Figure 6-1 Overview of Evaluation Application
In terminal mode the user can talk directly to the evaluation application programmed
into the AVR microcontroller. This evaluation application is a thin layer of code that
defines a command interface on top of the IEEE 802.15.4 stack from Atmel. The
responsibilities of the evaluation application are:
• Start a new network.
• Associate to the network.
• Send data over the wireless link.
• Notify when new data is available.
• Reset the IEEE 802.15.4 MAC and evaluation application.
This section will describe the command interface that resides on top of the IEEE
802.15.4 MAC library. Commands are sent to the AVR microcontroller by using its
serial communication interface (USART). Every command described in the latter part
of this subsection can be tried out by connecting the STK501 top module to one of the
PC’s COM ports. Type in the test command in your favorite terminal application
(Hence the name terminal mode), append CR + LF (Carriage Return + Line Feed =
ASCII “\r\n”) before executing.
Before continuing, the following formats are used in Table 6-1 through Table 6-5:
• Characters in quotation marks are the actual text sent to the AVR.
• Optional commands and response parameters are enclosed in brackets.
The ”AT+R” command is used to reset the command interface and the IEEE 802.15.4
MAC. See Table 6-1 for details.
