This board is designed to be interfaced with the XE8000MP board also. Note that the combination of a XE8000MP and any XE8000EVXXX constitutes the ProStart II system. The XE8000EV110 allows the user to access to every pin of the chip, and provides external actuators and indicators such as LEDs and buttons. 2.4 XE8000EV110 components The XE8000EV110 is delivered separately, with 3 XE88LC02 samples. However you need to have the XE8000MP to program these samples. Since one XE8000MP is compatible with the whole XE8000 family, this allows you to have multiple XE8000EVXXX without having to buy another XE8000MP. XE8000EV110 packages contents: 1 XE8000EV110 1 Box 3 Samples 2.5 How the XE8000EV110 helps you XE8000EV110 allows you to: • Create an action on an input port with buttons (note that jumpers can disable this feature). • Reset the circuit. • See an action on an output port with LED (note that jumpers can disable this feature). • Store data in an on board SPI EEPROM. • Interface a RS232 line driver (with the help of the XE8000MP) to the UART peripheral. • Use an on board 32kHz watch Xtal, or an external clock source. • Measure the current consumption of the circuit. • Power the board with three different sources : An external power supply. A button type battery. The ProStart II board. • Create a quick hardware application on an on-board engineering zone. 4 U0502-195 Users Guide XE8000EV110 Evaluation Board for the XE88LC02MI035 2.6 Installing XE8000EV110 hardware 2.6.1 Placing the chip on the ZIF socket The XE88LC02 must be placed with the pin 1 marker aligned with the pin 1 marker of the board. See picture below: Pin 1 marker Figure 1 Position of the chip in the ZIF socket 2.6.2 Using an external power supply To use an external power supply, the user must connect the pins labelled “+” and “-“ (see Figure 2) on the header named “EXT POWER” near the battery carrier with regulated 1.2 to 5.5 Volts power supply. The switch must be in the “on” position. Warning this power source is not protected by a fuse! The user can prevent destroying the board/chip by limiting the current of the power supply source. 2.6.3 Using a button type battery To power the application with a battery, you may place a button battery of the type cr1620 on the carrier (+ on the top, diameter 16mm height 2.0mm). Since the carrier is flexible, the height can vary a little bit. Warning this power source is not protected by a fuse! 2.6.4 Using the ProStart II as power supply and programmer Please refer to ProStart II user guide to use the XE8000EV110 with the ProStart II as a power supply or a programmer. Note : When the ProStart II (XE8000MP) is connected, all the other supply sources are bypassed, the default supply of the ProStart II (XE8000MP) is 3.0 Volts and the programming voltage is 5.0 Volts. 2.6.5 Using an external clock source To use an external clock source, the user must disconnect the on onboard xtal by removing the br1 jumper, and place it’s own source on the pin XIN on the header. (see Figure 3) 2.6.6 Measuring the circuit consumption To measure the consumption of the XE88LC02, the user must remove the jumper named br_consumption and place an amperemeter between these two points. 2.6.7 How to use the on-board EEPROM To use the on board EEPROM, place the jumpers br4 to br7, and for the software please check on our web site for the technical note TN8000.14 on http://www.xemics.com/internet/support/download 5 U0502-195 Users Guide XE8000EV110 Evaluation Board for the XE88LC02MI035 3 ELECTRICAL SPECIFICATIONS AND HARDWARE DESCRIPTION 3.1 Introduction This chapter gives you a view of the main characteristics of the XE8000EV110 hardware. 3.2 Hardware layout Jumpers that allow the user to External power supply pins disconnect the ports from LED’s + - Connector for LCD display Engineering Battery socket (CR1620 size) area On / Off switch fot the battery or external power supply Jumper that allows to measure the Microcontroller comsumption Jumper for an external clock source EEPROM supply jumper Connector to the ProStartII Jumpers to disconnect the EEPROM EEPROM Reset button Leds on I/O ports Ground bridge for probes Jumpers that allow the user to Buttons on input disconnect the port from buttons port Figure 2 Board elements PORT A Acquisition XE8000 BITS chain signals signals PORT D1 PORT B BITS BITS PORT D2 SPI BITS signals Figure 3 Detailed view of the header 6 U0502-195 Users Guide XE8000EV110 Evaluation Board for the XE88LC02MI035 3.3 LCD Board XEMICS provides a LCD board with each EV110 in order to quickly set up an application using the LCD driver peripheral. 