Chapter 5 Software Installation and
Programming Guide
5.1. Introduction
5.1.1 LCD Control Module
The LCM (short for LCD Control Module) APIs provide interfaces to control the module. By
invoking these APIs, programmers can implement the applications which have the functions listed
below:
1. Clear LCD screen.
2. Turn on or off the cursor on the screen.
3. Move the cursor on the screen.
4. Turn on or off the text on the screen.
5. Get the identification of the pressed key of the LCM.
6. Show the text on the screen.
5.1.2 Watchdog
AMB-IB75N1 provides Watchdog timer. Users can use the Watchdog APIs to configure and to
access the Watchdog timer. The Watchdog timer can be set to 1~255 seconds. Setting the timer to
zero disables the timer. The remaining seconds of the timer to reboot can be read from the timer.
In this Watchdog package, we provides:
1. Watchdog test utility.
5.1.3 LAN Bypass Subsystem
Two pairs of LAN ports on AMB-IB75N1 implement the bypass function. Users can invoke the
LAN Bypass APIs to control the bypass states of the LAN ports and set up the LAN Bypass
Watchdog timer ( this watchdog timer is different from the system watchdog timer mentioned in the
previous paragraph ).
