OpenTag Platforms

In OpenTag parlance, a Platform is a combination of a computing element, a memory, and non-radio I/O. Typically, it is a microcontroller, but it could also be a higher level I/O standard, such as POSIX. OpenTag can be ported to many kinds of platforms, although it usually needs at least 1KB SRAM and at least 12KB ROM (Flash). More typically, 4DMIPS + 2KB SRAM + 32 KB Flash + Masked Interrupt Controller is a decent, minimum-spec platform for implementing most (if not all) OpenTag features. Adding more DMIPS, RAM, ROM, or a better interrupt controller (e.g. NVIC) enables more advanced applications, but it does not necessarily improve the way OpenTag runs itself.

Client and Server Platforms

OpenTag has a client-server architecture, where all devices that actually talk DASH7 are servers. The client is a control interface that can connect to a server. OpenTag can be built for client or server, and the platforms supported by client or server may differ. For example, POSIX is a very common client platform, but it is not likely to be used as a server, unless it is being used as a simulator.

Table of Supported Platforms

An OpenTag server is typically run on bare metal on a microcontroller (ARM Cortex M3, MSP430, etc), and a client is typically run on some sort of more formal OS. However, it is possible to port the server to other kinds of Real Time OS'es too, but these ports have not yet been developed. I expect that ports for certain RTOSes like ChibiOS, TinyOS, FreeRTOS, RTLinux, etc, will end up being developed by the community in time.

The “official” supported toolchains (e.g. IDEs) are also listed in this table. Like with the platforms themselves, OpenTag is not limited to these toolchains, they are just the ones that have been verified to work.
