4.2Interfaces

4.2.1ASC0 - Serial Device

ASC0, an Asynchronous Serial Controller, is a 9-wire serial interface. It is described in the Hardware Interface Description [4]. Without a running Java application the module can be controlled by sending AT commands over ASC0. Furthermore, ASC0 is designed for transferring files from the development PC to the module and for controlling the module with AT commands. When a Java application is started, ASC0 can be used as an RS-232 port. Refer to the Java doc [5] for details.

4.2.2General Purpose I/O

There are ten I/O pins that can be configured for general purpose I/O. When the TC65 starts up, all 10 pins are set, by default, to a high-impedance state for use as input. One pin can be configured as a pulse counter. All lines can be accessed under Java by AT commands. See [3] and [4] for information on configuring the pins.

4.2.3DAC/ADC

There are two analogue input lines and one analogue output line. They are accessed by AT commands. See [3] and [4] for details.

4.2.4ASC1

ASC1 is the second serial interface on the module. This is a 4-pin interface (RX, TX, RTS, CTS). It can be used as a second AT interface when a Java application is not running or by a running Java application as System.out.

4.2.5Digital Audio Interface (DAI)

The TC65 has a seven-line serial interface with one input data clock line and input/output data and frame lines to support the DAI. Refer to the AT Command Set [3] and Hardware Interface Description [4] documents for more information.

4.2.6I2C/SPI

There is a 4 line serial interface which can be used as I2C or SPI interface. It is described in the Hardware Interface Description [4]. The at^sspi at command configures and drives this interface. For details see [4].
