INTRODUCTION:

This board allows you to easily develop Ethernet connectivity applications.It has everything you normally would need for such applications: powerrelays which you can command through web interface, LCD display whichwill display messages you fill in web forms, analogue inputs for connectionto sensors, digital optoisolated inputs, trimmer potentiometer, temperaturesensor, Ethernet connector. With this board you can easily automate yourhome and then control and monitor it from any point in the world viaInternet. An extension connector is available so you can connect custommade hardware to the board. The PIC18F97J60 has 128KB Flash programmemory and there is external 1Mbit (128KB) flash memory for data storage.The on board DC/DC converter makes this board very tolerant to theexternal power supply which could be in 9-25V DC or 7-18V AC range. Thebridge rectifier on the input allows AC and DC adapters to be used andmakes power supply polarity problems go away.

BOARD FEATURES:

- PIC18F97J60 microcontroller with embedded Ethernet MACand PHY and 128KB Flash programming space - 1Mbit on board serial flash for web pages storage - ICSP/ICD connector for programming and debugging with PIC-ICD2 and PIC-ICD2-POCKET. - Temperature sensor - Trimmer potentiometer connected to analogue input - Two relays 10A/250VAC - Four optoisolated digital inputs - Twelve analogue inputs on terminal block - Two buttons - LCD16x2 with backlight - RS232 interface - Ethernet interface - Complete web server and TCP-IP stack support as perMicrochip's open source TCP-IP stack - Terminal block for power supply works with 9-25 VDC powersupply - Extension header to connect to other boards - Dimensions 120x108 mm (4.72x4.25")

ELECTROSTATIC WARNING:

The PIC-MAXI-WEB board is shipped in protective anti-static packaging.The board must not be subject to high electrostatic potentials. Generalpractice for working with static sensitive devices should be applied whenworking with this board.

BOARD USE REQUIREMENTS:

Cables: Depends on the used programming/debugging tool. It couldbe 1.8 meter USB A-B cable to connect PIC-ICD2-POCKET or PIC-ICD2 toUSB host on PC or RS232 cable for PIC-ICD2-TINY and PIC-ICD2. You will

Page 2

need a serial cable if not for programming, than for configuring the board.You will also need a LAN cable.

Hardware: Programmer/Debugger –Olimex programmers are applicable,for example PIC-ICD2, PIC-ICD2-POCKET, PIC-ICD2-TINY orother compatible programming/debugging tool.

!!!Warning!!! When you want to program this microcontroller with PIC-ICD2, PIC-ICD2-POCKET or PIC-ICD2-TINY, beforeconnecting the programmer to your target board, you shouldfirst connect the programmer to your computer and openMPLAB. There, first from menu Configure – Select Device –choose the microcontroller you are about to program, then frommenu Programmer – Select Programmer – choose MPLAB ICD2, wait while MPLAB is downloading operation system, andafter ICD2 is connected – check in menu Programmer –Settings – Power – there is option – Power target circuit fromMPLAB ICD 2 – this option should be forbidden, you could notselect it. Now it is safe to connect the programmer to yourtarget board.

Software: PIC-WEB is tested with MPLAB IDE v.7.62 + MPLAB C18 Ccompiler. It is possible that the stack might not functionproperly if used with later versions of MPLAB IDE.You will also need a terminal program configured at 19 200bps, 8N1 and no flow control.

BOARD LAYOUT:

POWER SUPPLY CIRCUIT:

PIC-MAXI-WEB can take power only from power connector PWR, where (9-12) VDC or (6-9) VAC external voltage source has to be applied.

The board power consumption is about 200 mA with all peripherals andMCU running at full speed, relays and LEDs on and working Ethernetconnection.

RESET CIRCUIT:

PIC-MAXI-WEB reset circuit is made with RC group R20 – 10k and C31 –100nF. Serial resistor R21 – 330Ω is used to prevent fast C31 charge anddischarge when PIC18F97J60 is being programmed. Manual reset is possible by the RESET button.

CLOCK CIRCUIT:

Quartz crystal 25MHz is connected to PIC18F97J60 pins OSC1 (CLK1) andOSC2 (CLKO). Internal PLL circuit can multiply this frequency up to41MHz.

32.768 KHz quartz crystal is connected to PIC18F97J60 pins T1SO andT1OSI for its internal Timer1.

Page 9

JUMPER DESCRIPTION:

5V_E enables 5V supply for LCD and relays.Default state closed (shorted).

3.3V_E enables 3.3V supply for PIC18F97J60 and all other devices. Default state closed (shorted). 3.3V is also available to EXT-1,

so if you want to connect external backup battery to thePIC18F97J60 this jumper should be opened and the externalbattery to be connected to EXT-1 pin.

#SS1/#SS2 chip select for U5 (AT45DB011) serial flash. Default position is selected to be #SS2 in compatibles with Microchip

software but user can change it in its own application. Default state closed (shorted)

INPUT/OUTPUT:

Two User buttons with names BUT1 and BUT2 – connected toPIC18F97J60 pin 8 RB3/INT3/ECCP2(1)/P2A(1) and pin 6 RB1/INT1;

One analog trimmer AN_TR – connected to PIC18F97J60 pin 33RA2/AN2/VREF-;

Thermistor TH1– connected to PIC18F97J60 pin 32 RA2/AN2/VREF+;

Three LEDs – LD0 (yellow) – connected to PIC18F97J60 pin 49 RJ0/ALE ,LD1 (red) – connected to PIC18F97J60 pin 50 RJ1/#OE, LD2 (red) –connected to PIC18F97J60 pin 66 RJ2/#WRL;

Four opto isolated digital inputs IN1-IN4;

Four red LEDs – LED1, LED2, LED3, LED4 for every digital input;

Two green LEDs – LED5, LED6 – for the relays;

Power supply red LED with name PWR_LED – indicates that 3.3V powersupply is available

Twelve analog inputs X1-X6;

LCD Display - SC1602A - 16 characters x 2 lines.
