MSP430FR5994 Launchpad and I2C Module 2


Recommended Posts

Hello for information.

I work in this moment for data logger. I need 2 SPI port (LCD and SD) and 1 I2C port (sensors). I Use TI MSP430FR5994 Launchpad.

With Energia E18, impossible to use SCL (2), SDA (2), pin 9 and 10. (I need Pin 14,15 for I2C/SPI LCD, and I need Pin 48, 50 already connected on SD connector in launchpad), 

 

1) don't forget to setup I2C module number:       Wire.setModule(2);          

 

2) modify Pins_Energia.h as describe bellow   in  \Local\Energia15\packages\energia\hardware\msp430\1.0.3\variants\MSP-EXP430FR5994LP

 (see link in Energia Preference menu).    Select ' PORT_SELECTION0'
