Microcontroller Unlock also known as microcontroller Attack or Microcontroller Break, but strictly speaking these types of call are not scientific, but it has become accustomed to it is called, we roughly define CPLD decryption, DSP decryption as IC Crack. MCU is only one type of ICs which can load program. IC which can load program and can also encrypted includes DSP, CPLD, PLD, AVR, ARM, etc. There are also IC chips with special encryption algorithm for encryption IC chips and manufacturer code verification , such IC chip can achieve the purpose of preventing copying of electronic products.
Microcontroller Firmware Instruction
Microcontroller Firmware Instruction will be executed after programmed into the MCU, and engineer should have the idea about the meaning of it: MOV: This is an instruction that means conveying data. When it comes to delivery, we all know that it is n...
Microcontroller Memories Classification
Microcontroller Memories can be divided into two categories of read-only and random access memory according to the function. The so-called read-only, literally understood can only be read from inside, can not be written in, it is similar to our books...
How the MCU Memory Works
In order to figure out How the MCU Memory Works, it is necessary to learn its struture, MCU Memory is where the data and program is stored. It uses the high and low electrical level to store the data and program, as a result of that, it stores the hi...
Microcontroller Internal Storage Structure Analysis
When we write an instruction into the microcontroller through the programmer, and then remove the microcontroller, the microcontroller can execute this instruction, then this instruction must be saved somewhere in the microcontroller, and this The pl...
How to Write a Program Microcontroller Can Execute
How to Write a Program Microcontroller Can Execute, To execute an instruction on a microcontroller, you have to send commands to the microcontroller which can understand are called computer instructions. Our first task is to use a microcontroller to ...
Microcontroller Pin Definition
Microcontroller Pin Definition can be roughly divided into four categories: power supply, clock, control, and I/O pins. 1. Power supply: (1) VCC – chip power supply, connected to +5V; (2) VSS – ground terminal; 2. Clock: XTAL1, XTAL2 R...
Microcontroller Introduction
At present, Microcontroller penetrates into various fields of our lives, and it is almost difficult to find which field has no trace of the microcontroller. Small to phone, toy, mobile phone, all kinds of credit card machines, computer keyboards, col...
CPU Register Used in the Microcontroller
The machine instructions for each CPU inside Microcontroller are different, so the corresponding assembly language is different. This article describes the most common x86 assembly language currently available, which is the one used by Intel’s ...
What is Assembly Language
What is Assembly Language? Assembly language is a low-level language that directly describes/controls the operation of the CPU. If you want to know what the CPU is doing and how the code runs, be sure to learn assembly language. We know that the CPU ...
FPGA & CPLD Difference
FPGA & CPLD Difference is mainly based on its structural characteristics and working principle. The usual classification method is: cpld and fpga architecture Devices that form a logical behavior in a product term structure are called CPLDs, such...
