Serial EEPROM

Stored values of configuration parameters, stored values of unlock codes, stored and working table of macros.

Memory usage for the Radio Control Board

Program ROM

Executable code and the library of sound sequences. digital pots settings, tone definitions and amplitudes, ID frequency, speed, and amplitude are downloaded from the CPU board when the system is reset. Most of the parameter set functions change the CPU board stored values, but do not download the values to the Radio Control Boards (digital pot setting is an exception, as it must be interactive).

Therefore, if the ID is changed, the system must be reset for it to be effective. There is space in the serial EEPROM for storing the working copy and two backups of

the configuration parameters, unlock code table, and macro table. The parameter backup and restore commands are used to copy the data from one of these copies to the other.

Configuring the System - Parameter Storage

Most parameters defining operation of the controller are represented by global variables of the CPU board program. They are stored in a serial EEPROM from which they are loaded on booting the program. The EEPROM contains three copies of the controller configuration parameters, designated working copy, backup, and deep backup. The working copy is generally synchronized with the RAM copy of the parameters. Some parameters can be set with an individual command to the CPU board via the RS232 serial port or DTMF received by one of the radios. These commands check parameters and most set both the RAM and EEPROM working value. Other parameters are set by writing directly to the corresponding address in the serial EEPROM. The working copy can be copied to and from the backup copy and the backup copy can be copied to and from the deep backup copy, via DTMF commands. Macros are stored only in the serial EEPROM, and not in microprocessor RAM, except as they are being executed.

The commands for changing specific parameters do input range checking and change both RAM and eeprom, so the effect of the command may be determined immediately. Specific commands are not provided for changing many of the. There are commands to change the value of any address in EEPROM directly. This should not normally be invoked manually from DTMF, as a mistake can corrupt the EEPROM. When used over RS232 from a controlling program on an attached PC, it will provide a mechanism for efficiently configuring all parameters of the system.

Some parameters are stored differently.

1.The command translation table, which translates a sequence of DTMF characters into a word length internal command, is stored in program ROM. Because the PIC processor is capable of reprogramming itself, this table will be able to be customized in the field. This capability is not available in program v0.90.
