Provides not only the underlying drivers required but also a rich set of user-friendly, intelligent and integrated interfaces, which speeds development, enhances security and offers add-on value for Advantech platforms. It plays the role of catalyst between developer and solution, and makes Advantech embedded platforms easier and simpler to adopt and operate with customer applications. Software APIs Control Monitor General Purpose Input/Output is a flexible parallel interface A watchdog timer (WDT) is a device that performs a specific that allows a variety of custom connections. It allows users operation after a certain period of time if something goes wrong to monitor the level of signal input or set the output status to and the system does not recover on its own. switch on/off a device. Our API also provides Programmable A watchdog timer can be programmed to perform a warm boot GPIO, which allows developers to dynamically set the GPIO (restarting the system) after a certain number of seconds. GPIO Watchdog input or output status. ® SMBus is the System Management Bus defined by Intel Corporation in 1995. It is used in personal computers and servers for low-speed system management communications. The Hardware Monitor (HWM) API is a system health The SMBus API allows a developer to interface a embedded supervision API that inspects certain condition indexes, such as system environment and transfer serial messages using the fan speed, temperature and voltage. Hardware SMBus protocols, allowing multiple simultaneous device SMBus Monitor control. 2 I C is a bi-directional two wire bus that was developed by Philips for use in their televisions in the 1980s. The Hardware Control API allows developers to set the PWM 2 The I C API allows a developer to interface with an embedded (Pulse Width Modulation) value to adjust fan speed or other 2 system environment and transfer serial messages using the I C devices; it can also be used to adjust the LCD brightness. Hardware 2 protocols, allowing multiple simultaneous device control. I C Control Display Power Saving Make use of Intel SpeedStep technology to reduce power power The Brightness Control API allows a developer to interface with consumption. The system will automatically adjust the CPU an embedded device to easily control brightness. Speed depending on system loading. Brightness CPU Speed Control Refers to a series of methods for reducing power consumption in The Backlight API allows a developer to control the backlight computers by lowering the clock frequency. These APIs allow the (screen) on/off in an embedded device. user to lower the clock from 87.5% to 12.5%. System Backlight Throttling Software Utilities The BIOS Flash utility allows customers to update the flash The eSOS is a small OS stored in BIOS ROM. It will boot up in ROM BIOS version, or use it to back up current BIOS by case of a main OS crash. It will diagnose the hardware status, copying it from the flash chip to a file on customers’ disk. The and then send an e-mail to a designated administrator. The BIOS Flash utility also provides a command line version and eSOS also provides remote connection: Telnet server and FTP API for fast implementation into customized applications. server, allowing the administrator to rescue the system. BIOS Flash eSOS The embedded application is the most important property of Flash Lock is a mechanism that binds the board and CF card a system integrator. It contains valuable intellectual property, (SQFlash) together. The user can “Lock” SQFlash via the Flash design knowledge and innovation, but it is easily copied! The Lock function and “Unlock” it via BIOS while booting. A locked Embedded Security ID utility provides reliable security functions SQFlash cannot be read by any card reader or boot from other for customers to secure their application data within embedded platforms without a BIOS with the “Unlock” feature. Embedded Flash Lock BIOS. Security ID The Monitoring utility allows the customer to monitor system health, including voltage, CPU and system temperature and fan speed. These items are important to a device; if critical errors happen and are not solved immediately, permanent damage may be caused.
