SOFTWARE
An Application Program Interface (API) is included. This interface consists of a library of high-level language functions that allow the user to write custom applications programs without having to understand the “nuts and bolts” of the SBC-UADI-ARTIC-RS-1553 system. When using the API, a user need not concern himself with the settings of the individual bits of the MIL-STD-1553 words, nor with the word ordering and timing prescribed by the standard; these tasks are handled automatically by the system software.
 
 
APPLICATIONS
The UADI-ARTIC-RS-1553 may be used for many types of testing and simulation operations. The system may be configured as a Bus Controller, Remote Terminal, or Bus Monitor. Within each of these categories, flexibility is given to the user to custom tailor the most suitable test program for his needs
 
UADI-ARTIC-RS-1553 OPERATION.
 
The UADI-1553 has an internal memory of 2kx16. This memory is used for data transmission.
BC mode requires the user store data to be transmitted at any location in segments of 64 words. The user loads the size with the memory location in a internal register and immediately the BC start to transmit.
RT mode used the memory as data response for a BC command. Each sub address has 32 words. A total of 1024 words; 32 sub addresses each with 32 words.
 
Example for RT sub address data stored:
    Internal_address = 0 ;
    if RT== 1)   Internal_address = 0x800 ;    
    for (i=0 ; i<range; i++)
    {
             Address = sub_address * 32 + i ;
             WriteDPM ( Address + Internal_address , (char *)&data to be stored, 1) ;
    } 
 
UADI BOARD HARDWARE
         
The SBC UADI is based on two ICs: a microcontroller from TI (MSP430F149) and a FPGA from Xilinx (XC2S100). The following signals from the microcontroller create the handshake between the parts:
 
Port2 –
 0 – RD control signal
1 – WR control signal
6 – ARINC data received interrupt signal
7 – 1553 data received interrupt signal
 
Port3 –
 0 – ADDRESS 0
1 – ADDRESS 1
2 – ADDRESS 2
3 – ADDRESS 3
 
The libraries included with the board have all registers definition.
                                                                       
 
Port4–
 0-7 –  L.S.BYTE data bus (bidirectional).
 
Port5–
 8-15 – M.S. BYTE data bus (bidirectional).
 
Port6– bits
            0 – Control signal to enable FPGA voltage supply – 0 disable 1-enable
            1-7 – signals connected to H5 (7x2- odd pin numbers) to be used as hardware debug.

RS232 CHANNELS
 
The SBC UADI board has two RS232 channels. The channels are embedded in the microcontroller MSP430F149/169 from TI. A detail explanation about the UART operation is available in the TI microcontroller data book.
 
 
INPUT/OUTPUT
 The SBC UADI board has eight general I/O ports. The I/O ports are embedded in the microcontroller MSP430F149/169 defined as PORT 6. A detail explanation about the UART operation is available in the TI microcontroller data book.
Please note the maximum input signal should be 3.4 Volt.
 
Internal Jumpers
The FPGA can be programmed by the CPU (parallel) or by he PROM (serial) on board.
Header JP7 specify if Data in comes from CPU or PROM. If the CPU is selected JP3 must be open.
Jumper J1 enable to program the CPU using the RS232 serial port.
