TSgaTe - Smart gateway development platform

The new TSgaTe is a powerful communication platform that enables fast and simple development of M2M solutions, wireless monitoring and remote control applications. Available TST libraries allow easy and quick development of software applications in ANSI C language that take full advantage of the add-on modules.

They also support API librarys through here

specially WIZnet library can be read here

Main technical features of the TSmarT platform are:

• Standard ANSI C programming over proprietary API.
• Available communication interfaces: IEEE 802.15.4 / ZigBee, Wi-Fi (TI CC3000), Wi-Fi (Digi XBee), GPRS, RFID/NFC, GPS.
• Embedded software: real-time multitasking operating system FreeRTOS, TCP/IP, HTTP and Modbus stacks.
• Toolchain based on free and open source tools.
• Powerful low-energy 32 bits microcontroller with an ARM Cortex-M3 core.
• Large amount of memory.
• Sensor interfaces: UART, I2C, SPI, analog and digital I/Os, RS485, USB, Ethernet.
