4.4Handling Interfaces and Data Service Resources

To develop Java applications the developer must know which resources, data services and hardware access are available.

There are three AT parsers available

There is hardware access over

-two serial interfaces: ASC1 (System.out only) and ASC0 (fully accessible).

-general purpose I/O. To configure the hardware access, please refer to the AT Command Set [3] and the Hardware Interface Description [4].

-I2C/SPI

-All restrictions of combinations are described in section 4.4.1.

A Java application has:

-three instances of the AT command class, one with CSD and two without, each of which would, in turn, be attached to one of the three AT parsers.

-one instance of access to a serial interface, ASC0, through the RS-232 API.

-System.out over the serial interface, ASC1, for debugging.

4.4.1Module States

The module can exist in the following six states in relation to a Java application, the serial interfaces, GPIO and I2C/SPI. See the AT Command Set [3] for information about any AT commands referenced. A state transition diagram is shown in

Figure 10.

This section shows how Java applications must share AT parsers, GPIO pins and I2C/SPI resources. DAC, ADC and DAI are not discussed here. The USB interface is an alternative to ASC1. When the USB is plugged in, the ASC1 interface is deactivated.
