RF2500T board and pins

[astuder]

Adding support for eZ430-RF2500T w/ MSP430F2274.

The MSP430F2274 is part of the MSP430x2xx family and peripherals are similar to MSP430G2553.

Alternative to pull request #309, I unknowingly developed the same thing :) However my version has the following differences:

• this one only includes updates to boards.txt, pins_energia.h and a minor fix to analogWrite()
• pin numbering according to silkscreen on PCB and schema in user guide (unlike 309)
• based on Energia fork from 3/16, i.e. uses new format for analog pin definition
• slightly different numbering for LED, debug serial etc.
• includes visual reference based on Rei Vilos template

Tested:

• Serial (9600)
• SPI
• digital write to both LEDs
• digital read of push button
• analog read of temp sensor
• analog write on all valid pins (unfortunately not available for LEDs)
• delay

What would be necessary in order to adequate this to the merging guidelines?

A major revision of Energia is available. It features the Board Manager and the Library Manager, based on Arduino 1.6.10.

This makes adding new boards much easier. For the complete reference, please refer to

• Arduino IDE 1.5 3rd Party Hardware Specification, and
• Arduino IDE 1.5: Library Specification.

New Board and Library Manager!

Energia 18 (aka Energia 1.6.10E18) is based on the latest and greatest Arduino IDE. This release features the new board (core) / library manager. Default the Energia installation comes with support for the MSP430. Other cores such as TivaC, CC3200, MSP432 can be installed through the board manager by selection Tools->Board->Board Manager. For more details on how to install additional cores/boards see the board manager guide guide.

The cores included in the board manager are: MSP430, MSP432 (MT, TI-RTOS based multitasking), CC3200 and TivaC. The CC3200 (MT) TI-RTOS based multitasking based core will be made available in the near future through the board manager. CC2650 has been removed from Energia due to the lack of BLE support that could not be enabled because of licensing issues with the BLE stack.
