How to Add Support for MSP430G2955

[rei-vilo]

How difficult / easy would it be to add support for the MSP430G2955 on Energia?

Apart the MSP430G2553 which comes in DIP package, the MSP430G2955 is easy to solder on a TSSOP to DIP adapter. It provides more Flash and RAM.

Thank you!

Adding support for the G2955 would be quite easy, the question is more the pin map which should be used as Energia is centered around a Board/Launchpad on the pin map.

[rei-vilo]

We could stick with the pin numbering scheme of the MCU, as there is no LaunchPad available.

just pushed a initial version to the G2955_support branch

Thank you very much, @StefanSch. I'll a try and let you know!

Thanks @StefanSch for adding support for the G2955. One question @rei-vilo. Should we put this in the boards menu for all or hide en you will in unhide it for your purposes? Either works for me.

I'm using an old MSP430G2 LaunchPad rev 1.4 as programmer-debugger.

Here is the standard Blinky sketch.

~However, there seem to be an issue with the clock. delay(10) lasts 138 ms and delay(100) lasts 1324 ms.~ Clock works fine now.

@robertinant I would suggest to include it in the boards menu for all. The pins map is attached below.

So far:

• Blink LED works on P1_0 = RED_LED
• Serial works
• SPI to Nokia 5110 screen works

To be continued...

G2955 connected to Nokia 5110 screen through SPI

All the tests conducted on my side are positive, including UART, SPI and I²C as per Standalone MSP430G2955.

@StefanSch Thank you very much for your help!

@robertinant Wouldn't be nice to add the MSP430G2955 to the main distribution?
