2.1 Packet Structure
Each SIPP firmware packet is comprised of 6 or more bytes. The following table outlines the packet
structure:
PACKET STRUCTURE
*Note: Each transceiver in the system must have a unique ID. ID:0 is reserved for broadcast packets sent by
2.2 Reserved EEPROM Locations
The EEPROM memory is a feature of the preprogrammed SIPP firmware and, as such, is only available
when using the DLP-RF1 with its firmware as shipped from DLP Design.
The EEPROM memory used by the SIPP firmware consists of a block of 32 bytes that reside within the
Flash program memory of the MC9S08GT60. The first 10 bytes (0-9) and the last byte (31) are reserved
for storing transceiver settings and checksum. Bytes 10 through 30 (user area) are available for use by
the user’s host software.
Whenever the data in any EEPROM location is changed, the checksum location (EEPROM Location 31)
is automatically updated. At power up or reset, if ever the calculated checksum for the first 31 bytes
does not match the value at EEPROM Location 31, the Default Reset values for the transceiver settings
are restored, and the checksum is recalculated and rewritten. The values in the user area are preserved.
Additionally, if JP1 is shorted at power up (or reset), the default values for the transceiver settings are
restored, and the checksum is recalculated and rewritten. Again, values in the user area are preserved.
The following table outlines usage of the reserved EEPROM locations. These values are read at power
up, reset, or via SIPP firmware:
