Article Title: hardware simulation implementation-Design and Implementation of SkyEye. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 　　 I. Overall structure of SkyEye SkyEye is based on GDB/armulator (currently maintained by David McCullough) and has been fully changed and expanded. SkyEye is built on the bottom layer of gnu gdb and can imitate a variety of

This is the past DOS era of the compilation of source code, although has passed, but for the study of the assembly is still helpful, assembly language is just a basic programmer language, most people can grasp, not necessarily in-depth research.

networked on the bus to achieve multi-machine communication, the bus allows to hang a plurality of transceivers, from the existing RS485 chip, can be hung 32, 64, 128, 256 and other devices of different drives. The interface of the RS485 is very simple, similar to the MAX232 used by RS232, only requires a RS485 converter, it can be directly connected with the UART serial port, and the use of the same asynchronous serial communication protocol. Howeve

there are two i²c devices connected to the bus, and their addresses are 0x48 and 0x77 respectively. If you do not see a device, check the hardware connection, and remember to open the system config inside the i²c.Then still the sample code: Import time Import SMBus addr=0x48 cmd=0xab # open/dviev/i2c-1 bus = SMBus. SMBus (1) # Read and write data, Case 1 Data = bus.read_byte (addr) bus.write_byte (addr, data+1) # Read and write data, Case 2 = Bus.read_byte_data (addr, cmd) bus.write_byte_dat

selective in-depth analysis, each individual has different pursuits for knowledge points and is difficult to meet everyone's needs. Personally, I will be interested in android Wi-Fi sleep strategy and Location Network Positioning, this is related to problems encountered in actual work. 3) "NFC and GPS problems are very few", which may be related to whether the function modules are widely used and the application breadth. If more modules are used, more problems may be exposed, many application s

Android studio, androidstudio The current work is related to Bluetooth, so I am eager to develop Android devices to debug my firmware, After installing Android Studio and SDK, I would like to thank nordic for its public code and study it for a while. There are two related codes. The Android-nRF-Toolbox was first found. This code is more comprehensive and needs to be debugged here, But... For a person I don't know much about, it's still a little hard to understand, and I don't dare to modify i

Just like the crawler conveyors on the assembly line, all we have to do is put the goods on top (not to try to figure out how to build the transport), of course, we have to know how to put, below we l
