TPP2W(G2) Platform

Hardware Devices Covered by This Platform

• Size 2 Tibbo Project PCB (TPP2), Gen. 2
• Optionally, with the WA2000 Wi-Fi/BLE add-on module
• Optionally, with the GA1000 Wi-Fi add-on module (no longer supported from TiOS V4)
• Tibbo Project System (TPS) devices based on the TPP2(G2)
• Optionally, with the WA2000 Wi-Fi/BLE add-on module
• Optionally, with the GA1000 Wi-Fi add-on module (no longer supported from TiOS V4)

Memory Space and Key Info

1. The sock.allowedinterfaces property refers to the Ethernet interface as "NET," Wi-Fi as "WLN," PPP as "PPP," and PPPoE as "PPPOE." The sock.targetinterface and sock.currentinterface properties rely on the pl_sock_interfaces enum, whose members differ depending on the platform.

2. Surrounding board hardware and installed Tibbits dictate which GPIO lines must be used as inputs and which as outputs.

3. Default CTS/RTS mapping is different for each serial port:

4. Although the platform itself supports remapping, actual "wires" connecting the system to the GA1000 or WA2000 are fixed and your mapping should reflect this:

Supported Objects, Variable Types, and Functions

• beep — generates buzzer patterns using the onboard buzzer
• bt — responsible for Bluetooth Low Energy (BLE) communications
• button — monitors the onboard setup (MD) button
• fd — manages flash memory file system and direct sector access
• io — handles I/O lines, ports, and interrupts
• kp — scans keypads of matrix and "binary" types⁽¹⁾
• lcd — controls graphical display panels (several types supported)⁽²⁾
• net — controls the Ethernet interface
• pat — "plays" patterns on up to five LED pairs
• ppp — provides access to the Internet over a serial modem (4G, POTS, etc.)⁽³⁾
• romfile — facilitates access to resource files (fixed data)
• rtc — keeps track of date and time
• ser — in charge of serial ports (UART, Wiegand, and clock/data modes)
• sock — socket communications (up to 16 UDP, TCP, and HTTP sessions)
• ssi  — implements up to four serial synchronous interface (SSI) channels, supports SPI, I²C, clock/data, etc.
• stor — provides access to the EEPROM
• sys — in charge of general device functionality
• wln — handles the Wi-Fi interface (requires a GA1000 or WA2000 add-on module to be plugged into the board)

1. On this platform, the kp. object will normally handle the four-key sensor keypad built into the Size 2 Tibbo Project Box With LCD/Keys (TPB2L). The object can also be configured to communicate with an external keypad connected to the TPP2(G2) via Tibbits. Only one keypad can be serviced at a time.
2. On this platform, the lcd. object will only work with the 320x240 TFT LCD with Solomon SSD1963 controller, which is built into the TPS2L.
3. This may be an external modem connected to the TPP2(G2), a 4G (LTE) Tibbit, or a Cat-M1/NB-IoT Tibbit plugged into the board.

This platform supports the standard set of variable types and functions (a.k.a. "syscalls").
