EM200

Introduction

The EM200 is a BASIC-programmable embedded module that can serve as a networking coprocessor of your "connected" device. The firmware of the EM200, called TiOS, features a virtual machine that executes your application written in Tibbo BASIC/C. The EM200 has no pre-defined functionality whatsoever -- programmability in Tibbo BASIC/C means that you can create your own unique EM200 applications!

Each hardware faculty of the EM200 is supported by a sophisticated programming "object" which you interact with from the Tibbo BASIC/C application. Together, objects form a "platform" that defines EM200 capabilities from the programming point of view.

The EM200 platform, along with the Tibbo BASIC/C language and TIDE software is described in the TIDE, TiOS, Tibbo BASIC, and Tibbo C Manual.

Hardware features

• Very compact dimensions (32.1 x 18.5 x 7.3 mm).

• One 100/10BaseT Ethernet port. Standard Ethernet magnetics are NOT integrated into the module.

• One serial ports (CMOS-level):

• The port can work in the UART, Wiegand, or clock/data mode. Support of Wiegand and clock/data interfaces is a unique feature of Tibbo devices.

• UART supports:

• baudrates of up to 115'200bps;

• none/even/odd/mark/space parity modes;

• 7/8 bits/character modes;

• full-duplex mode with optional flow control, half-duplex mode with automatic direction control.

• 128KBytes of flash memory. First 64KB are used to store device firmware (TiOS). The rest is available to your Tibbo BASIC/C application.

• 2KBytes of EEPROM memory.

• 9 general-purpose I/O lines.

• The following lines are additionally available:

• 2 lines for green and red status LED control;

• 2 lines for Ethernet status LED control;

• 1 line to connect the "system" button.

• External reset input.

• Device firmware can be upgraded through the serial port or Ethernet.

• Tibbo BASIC/C application can be uploaded and debugged through the Ethernet.

Programming features

• The following data types and related functions are supported:

• Byte and char (occupy 1 byte);

• Integer (word) and short (occupy 2 bytes);

• String, can be up to 255 characters long;

• The following function groups are supported:

• Conversion to and from strings: asc, chr, val, str, left, mid, right, len, instr, etc. (16 function in total);

• The following objects form the EM200 platform:

• Sockets (sock.) object -- supports up to 16 simultaneous UDP or TCP connections, or HTTP sessions;

• Ethernet (net.) object -- controls Ethernet interface;

• Serial (ser.) object -- supports UART, Wiegand, and clock/data modes;

• Input/output (io.) object -- handles I/O lines;

• EEPROM (stor.) object -- facilitates access to the EEPROM memory;

• ROM data (romfile.) object -- provides access to the fixed ("ROM") data of your Tibbo BASIC/C application;

• LED pattern (pat.) object -- "plays" patterns on Green and Red Status LEDs;

• System button (btn.) object -- handles special system (MD) button;

• System (sys.) object -- controls general device functionality.
