Note:
1. In Proteus, You can import elf files, which means you do not have to generate hex files.
2. The key point is to eliminate the shadow, which is not found in the original book. It may be a mistake or omission in writing books.

The s5pc100's Proteus microprocessor supports multi-host I2C bus serial interfaces. A dedicated serial data cable (SDA) and a serial clock line (SCL) transmit information between the bus host and peripheral devices connected to the I2C bus. The SDA and SCL lines are bidirectional.
In multi-host I2C bus mode, multiple microprocessors are sent to or received from the slave device. The host s5pc100 starts and terminates a data transmission on the I2C bus
banks, and other industrial fields. I tried to port the 802.11g wireless network card to the Development Board, and successfully achieved wireless communication with the host, making the system more convenient.Attach. According to the research on supermarkets in Nanjing university campuses, this system is estimated to produce an economic benefit of 0.5 million yuan.

Format [drive:] [/fs: file-system]
Parameters
Drive:
Specify the drive to be formatted. The disk cannot be formatted from the fault recovery console.
/Q
Quickly format the drive. Do not scan the drive to see if there is any bad area, so you should only use this parameter for previously formatted drives.
/Fs: file-system
Specify the file system to use: FAT, FAT32, or NTFS. If no file system is specified, the existing file system format is
