Slim-Link® Web Server-Controller

June 2001

Micro-Controller incorporates Web-Enabled, Real-time Operating System

DESCRIPTION

The Slim-Link family of Web Server-Controller products

provides the ideal core technology for Internet enabled

instruments and control systems. The Slim-Link Web Server

Controllers are based on a 40 MHz AMD186ES micro-

controller and feature MicroRTOS, a web enabled, real-time

operating system developed spedifically for control system

applications. MicroRTOS is embedded into each Slim-Link

Web Server-Controller product with no additional cost or

licensing fees.

MicroRTOS

MicroRTOS was created to simplify the process of designing a

web enabled instrument or control system.

This is

accomplished by integrating a Preemptive Real-time Kernel,

thin Web Server, and TCP/IP Stack into the fully-functioning

operating system. The designer can then concentrate on the

design of his application rather than integrating source codes

from disparate applications. Three editions of MicroRTOS are

available to support your application; the Basic edition, PPP

Client Edition with Point-to-Point protocol for dial out

applciations and the PPP Server Editon with Point-to-Point

protocol for in bound dial-up applications.

Slim-Link^®Server

Slim-Link^®Server Local Area Network Connection

The Slim-Link^®Server integrates a 10Base-T connection.

An AMD AM79C961A Ethernet Controller is linked to

the AMD186 main controller to handle the local area

network interface. The AM79C961 provides both the

Ethernet Control functions and 10Base-T transceiver

facilities.

The AM79C961A operates in Bus Master mode

permitting it to directly address all memory locations. The

fixed Ethernet Physical address is stored in an on-board

EEPROM with other configuration data.

The integrated AM79C961A supports an IEEE 802.3 or

ANSI 8802-3 compliant 10Base-T network connection.

The ethernet controller handles all data framing,

addressing and error detection tasks, and manages

collision handling and avoidance.

Slim-Link^®Server Serial Ports

The Slim-Link^®Server includes a pair of serial ports for

local communications. These ports come directly from

the AM186 controller. Serial Port B supports hardware

flow control lines as well as transmit and received data.

Serial Port A supports only transmit and received data.

Serial Port B

Serial Port B corresponds to Serial Port 0 of the AM186

micro-controller. Serial Port B includes hardware flow

control lines RTS (Request to Send) and CTS (Clear to

Send) as well as TXD (Transmit Data) and RXD

(Received Data). All signals are active low.

Serial Port A

Serial Port A corresponds to Serial Port 1 of the AM186

micro-controller. Serial Port A includes only the TXD

(Transmit Data) and RXD (Received Data) signals.

These signals are active low.

The hardware flow control lines regulate the flow of data

between the Slim-Link^®Server and its serial peripheral.

When both devices can receive data the RTS and CTS

lines remain active. The Slim-Link^®Server should keep

RTS active as long as it can accept data from the

peripheral equipment. It should drop RTS to signal the

peripheral equipment that it cannot accept data on RXD.

The peripheral equipment will likewise manipulate CTS

to indicate when it is unable to accept data on TXD.

Serial Port A does not support Hardware Flow Control.

In-band flow control should be used instead. When using

in-band flow control, predefined XON and XOFF

characters serve as flow control signals from the

controller and peripheral. The equipment places an

XOFF character in the data stream when it can no longer

accept data. An XON character is sent when data traffic

can again be accepted.

AWC86A Analog Outputs

The AWC86A includes two Analog Output pins. These

outputs are supported by a 12-bit internal digital to analog

convertor within the Slim-Link Server. Three of the

AM186 Programmable Input/Output lines are used to

support this function.

The three signals which control the integral Digital to

Analog Convertor are PIO3, PIO26 and PIO29. Serial

data is presented to the digital to analog convertor on

PIO26. The serial data clock is presented by PIO3. PIO3

controls the flow of data within the Digital to Analog

Convertor. PIO3 low permits the serial data to be clocked

into the input shift register. When PIO3 is high data is

transferred from the shift register to the DAC Registers

and updates the DA0 AND DA1 outputs.

