4 / 18 page 4 HSP50016-EV Control Panel Software The HSP50016-EV Control Panel is a graphical user interface for controlling the operation of the HSP50016-EV Board via an IBM PC or compatible. The control panel, shown in Figure 3, supports loading the HSP50016's control words; setting the state of control inputs; and specifying files which serve as the sources and destinations for the HSP50016's data and TAP inputs and outputs. Operation of the control panel software is dependent on the clock source provided to the HSP50016-EV as specified in the clock select portion of the control panel. The HSP50016-EV Control Panel is invoked by typing: DDCCTRL <Enter> Port Configuration Communication between the Control Panel software and the evaluation board requires that the software knows which one of the PC's parallel ports is being used for communication with the HSP50016-EV and which board address the HSP50016-EV has been configured for. The default configuration assumes that LPT1 is being used and that the HSP50016-EV has been configured for a board address of 0. The Port Configuration can be inspected by opening up the port configuration window using the F9 function key. As shown in Figure 4, the window displays the available parallel ports and their addresses. Also displayed are the current port and HSP50016-EV board address being used by the Control Panel software. The current port and HSP50016-EV address are changed by opening up the Port Configuration Window, using the up/down arrow keys to select the desired parameter, and toggling the space bar to change the selection. Proper operation of the control panel software requires that the HSP50016-EV board address specified in the port configuration window matches the address jumpered in the Address Selection Section of the HSP50016-EV’s headers JP6-13. Clock Select The Clock Select portion of the control panel is used to tell the Control Panel software which of four different clock sources is being supplied to the HSP50016-EV. The choices include one of two different software generated clocks (Manual CLK or Port CLK), an oscillator clock provided by the HSP50016-EV (Oscillator CLK), or an externally supplied clock (External CLK). The clock mode selected must be consistent with the Clock Select jumper position in the HSP50016-EV’s headers JP1-3. If either Manual CLK or Port CLK are specified in the Control Panel, the clock select jumper must be inserted in JP3. If either Oscillator CLK or External CLK is specified, the jumper must be inserted in JP2 or JP1 respectively. In Manual CLK mode, single clock pulses are sent to the HSP50016 by depressing the F2 function key. The clock pulse is software generated by setting and clearing the PCCLK bit of the Control Register U16 on the HSP50016-EV. After each clock the HSP50016-EV's data outputs are inspected to see if they are ready to be read. If so, the data is read into the PC for display in the Control Panel. In this mode, file input and output are supported (See File I/O Select Section). In Port CLK mode, a free running clock is sent to the HSP50016. The clock is started and stopped by depressing the F2 function key. The clock pulses are software generated by continually setting and clearing the PCCLK bit of Control Register U16. After each clock the HSP50016-EV's data outputs are inspected to see if they are ready to be read. If so, the data is read into the PC for display in the Control Panel. In this mode, file input and output are supported (see File I/O Select Section). In Oscillator CLK mode, the HSP50016 is supplied with a clock by the oscillator on board the HSP50016-EV. In this mode, the Control Panel can be used for modifying RESET and IQSTRT, the control words, and the data and TAP inputs to the DDC. However, the software is unable to provide file based I/O to the evaluation board since the data rate provided by the oscillator is much greater than that possible through the parallel port of the PC. As a result, the Control Panel disables file based I/O and the display of DDC output in this mode. Operation in External CLK mode is identical to that in Oscillator CLK mode, except that the HSP50016 is supplied with a clock through the 96 Pin DIN connector P1 on the HSP50016-EV. Because this clock is asynchronous to the PC, file based I/O and the DDC output displays are disabled. The clocking mode used by the control panel is indicated by the position of the “check mark” symbol within the Clock Select portion of the Control Panel. A different clocking mode may be selected by positioning the “check mark” symbol in front of the desired clocking mode. The position of the “check mark” is changed by using the cursor keys to move the active window to the desired position and then toggling the space bar to move the “check mark”. File I/O Select The File I/O Select portion of the Control Panel allows the user to specify files which can be used as an input data source or an output data destination for the HSP50016-EV. The input data is loaded on to the input bus prior to the software generated clock and the output data is read from the output bus following the software generated clock. If file based input is selected, the Control Panel software down loads data from the specified file to registers on the HSP50016-EV and clocks the data into the DATA0-15 inputs of the DDC. The Loop Count allows the user to simulate long data streams by repeatedly sending the same input file. If file based output is specified, the software reads the data on the I and Q outputs of the HSP50016 and stores the data in the specified file. The software automatically reads the HSP50016-EV |
