Gen 2. performance highlights

The TPP2(G2) is a high-performance upgrade to the original TPP2 board. Here is a list of important improvements:

32-bit architecture (vs. 16-bit architecture of the TPP2).

5 to 80 times better performance, depending on the calculations and variable types.

7 times faster GPIO manipulation.

3 times larger available user SRAM (66KB vs. 22KB).

1.5-3.0 times faster graphics.

2 times larger flash memory (1MB for TiOS/code + 1MB for the file system vs. 1MB total for TiOS, code, and file system).

2.2 times lower power consumption (100mA vs. 220mA).

The ability to update TiOS firmware and compiled Tibbo BASIC/C app over-the-air (this requires the WA2000 and an iOS or Android device).

 

Introduction

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

TPP2(G2) 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. For HMI applications, the board can also be assembled into the TPB2L box, which features a 320x240 TFT LCD and a 4-button sensor keypad.

Featuring 3 tiles for a total of 6 "M" and 6 "C" sockets, the TPP2(G2) can implement configurations with up to four simple serial ports, up to 12 relays, or up to 24 opto-inputs, PWM, or open-collector outputs.

The TPP2(G2) is perfect for data collection and 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.

Hardware features

32-bit architecture.

Powered by Tibbo OS (TiOS).

10/100BaseT auto-MDIX Ethernet port (automatic detection of "straight" and "cross" cables).

Optional Wi-Fi interface (requires the WA2000 add-on module).

Optional BLE interface (requires the WA2000 add-on module).

Optional GPRS interface (requires Tibbit #47).

3 tiles with 24 general-purpose I/O lines:

 - 6 sockets for Tibbit modules;

 - 6 sockets for Tibbit connectors;

 - 1 extra socket for Tibbit #37;

 - 4 Tibbit module sockets have UART capability:

     - Baudrates of up to 460,800bps;

     - None*/even/odd/mark/space parity modes;

     - 7*/8 bits/character;

     - Full-duplex mode with RTS/CTS and XON/XOFF flow control;

     - Half-duplex mode with direction control;

     - Encoding and decoding of Wiegand and clock/data streams.

 - Each module socket has an interrupt capability;

 - 1 module socket has PoE capability.

 - 4 remappable synchronous serial ports with SPI and I2C modes.

Onboard buzzer.

Connectors for the TFT LCD and sensor keypad of the TPB2L.

RTC with a backup supercapacitor.

66KB SRAM for Tibbo BASIC/C variables and data.

1MB flash for TiOS and application code.

Additional 1MB flash for the hardened fault-tolerant file system.

2048-byte EEPROM for data storage.

Eight onboard LEDs:

 - Green and Red main status LEDs;

 - Yellow Ethernet link LED;

 - Five blue LEDs (for Wi-Fi signal strength indication, etc.).

Software-controlled PLL allows selecting full, medium, or low speed.

Reliable power-on/ brown-out reset circuit.

Power: 100mA @ 3.3V (100Base-T mode, full speed).

Dimensions (LxW): 94 x 94mm.

Operating temperature range: -40 ~ +70C.

Firmware is upgradeable through:

oThe serial port;

oEthernet LAN; or

oOver-the-air (requires the WA2000 and an iOS or Android device).

Tibbo BASIC/C application can be debugged through the Ethernet LAN.

CE- and FCC-certified.

 

* The TPP2(G2) does not support the combination of 7 bits/character mode and the "none" parity mode.