Digital to Analog Convertor

The Digital to Analog Convertor converts 24-bit serial

data bytes into two analog output signals. The serial data

is transmitted synchronously from the AM186 controller

to the Digital to Analog Convertor. The first 12 bits define

the level at DA0; the remaining 12 bits define the level at

DA1. The maximum output voltage on either analog

output is 4.095 volts, the Least Significant Bit equals 1

millivolt.

AWC86A Analog Input Lines

The Slim-Link^®Server is available with 8 Analog Input

pins, AWC86A only. These inputs feed into a common

12-bit Analog to Digital Convertor, ADC. Three of the

Programmable Input/Output lines from the AMD186

support these analog inputs.

Analog Channel Selection

As mentioned above, a 4-bit word is issued by the

AMD186 controller to select the analog channel. The

logic table below shows how each channel is addressed.

The AWC86A multiplexes all eight analog inputs into a

single ADC under the control of the AMD186 controller.

With Programmable Input/Output 2 high the AMD186

controller sends the 4-bit multiplexor address on

Programmable Input/Output 26. When Programmable

Input/Output 2 is low, serial data flows from the ADC to

the AMD186 controller on Programmable Input/Output

26. The synchronizing clock for the data is provided by

the AMD186 on Programmable Input/Output 29.

Slim-Link^®Server

AWC86A Real-Time Clock

The AWC86A version of the Slim-Link^®Server

incorporates a Real-Time Clock. The Real-Time Clock

tracks month, date, year, day, hours, minutes and seconds.

Applying a battery voltage to Pin 24 permits the Real-

Time Clock to maintain the time when power is shut down

to the AWC86A.

Hours: Register Address 00010

This register stores the hour count in BCD form. Bit seven

selects whether a 12-hour or 24-hour clock will be used.

A 1 selects a 12-hour clock. When a 12-hour clock is

used bit 5 stores AM/PM status.

Date: Register Address 00011

The Real-Time Clock interfaces to the AM186 controller

through Programmable Input/Output lines 15, 26, and 29.

PIO15 controls the Real-Time Clock Reset. Reset must

be high during serial communications and should be held

low otherwise. PIO26 provides the serial data path to the

Real-Time Clock. PIO29 provides the serial clock which

synchronizes the data exchange with the AM186. Data

sent to the Real-Time Clock is read on the Trailing edge

of the serial clock; data is sent from the Real-Time Clock

on the failing edge of the serial clock. Clock frequency

should be no greater than 2 MHz.

This register stores the Date in BCD form.

Month: Register Address 00100

This register stores the month in BCD form.

Day: Register Address 00101

This register stores the day in BCD form.

Year: Register Address 00110

This register stores the year in BCD form.

Write Protect Register:

Register address 00111 provides write protection for the

Clock/Calendar Registers. New values cannot be written

into these registers if bit seven of the Write Protect

Register is set.

The Real-Time Clock stores Clock/Calendar data in seven

registers. Other registers store control information and

access a thirty byte RAM. Data can be read or written

from the Real-Time Clock one register at a time or

multiple registers may be addressed in a single burst.

Trickle Charge Register:

The AWC86A can charge the battery used to backup the

Real-Time Clock. The Trickle Charge Register, address

0100, controls the function. The bit-mapping of this

register is shown below. The remaining bits set the

maximum charging current as shown below.

Command Byte:

A command byte precedes each data transfer in the Real-

Time Clock. The bit mapping of the 8-bit command byte

is shown below.

Clock/Calendar Registers and the Write Protect Register

to be addressed with a single, continuous data string.

Seconds: Register Address 00000

This register stores the second count in BCD form. The

Clock Halt Flag is stored in bit seven. When this flag is

set the clock’s oscillator is stopped.

RAM Burst Register:

The RAM Burst Register, address 11111, allows all thirty

of the RAM registers to be addressed with a single,

continuous data string.
