  1. yep i have. The picture below shows the mps430 wiring and code. the exact same thing works with the Arduino's I have also in the picture. ye
  2. Thanks for the reply Rei Vilo, For the MPS430FR4133 the Energia pin layout example lists the A4 and A5 pins as P1.4 and P1. I have attached the pins from the 2 boards together and complied the slave_sender code on 1 device and master_reader on the other. I have also tried attaching a 3.2k resistor to each of the pins to VCC as it said to do this on another forum post regarding I2c. Any recommendations would be appreciated. I did read some of the I2C forum posts in this area and have not found a solution. I don't think i posted the same question twice?
  3. Hello again, I am trying to connect up 2 MSP430FR4133 using the slave_sender and Master_reader examples in the energia given examples. There is no information about which pins to use but RXD and TXD are the only pins outputting on the scope so i have tried these pins. I have also tried connecting up the pins that say they are for SPI on the pin layout to no success. Any help would be greatly appreciated. Kind regards, Chris
  4. Thanks guys, Very helpful.
  5. Hey everyone, I am trying to reduce the power consumption of my msp430FR4133 by reducing the clock speed from 8MHZ. I am using the http://annem.github.io/ADXL362/ example code as a base which sets the default clock speed to 8MHZ. I have read that the Wiring.c file defines the clock speed but I cannot find where F_CPU is defined. Any help would be greatly appreciated thanks.
