The demo firmware provided will help you get started in using the SMT911 for
whatever custom applications are required. It is not meant to demonstrate the
hardware in its full capabilities, but to provide an example use for the device and an
example setup for configuration and control. It was developed using 3L‟s Diamond
development IDE for multiprocessor systems.
“SMT_control” is an NGC block for receiving instructions from a Sundance DSP
module, and passing on these control words to the SMT911 board. Some modules
which are integrated in this block are:
• Control Comport: receive instruction words, and send back register contents
to DSP.
• Switching Controller: run switching (TX, RX, Standby, etc.) of SMT911 board.
• SPI: send SPI signals to every corresponding chip on the SMT911 board.
• RSSI ADC: convert the RSSI and Power Detection information into register
words.
“SMT_data” is a block for data transfer between the ADDAC data pins and a
Sundance DSP module through an RSL interface. Using this RSL link, a sustained
