Description

isoSPI 2-Wire Serial Analyzer

Demonstration circuit 1907A is an isoSPI™ analyzer board.

isoSPI is a bi-direction 2-wire serial interface with high noise immunity and the ability to communicate over long cables. Because isoSPI is a proprietary serial interface with unique signaling, the DC1907 board is available to help users develop systems using the isoSPI serial link. The DC1907 can be connected across the two wires of an isoSPI link to decode the isoSPI communication and

operation DescriptionThe DC1907 implements an isoSPI receiver that can connect across a 2-wire isoSPI data link. The DC1907 does not terminate the isoSPI lines and should represent a minimal load to an operating isoSPI serial link. The DC1907 decodes the isoSPI data using comparators to check for minus 1 and plus 1 signals and an FPGA to check pulse timing. After pulses have been decoded the FPGA outputs the serial data in a standard SPI format onto the logic analyzer header JP13 for analysis with an oscilloscope or logic analyzer. The FPGA also sends the

detected isoSPI data to an onboard microcontroller(MCU) that formats the data and transmits it to a PC. The MCU connects to the PC over a USB link. Software is available that can decode the data sent from the DC1907 to the PC. The software is capable of displaying data and data log-ging. For LTC®6804 battery management applications the software is capable of decoding unique device commands and checking the command packet error codes(PEC) to aid program development.

LeD summary

JP1 VIN - EXT/USB

• Ext: Set to EXT to power the board from an external 5V supply.

• USB(default): Set to USB to power the board from a PC’s USB port (no external supply required).

JP 2, 4, 6, 7 - VTH Jumpers

Note that all four of these jumpers must be connected the same (i.e. connected to VTH1 or VTH2).

• VTH1: Use this setting for an isoSPI link with Ibias between 160µA and 1mA (default setting).

• VTH2: Use this setting for an isoSPI link with Ibias between 100µA and 160µA.

ON: Indicates the state of the connection between the PC and the DC1907 MCU. If the LED is blinking, the MCU is waiting for the PC to connect. If the LED is solid this means the MCU is connected to the PC.

TX: Indicates when data is being sent from the MCU to the PC. The LED turns on when the MCU is communicating with the PC.

ER: Indicates a full transmit buffer. If this LED is ON the PC will most likely have lost some of the isoSPI transmit-ted data.

Reset: Can be used to reset the MCU. This button is useful if the MCU appears to be non responsive and data is not being received by the PC.

Boot: This button is used to program the MCU. Do not use.

• Connect the DC1907 to a USB port and wait for new hardware installer to open.

• Do not allow windows to search for the driver automatically. Select the install from a list or specific location option, then navigate to the folder where the DC1907 software was installed. This will default to either C:\Program Files\LTC\DC1907_Generic or C:\Program Files\LTC\DC1907_LTC6804 depending on which version of the software was installed. If both versions are installed, the driver can be found in either location.

• Windows should now find the DC1907.inf file and install the drivers.

Windows 7/XP

• Connect the DC1907 to a USB port and Windows will automatically begin it's driver installation process. It will fail after a short time.

• From the Start Menu, open the Control Panel.

• In the Control Panel, navigate to System and Security. Then, click on System and in the System window open the Device Manager.

• Look under Ports (COM & LPT). There should be an open port named DC1907_isoSPI_Analyzer (COMxx)

• Right click on the DC1907_isoSPI_Analyzer (COMxx) port and choose the Update Driver Software option.

• Next, choose the Browse my computer for Driver software option.

• Navigate to and select the DC1907's driver file, named DC1907.inf, located in the folder that the DC1907 software was installed into. This will default to either C:\Program Files(x86)\LTC\DC1907_Generic or C:\Program Files(x86)\LTC\DC1907_LTC6804 depending on which version of the software was installed.

• Windows will finish up the driver installation from there.

Ltc6804 software operationThe DC1907 isoSPI monitoring software is easy to use. When you open the software you will see the window shown in Figure 3.

The software will automatically try to connect to the at-tached DC1907. Once the board connects, the status box will become green and indicate connected. The ON LED on the DC1907 should be blinking while the software is trying to connect. Once the software has connected, the LED will turn solid. If the board does not connect, make sure that the ON LED is blinking. If it is not blinking press the reset button located on the DC1907 demo board. Once the LED is blinking, manually select the comm. port in the

software and click the connect button. Generally, if there is more than one port listed the DC1907 will most likely be the highest numbered port. The connection status is also indicated on the DC1907 board by the ON LED.

Once the software has connected (Figure 4) it will begin to display data decoded by the DC1907. The software displays LTC6804 data separated into IC data and com-mand data. The IC data is made up of the master out slave in (MOSI) row and the master in slave out (MISO) row. Data is displayed in hex format. The LTC6804 command data is decoded and the software will check to make sure the transmitted command PEC matches a calculated PEC.
