'''SUSI – A Bridge to Simplify & Enhance H/W & Application Implementation Efficiency'''

When developers want to write an application that involves hardware access, they have to study the specifications to write the drivers. This is a time-consuming job and requires lots of expertise.

Advantech has done all the hard work for our customers with the release of a suite of Software APIs (Application Programming Interfaces), called '''Secured & Unified Smart Interface''' (SUSI).

SUSI 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. SUSI plays the role of catalyst between developer and solution, and makes Advantech embedded platforms easier and simpler to adopt and operate with customer applications.



== '''1.1 Functions''' ==

=== '''1.1.1 GPIO''' ===

[[File:1.1.1 GPIO.png|100x150px|1.1.1 GPIO.png]]

General Purpose Input/Output is a flexible parallel interface that allows a variety of custom connections. It supports various Digital I/O devices – input devices like buttons, switches; output devices such as cash drawers, LED lights…etc. And, allows users to monitor the level of signal input or set the output status to switch on/off the device. Our APIs also provided Programmable GPIO and allows developers to dynamically set the GPIO input or output status.



=== '''1.1.2 SMBus [x86 only and RISC is unavailable]''' ===

[[File:1.1.2 SMBus.png|100x150px|1.1.2 SMBus.png]]

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. Today, SMBus is used in all types of embedded systems. The SMBus APIs allows a developer to interface a platform to a downstream embedded system environment and transfer serial messages using the SMBus protocols, allowing multiple simultaneous device control.



=== '''1.1.3 I<sup>2</sup>C''' ===

[[File:1.1.3 i2c.png|100x150px|1.1.3 i2c.png]]

I<sup>2</sup>C is a bi-directional two wire bus that was developed by Philips for use in their televisions in the 1980s. Today, I<sup>2</sup>C is used in all types of embedded systems. The I<sup>2</sup>C API allows a developer to interface a platform to a downstream embedded system environment and transfer serial messages using the I<sup>2</sup>C protocols, allowing multiple simultaneous device control.



=== '''1.1.4 Watchdog''' ===

[[File:1.1.4 watchdog.png|100x150px|1.1.4 watchdog.png]]

A watchdog timer (WDT) is a device or electronic card that performs a specific operation after a certain period of time if something goes wrong with an electronic system and the system does not recover on its own.

A watchdog timer can be programmed to perform a warm boot (restarting the system) after a certain number of seconds during which a program or computer fails to respond following the most recent mouse click or keyboard action.



=== '''1.1.5 Hardware Monitor&nbsp;[x86 only and RISC is limited in some features]''' ===

[[File:1.1.5 HardwareMonitor 1.png|100x150px|1.1.5 HardwareMonitor 1.png]] &nbsp; [[File:1.1.5 HardwareMonitor 2.png|100x150px|1.1.5 HardwareMonitor 2.png]]

The Hardware Monitor (HWM) APIs is a system health supervision API that inspects certain condition indexes, such as smart fan, fan speed, temperature, current, case open and voltage.



=== '''1.1.6 Backlight Control''' ===

[[File:1.1.6 Backlight 1.png|100x150px|1.1.6 Backlight 1.png]] &nbsp; [[File:1.1.6 Backlight 2.png|100x150px|1.1.6 Backlight 2.png]]

The Backlight Control APIs allows a developer to interface platform to easily control brightness through PWM and backlight on/off.



=== '''1.1.7 Storage&nbsp;[x86 only and RISC is unavailable]''' ===

[[File:1.1.7 Storage.png|100x150px|1.1.7 Storage.png]]

Storage is a non-volatile storage, the storage APIs allows a developer to access storage information, read/write data to storage and lock/unlock data area (same like write protection) by a key.



=== '''1.1.8 Thermal Protection&nbsp;[x86 only and RISC is unavailable]''' ===

[[File:1.1.8 Thermal 1.png|100x150px|1.1.8 Thermal 1.png]] &nbsp; [[File:1.1.8 Thermal 2.png|100x150px|1.1.8 Thermal 2.png]]

Thermal Protection can select a thermal source to monitor. When source temperature reach the limit, SUSI can act protect function to protect system.