3.4 Hardware layout of the LCD board LCD Display MUX 4 / 8 digits LCD connector to interface EV110 board LCD external capacitors Figure 4 LCD board hardware layout 3.5 LCD connector Figure 5 EV110 LCD connector (top view) Figure 6 EV110 LCD connector (side view) 7 U0502-195 Users Guide XE8000EV110 Evaluation Board for the XE88LC02MI035 3.6 LCD specifications The LCD provided has the following specifications: Device name : VIM828 Multiplex : 4x Digits : 8 Digit height : 8.9mm Segments/digits : 14 Supplier : http://www.varitronix.com/ 3.7 LCD display mechanical specifications Figure 7 LCD display mechanical data 8 U0502-195 Users Guide XE8000EV110 Evaluation Board for the XE88LC02MI035 3.8 Segments mapping a j f b g i k h l n e c m dp d Figure 8 Segments naming convention LC02 registers bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 Digit 1 RegLcdData0 1d 1e 1f 1dp 1c 1b 1a RegLcdData1 1n 1k 1i 1j 1m 1l 1h 1g Digit 2 RegLcdData2 2d 2e 2f 2dp 2c 2b 2a RegLcdData3 2n 2k 2i 2j 2m 2l 2h 2g Digit 3 RegLcdData4 3d 3e 3f 3dp 3c 3b 3a RegLcdData5 3n 3k 3i 3j 3m 3l 3h 3g Digit 4 RegLcdData6 4d 4e 4f 4dp 4c 4b 4a RegLcdData7 4n 4k 4i 4j 4m 4l 4h 4g Digit 5 RegLcdData8 5d 5e 5f 5dp 5c 5b 5a RegLcdData9 5n 5k 5i 5j 5m 5l 5h 5g Digit 6 RegLcdData10 6d 6e 6f 6dp 6c 6b 6a RegLcdData11 6n 6k 6i 6j 6m 6l 6h 6g Digit 7 RegLcdData12 7d 7e 7f 7dp 7c 7b 7a RegLcdData13 7n 7k 7i 7j 7m 7l 7h 7g Digit 8 RegLcdData14 8d 8e 8f 8dp 8c 8b 8a RegLcdData15 Table 1 LCD display vs XE8000 registers mapping Pin No. Segment Pin No. Segment Pin No. Segment 1 , , , COM 4 13 3I, 3J, 3K 3N 25 3H, 3G, 3L, 3M 2 , 8F, 8E, 8D 14 , 2F, 2E, 2D 26 4A, 4B, 4C, 4DP 3 8I, 8J, 8K, 8N 15 2I, 2J, 2K, 2N 27 4H, 4G, 4L, 4M 4 , 7F, 7E, 7D 16 , 1F, 1E, 1D 28 5A, 5B, 5C, 5DP 5 7I, 7J, 7K, 7N 17 1I, 1J, 1K, 1N 29 5H, 5G, 5L, 5M 6 , 6F, 6E, 6D 18 , , COM 3 , 30 6A, 6B, 6C, 6DP 7 6I, 6J, 6K, 6N 19 COM 1 , , , 31 6H, 6G, 6L, 6M 8 , 5F, 5E, 5D 20 1A, 1B, 1C, 1DP 32 7A, 7B, 7C, 7DP 9 5I, 5J, 5K, 5N 21 1H, 1G, 1L, 1M 33 7H, 7G,, 7L, 7M 10 , 4F, 4E, 4D 22 2A, 2B, 2C, 2DP 34 8A, 8B, 8C, 8DP 11 4I, 4J, 4K, 4N 23 2H, 2G, 2L, 2M 35 8H, 8G, 8L, 8M 12 , 3F, 3E, 3D 24 3A, 3B, 3C, 3DP 36 , COM 2 , , Table 2 Manufacturers LCD segment mapping 9 U0502-195 Users Guide XE8000EV110 Evaluation Board for the XE88LC02MI035 4 TROUBLESHOOTING 4.1 Introduction This section is intended to help the XE8000EV110 users to perform basic hardware debugging. 4.2 Highlights This chapter contains the following points: • XE8000EV110 functionality • XE8000EV110 hardware 4.3 XE8000EV110 functionality The software that should use the Xtal peripheral seems to be locked. Possible causes : 1 The jumper br1 is removed 2 You disturb the xin and xout lines with an oscilloscope probe. 3 The Xtal is not correctly soldered on the board. 4 The Xtal is damaged. The programme that should use the EEPROM interface or another SPI device is unable to communicate. Possible cause : 1 The LED jumpers of the ports used are connected 2 The EEPROM jumpers (br5&6)are removed 3 The EEPROM power jumpers is removed When using the ProStart II (XE8000MP) as power supply, the VDDA seems to be unstable. Possible causes : 1 The PortB 7 is not used as UART RX and the RS232 line driver creates an ouput conflict, simply remove the RS232 cable from the ProStart II (XE8000MP) and the RS232 output will go to High Z. 2 The power consumption of your application is above 500mA 4.4 XE8000EV110 hardware The board presents a short circuit between VDDA and GND. Possible causes : 1 The battery carrier has been damaged and the + contact touches the - : just put a piece of paper between the two contacts 2 If you are measuring a signal on the board, be careful to not use the ground connection on the headers : There is a more accessible ground near the PA7 button. The power supply of the battery is not present on the VDDA line. Possible causes : 1 The power switch is in the wrong position, to use the battery the switch must be off. 2 The board is connected to a XE8000MP, in this case user power supplies are bypassed. The LCD display doesn’t display all the digits Possible causes : 1 The connector is weak, try to move the board a little bit. 10 U0502-195 XEMICS Users Guide XE8000EV110 Evaluation Board for the XE88LC02MI035 5 SCHEMATICS Figure 9XE8000EV110 Schematic 11 U0502-195 Users Guide XE8000EV110 Evaluation Board for the XE88LC02MI035 ©XEMICS 2005 All rights reserved.
