32 microcontroller uses GPIO to simulate IIC timing
The GD32f470 microcontroller is used. Since the main frequency of each microcontroller is different, you need to use a logic analyzer to check the waveform to see if there are signals such as start, end, writing data, reading data, response, and no response. Normal write timing Normal read timing Special attention is paid to: Writing […]

Deciphering the timing mystery of concurrent programming: Uncovering the mystery of Happens-Before
High-quality blog posts: IT-BLOG-CN 1. Introduction Why the happens-before principle is needed: Mainly because of the Java memory model. In order to improve CPU efficiency, the working memory Cachereplaces main memory. Modifying this critical resource will update work memory but not necessarily flush it to main memory immediately. Usually JMM compiles and executes the written […]
How to add timing constraints in the FPGA design environment?
Click the blue words to follow us Follow and star the public account, and exciting content will be delivered every day Source: Internet material When doing logic synthesis and placement and routing for FPGA, timing constraints need to be set in the tool. Usually, in FPGA design tools, FPGA contains four paths: pure combinational logic […]
2023-Autumn Timing-32-bit shift register-difficulty upgraded version BUAA power collection
1. Title description: This topic will learn the design of commonly used shift registers and implement the barrel shifter needed in shift instructions. Background: The shift register moves the data stored in it by one bit in a certain direction according to its control signal at the trigger edge of the clock. Shift registers are […]
20.2 Timing initialization implementation and memory test of FMC driver SDRAM
Continuing the topic of the previous article, I wrote that after the SDRAM is configured through CubeMx, when writing the engineering code, I directly reference the timing initialization and memory test files I wrote in advance without explaining them in detail, so this article will Come and tell the story. Without further ado, let’s get […]
C++ implements read-write lock based on timing fairness
Function of read-write lock The difference between read-write locks and ordinary mutex locks is that there are two locking methods: read locks and write locks. The read lock acquired by different users on the same read-write lock is non-mutually exclusive, and other situations (read lock and write lock, write lock and write lock) are mutually […]
LCD12864 data writing method (how to write 16-bit characters through 8-bit variables) and timing issues
Write the directory title here Write step by step through string pointer Loop through string array bits Write character by character (write one character at a time) Timing issues Read operation timing odd function Write operation timing and functions bug1 1. After writing the address, write the data. For example, when RS changes, the period […]
