Source: Semiconductor Industry Alliance MCU is the abbreviation for Microcontroller Unit, commonly known as a microcontroller. It reduces the frequency and specifications of the CPU appropriately and integrates memory, counters, USB, A/D converters, UART, PLC, DMA, and even LCD driver circuits onto a single chip, forming a chip-level computer for different application scenarios. MCU can … Read more
Parallel programming, the earliest programming method, is the most powerful, but requires connecting more pins, usually needing a high voltage of 12V~24V for distinction, referred to below as high voltage parallel programming. ISP (In System Programmability) is in-system programming, abbreviated as serial download. IAP (In Application Programming) refers to application programming, similar to BootLoader. 1 … Read more

Since programming TI’s DSP is slightly more complex than that of microcontrollers, many customers are not very familiar with the programming process. Therefore, we will provide a simple introduction to the programming methods. DSP generally adopts an online programming method, which means there is a connected JTGA interface on the circuit board. The programming tool … Read more
One ARM Assembly Generally, our computers are X86 architecture machines. Here we use clang to compile our files. Compiling files by ourselves and using IDA to learn alongside makes it easier to understand. Two Some instructions about clang: Using clang to directly compile into an executable file // Compile our file into ARMv5 architecture file … Read more
Some rankings can remain unchanged for centuries, like the eight masters of the Tang and Song dynasties. The names of Han Yu, Liu Zongyuan, Ouyang Xiu, Su Xun, Su Shi, Su Zhe, Zeng Gong, and Wang Anshi will never be replaced. Some rankings change annually, such as the annual box office rankings for movies. There … Read more
To learn ARM, one must learn ARM instructions. ARM instructions are the interface provided to us by the CPU, and they are the key to unlocking the Pandora’s box of the CPU. There are many ARM instructions. To help everyone get started quickly, I have compiled some of the most helpful instructions. For the operation … Read more
Click the blue text Follow us Source from the Internet, please delete if infringing Now let’s write a simple application that prompts the user to input an integer and multiplies it by powers of 2 (2¹ to 2ⁿ) using bit shifting, displaying each product with leading spaces. The input-output will use C++. The assembly module … Read more
The problem is relatively simple but tests the basics of binary assembly.I personally think that the fundamentals are veryimportant, so I spent some time carefully studying this problem to solidify my foundation.If it wereoffline, without GPT’s help, contestants would need a solid understanding of assembly to conduct a detailed analysis of the problem. If you … Read more
