Details]

In the project, CPLD is needed to complete part of the algorithm design. The parameters are given by AVR, so the communication between AVR and CPLD needs to be completed. Therefore, a test program is...[Details]
When Amazon quietly launched a product called Elastic Computing Cloud 12 years ago, the Internet industry in China, across the ocean, also ushered in an unprecedented development opportunity. Let's...[Details]
1. What is PWM What is PWM? Professionally speaking, it is pulse width modulation. In layman's terms, it is the continuous output of high and low levels. For example, the microcontroller outputs...[Details]
For complex calculations, the speed of the microcontroller is too slow. The best way is to manually calculate all the results in advance, store them in ROM in sequence, and then directly check the re...[Details]
Design a second and minute pulse generator for a single-chip microcomputer using the interrupt method. Assume that P1.0 generates a positive pulse of one machine cycle per second, and P1.1 generates ...[Details]
