STPM01- QUICK APPLICATION USER GUIDE
1 - USING THE GUI The GUI (Graphical User Interface) provides immediate and easy access to all options you need to set in order to use the STPM01 device. The STPM01 Manager Functionalities are split in five main groups: - Interactive information memo, - Panel Page for Setting and manual Calibration features, - Measured Information Panel to show mainly information about the measurement, - Parameters to set and read relevant data, - Control buttons. The GUI is showed below: Figure 1 : GUI

5 - PARAMETERS The Parameters window allows the user to change some common constants used by the GUI application. Those constants are hardware dependant: 1 Resistor divider (R1 and R2) at voltage input of STPM01 must be set according to the hardware specifications; 2 Current gain (Ai) will change according to the PST bits setting while voltage channel gain (Au) is fixed and cannot be changed; 3 Current sensor sensitivity (Ks/mV/A) must be set according to the particular characteristics of the current sensor used; 4 Value of calibrators (Kup, Kip, Kis). This value changes according to the calibrators value for voltage and current channel; 5 Internal reference voltage, to be set according to the datasheet. Change those constants accordingly, to reflect real state on the STPM01 evaluation board. Figure 5 : Parameters

8 - APPENDIX A 8.1 - Writing data The user can also write data bits in STPM01. Refer to the STPM01 user manual for more detailed information about the meaning of written data bits. The data bits that can be written in STPM01 are: 1 CHVs, CHPs and CHSs, 2 TCs 3 CPHs 4 CRCs 5 NOMs 6 APLs 7 PSTs 8 LTCHs 9 KMOTs 10 ADDG 11 CRIT 12 LVS 13 MDIV 14 RC 15 FRS 16 MSBF 17 FUND 18 ABS 19 Write Configurators section. Refer to the STPM01 user manual for the meaning. Note: Writing a signle bit is possible only for data bits (in this case mode command) located in the Write Configurators group. Figure 9 : Write Button
8.2 - Sending mode command to STPM01 The bits used to change the special modes of STPM01 are located in the group named Write Configurators. Note that those bits are written seperately. Refer to the STPM01 user manual for the meaning of the various operating modes. To write a mode bit check or uncheck the box next to the bit name and press the mouse right button. A new menu will show up with just one option: Write. Click this option to write the selected bit in STPM01. Press the read button to see if writing was successful. Figure 10 : Write to OPT Button

8.3 - Writing to shadow latches To write selected bits to shadow latches make sure that STPM01 is operating in the right mode (please refer to STPM01 user manual). The user can check the operating mode by reading data from STPM01. Select all data bits you want to write in STPM01 and then click the Write button. 8.4 - Writing to OTP Writing selected bits to OTP is similar to writing to shadow latches. STPM01 must operate in the right mode. Note that a high voltage must be available to the STPM01. The high voltage source is selected from: Figure 11 : Write to OPT Button
8.5 - Locking STPM01 The lock button is used for final write of a special bit named TSTD in STPM01. Use with care as no more writing can be done to the STPM01.

9 - APPENDIX B 9.1 - PROGRAMMER In order to use the STPM01 Manager GUI you must use the programmer, whose schematic is shown below: Figure 12 : Programmer
Using the programmer is very easy. After you developed the board (see the PCB below) and connected it to the PC parallel port you have to connect it to the Measurement Board of the Power Meter Kit. Make sure that pin 1 of the cable is connected to the right pin on the board. You can recognize it by the mark printed on the PCB. Switching on the PC and running the STPM01 Manager GUI you will be able to use all functions of the Power Meter Kit. Take care that you must power on the Measure Board if you want to program the OTP inside the STPM01. On the contrary power on the Measure Board is not necessary if you want only to read and write(not OTP write) the RAM inside the STPM01. Figure 13 : PCB, top and bottom layout
