Size 2 Tibbo Project PCB (TPP2)

Introduction

The Size 2 Tibbo Project PCB (TPP2) runs Tibbo OS (TiOS) and is programmable in Tibbo BASIC and Tibbo C.

The TPP2 is perfect for systems with a medium number of I/O lines. The board can optionally control a TFT display and a keypad, so it is suitable for applications requiring a human-machine interface (HMI).

This product can be used as a bare board or assembled into a Size 2 Tibbo Project Box (TPB2). For HMI applications, the board can also be assembled into the TPB2L enclosure, which features a 320x240 TFT LCD and a four-button sensor keypad.

Featuring three tiles for a total of six "M" and six "C" sockets, the TPP2 can implement configurations with up to four simple serial ports, up to 12 relays, or up to 24 opto-inputs, pulse-width modulation (PWM), or open-collector outputs.

The TPP2 is perfect for data collection and automatic identification (AutoID) projects, as well as factory, shop, data center, hotel, and home automation applications. The board contains enough "C" sockets to simultaneously accommodate temperature, humidity, pressure, ambient light, and shock sensors. With the use of appropriate Tibbits, the board can even control legacy IR devices by emulating traditional IR remote controls.

• kp — works with matrix and binary keypads
• lcd — controls the LCD
• net — controls the Ethernet port
• pat — "plays" patterns on up to five LED pairs
• ppp — accesses the Internet over a serial modem (GPRS, etc.)
• pppoe — accesses the Internet over an ADSL modem
• romfile — facilitates access to resource files (fixed data)
