An Image acquisition device for a CMOS digital image sensor typically uses a high-performance processor or CPLD/FPGA. When the image is gray and its resolution is not high, MCU can be applied. There are many acquisition methods employed. This paper describes a binary image inquiry method based on the microcontroller Serial Peripheral Interface (SPI). Using the SPI interface can decrease requirements...
Software reverse engineering in embedded system is not convenient than it on the PC. There are many debugging and analysis software on the PC. In embedded systems, due to the diversity types of processors, it is difficult to make software tools using anywhere. However, the diversity types of processors also provide us with convenience. We can use some special features of the processors to complete...
In order to compensate for functional defects or add new features of an embedded product, the designer need to continuously update the system program. With the development of network technology, the end-user can download the update program through the network and complete the update process. But for the unattended equipments, they are often used of automatic remote update. On-line programming function...
