VB is visual programming, that is, drag some icon controls onto the programming board, and then write the implementation function of each button with code (such as what happens when you press the button) vb was very popular in the past few years and gradually faded out of people's vision in recent years, but it is very convenient to use it to ...

Recording IC Test & verification practice 2020.11.13 - 2021.1.22 Although it's been a long time hhh, I feel that I can sort out what I learned in my senior internship. The internship part is divided into two parts: Test (7 days to move bricks) & verification part (free study for more than 1 month) 1. Chip test (formed chip) 1.1 task 1 ...

1, Hardware STM32F103C8T6, thermistor sensor, OLED. 2, Introduction of thermistor sensor A DO output port outputs digital quantity, and outputs 0 or 1 according to whether the external temperature exceeds the threshold of the sensor; An AO port outputs analog quantity. The detection of temperature shall be realized through analog quant ...

Introduction to infrared The visible light that can be seen by human eyes is arranged according to the wavelength from long to short, which is red (660nm), orange (610nm), yellow (585nm), green (555nm), green (500nm), blue (460nm) and violet (405nm). Light shorter than the wavelength of violet light is called ultraviolet, and light longer than ...

1.SPI protocol SPI is the abbreviation of Serial Peripheral Interface. It is a high-speed, full duplex and synchronous communication bus, and only occupies four wires on the pins of the chip. They are the following four MISO – Master Input Slave Output, master equipment data input and slave equipment data output;MOSI – Master ...

preface PingPong routine has provided a complete low-power processing framework. Users only need to open the application low-power macro definition for testing. When expanding, users only need to add low-power processing in their own functional modules to complete the low-power processing of the whole project. It is very convenient and r ...
