(Question) SPI and I2C at same time
klerone posted a topic in Energia - MSPHi everyone. I'm new to this forum and new to TI mcu. Planing to get a launchpad with msp430g2553 I have experience with atmegas, and arduino ide. I have a project to have some sensors around with batteries and a central receiver to publish to internet, the will comunicate vía nrf24l01 which is a SPI device and in the array of sensors some of them are I2C. As I see the description I2C and SPI share the pin in Msp430G2, so my question: is possible to use both in the same project in a reliable way? I did this project with atmega328 and arduino ide but I read the msp4
[Energia Library] Bosch BMP085 Template Library
chicken posted a topic in MSP Energia LibrariesI finished up my first Energia project, a template library for the Bosch BMP085 temperature and pressure sensor. It uses I2C and supports temperature in Celsius and pressure in Pascal. https://github.com/astuder/BMP085-template-library-Energia I connected the GY-80 breakout commonly found on eBay, but it should also work with most other BMP085 breakouts, like the ones from Adafruit or Sparkfun. Note that I had to patch Energia to make 1-byte read work on MSP430G2553 with Rev1.5 LaunchPad. I also had to remove the LED2 jumper, probably due to too weak I2C pull-up. Update: Tested on La