== '''1.2 Benefits''' ==

*'''Faster Time to Market'''

:SUSI's unified API helps developers write applications to control the hardware without knowing the hardware specs of the chipsets and driver architecture.



*'''Reduced Project Effort'''

:When customers have their own devices connected to the onboard bus, they can either: study the data sheet and write the driver & API from scratch, or they can use SUSI to start the integration with a 50% head start. Developers can reference the sample program on&nbsp;the CD to see and learn more about the software development environment.



*'''Enhances Hardware Platform Reliability'''

:SUSI provides a trusted custom ready solution which combines chipset and library function support, controlling application development through SUSI enhances reliability and brings peace of mind.



*'''Flexible Upgrade Possibilities'''

:SUSI supports an easy upgrade solution for customers. Customers just need to install the new version SUSI that supports the new functions.



*'''Backward compatibility'''

:Support SUSI 3.0, iManager 2.0 and EAPI 1.0 interface. Customers don’t need to change any APIs in their applications.

=== '''3.6 Watchdog Functions''' ===

After the watchdog timer has been start function it must be triggered within (Delay + Event Timeout) milliseconds as set with the start function, following the initial trigger every subsequent trigger must occur within (Event Timeout) milliseconds. Should trigger not be called within the relevant time limit a system reset will occur. The SUSI watchdog timer may support two stages. If the watchdog is not triggered within the event timeout, an NMI, IRQ, or hardware output will be generated. Then the reset timeout becomes active. If the watchdog timer is not triggered within the reset timeout a reset will be generated

== '''3.8 Smart Fan Functions''' ==

The Smart Fan function call is used to set fan speed configuration. You can use this function to easily control the fan speed. It takes a pointer to an instance of structure ''SusiFanControl'', which is defined as follows:

{| border="1" cellspacing="0" cellpadding="0" style="margin:1em auto 1em auto;"
|-
| style="width:598px;height:582px;" | <pre>#define SUSI_FAN_AUTO_CTRL_OPMODE_PWM 0

#define SUSI_FAN_AUTO_CTRL_OPMODE_RPM 1

typedef struct _AutoFan {

 uint32_t TmlSource; // Thermal source

 uint32_t OpMode;

 uint32_t LowStopLimit; // Temperature (0.1 Kelvins)

 uint32_t LowLimit; // Temperature (0.1 Kelvins)

 uint32_t HighLimit; // Temperature (0.1 Kelvins)

 uint32_t MinPWM; // Enable when OpMode == FAN_AUTO_CTRL_OPMODE_PWM

 uint32_t MaxPWM; // Enable when OpMode == FAN_AUTO_CTRL_OPMODE_PWM

 uint32_t MinRPM; // Enable when OpMode == FAN_AUTO_CTRL_OPMODE_RPM

 uint32_t MaxRPM; // Enable when OpMode == FAN_AUTO_CTRL_OPMODE_RPM

} AutoFan , *PAutoFan&nbsp;;



// Mode

#define SUSI_FAN_CTRL_MODE_OFF 0

#define SUSI_FAN_CTRL_MODE_FULL 1

#define SUSI_FAN_CTRL_MODE_MANUAL 2

#define SUSI_FAN_CTRL_MODE_AUTO 3

typedef struct _SusiFanControl {

 uint32_t Mode;

 uint32_t PWM; // Manual mode only (0 - 100%)

 AutoFan AutoControl; // Auto mode only

} SusiFanControl, *PSusiFanControl;
</pre>

|}

If Mode member of SusiFanControl is not Auto, AutoControl member will be ignored. In auto mode, parameter “TmlSource” is use ''SUSI_ID_HWM_TEMP_XXX'' ('''Table 3''') to select which thermal type to reference. If TmlSource is not match any temperature ID means unknown or unsupported.
