1. Functions Supported by BPI
1) Watchdog
Supports Watchdog Startup, Stop and Feed Dog functions.
2) GPIO
Supports GPIO input/output programming.
3) Hardware monitoring
Supports monitoring of motherboard CPU temperature, system temperature, fan
speed and motherboard core voltage detection, such as CPU Core voltage,
V12.0, battery voltage, etc.
4) Flash programming
The motherboard provides one OEM Flash by default, which is used to store
private data of users, such as key and product serial number. The size can be
acquired by BPI library function.
Users can carry out second development by using BPI library based on
application needs, for example:
a) Detecting CPU temperature. If temperature is too high, alarm buzzer will
be triggered.
b) Peripheral device can be controlled by GPIO programming.
2. Advantages of BPI
1) Platform Irrelevant
The interfaces provided by BPI for application layer, i.e. BPI library function is
irrelevant to platform, therefore the software developed by using BPI library
function can operate on a new platform, supporting BPI function, normally
without making any modification.
2) Security and High Reliability
The BPI library function accessing the hardware is programmed by the
motherboard developer and is strictly tested; therefore, it can avoid system
malfunction caused by improper operation of the system hardware.
3) Easy Maintenance
Traditional WDT and GPIO programming are closely related to the hardware
with complicated test and debug process and software of different platforms;
