VersaBoard-8052 and TrakBox JA6FTL Feb.29.1992 Background The desire to be able to rotate and elevate antennas to track a satellite without interfering with the other applications on a PC lead to the original Tracker Box project by SM0TER. The original design used the Micro Mint 8052BASIC processor board and their 12 bit ADC board with a RTC chip. Software was written to track one of six satellites in real time and to control the radio. The project was taken a step farther by JA6FTL and JA1OGZ when they designed a PCB using the Intel 8052AH-BASIC processor,NEC PD7004C 10 bit ADC,8255PIO and a real time clock. Many discussions and exchanging schematics CAD data was made through uo-14 for these 6 months. This board is usable for not only tracker but multi pourpose station controler for the radio amateure. The application expected for this board are satellite tracker, repeater controler,remote sensing,remote base controler,DTMF controler, etc. etc. And the most advantage of this board is that we can develope our own aplications by ourselves using BASIC and if we desire,by mashine language. Furthermore,this CPU has ability to burn EPROM with itself. So, developed BASIC program can be fixed in EPROM on the board. The software written by SM0TER was adapted for the new hardware and tested extensively over several months by beta stations around the world (SM0TER,WA4EJR,JA6FTL,JR1EDE,JA1OGZ,JG6MCG and guys in JA1 area). After running BASIC version, JA6FTL and JG6MCG developed their original tracker code written by C and Assembler language ie. TrakBox v1.00. The TrakBox hardware and software presented in this document are the result of these test. The TrakBox is superior in performance and less costly that other tracking devices commercially available to radio amateurs today. Description The TrakBox is a free standing real time antenna controller. The design is based on the Intel 8-bit embedded controller family of processors. This board will except either an 8052AH- BASIC processor or can be configured to use an 8051 or 8031. |~~~~~~| |~~~~~~~~~| PGM ROM USER ROM |RS-485|----| | | /232C| | 8052-AH | |~~~~~~| |~~~~~~| |~~~~~~| '~~~~~~' | BASIC/ |-----| RAM |----| ROM |----| ROM | |~~~~~~| | 8051/ | | 32K | | 16K | | 64K | |SERIAL|----| 8031 | '~~~~~~' '~~~~~~' '~~~~~~' | PRT | | | 62256 27128 27512 '~~~~~~' | | .FREQ CTRL | | |~~~~~~| |~~~~~~| |~~~~~~| |~~~| | |-----| ADC |----| PPI |----| RTC |---| L | |~~~~~~| | | | 8CH | | 3CH | | SMART| | C | | OPT. |----| | | 10Bit| | 8Bit | | CLOCK| | D | | BUS | | | '~~~~~~' '~~~~~~' '~~~~~~' '~~~' '~~~~~~' '~~~~~~~~~' 8255 * User accessable IO Port 8255 Port-A: buffered IN/OUT Port-B: buffered IN/OUT Port-C: Gate array-IC OUT and non buffered IN/OUT 8052 P1 : 8 bit buffered Option bus All Address/Data/Control signal and CS ADC diode protected 4 channel Direct 8 channel LCD port The 8052AH-BASIC processor has an 8K BASIC interpreter mask programed on the processor chip and is a powerful tool for control applications. All the mathematical functions required for satellite tracking are available. In addition there are 2 serial ports one of which is a duplex port for terminal connection and can be auto configured from 300 to 19200 baud. The second serial port is simplex and can be connected to a printer or to a radio computer port. By setting jumper sw, internal mask ROM mode(BASIC) and external user ROM mode selectable. 8/16/32/64K EPROM can be used as user ROM.
