#Wire library energia how to
My first example shows how to set the output frequency of the programmable oscillator LTC6904. But the same code can be used with any chips within the MSP430G2 family that supports the I2C functionality by simply changing the header file in the include statement. The code examples included here are built under TI’s Code Composer Studio V5.1 for MSP430G2231. Also you can refer to TI’s MSP430x2xx Family User’s Guide for more details. For more detailed background information on implementing I2C on MSP430G2 devices, you can check out this TI Wiki. In both examples, the MCU is configured as I2C master. The I2C code I am using is adapted from the I2C Explorer project on 43oh forum. The library code can be downloaded towards the end. In this post, I will show a couple of examples of using the MSP430 Launchpad as an I2C master to communicate with slave devices. This is because P1.6 is the SCL pin and the connected LED may cause the output voltage to stray from the desired logic voltage levels. Last week, I mentioned that in order for the I2C bus to function correctly when using the MSP430 Launchpad you might need to remove the jumper on P1.6.
