  1. Thanks, Rei Vilo. I will try out your code and revert. 5528 vs 5529 - No, I haven't tried on the Launchpad. But, considering that the two cores are identical (and the pins are re-arranged appropriately), I do not expect major differences. MPL3115A2 data sheet is very 'generic' and brief in its I2C description. I couldn't use it to understand expected behavior for this specific case. - Misra
  2. @NurseBob - I have confirmed both SCLs (MSP430 and ESP) are at a nominal 100 KHz. And both instances have the pullups in position. @bluehash - Yes, pullups are in place. @Rei Vilo - You are right. For Energia, no argument is required for Wire.begin() as a master. However, for ESP8266(Arduino), before using I2C, pins for SDA and SCL need to be set by calling Wire.begin(int sda, int scl), if different from defaults. The code I pasted was the ESP version. Please see the comments on this line. Thanks for your time. I am specifically intrigued by the different res
  3. Hi Zeke, Would you have any LED rings left? I would like to buy two populated ones (without clock) or maybe three if priced reasonably ;-) Thanks - Inscribe
  4. Dear 43Oh, First post in 43Oh. Please point out mistakes. I am creating sample applications for a MSP430F5538 board in Energia environment. pins_energia.h has been suitably modified and board integrated into Energia (Version 18 at this time). Sample code to get I2C working (on MPL3115A2 Pressure sensor) has been tested on the ESP12 using Arduino environment . The same code fails in Energia. Code uses only wire.h (i.e., no device specific libraries included). The code is posted below: #include <Wire.h> // for IIC communication #define WHO_AM_I 0x0C #define MPL3115A2_ADDRE
  5. Hi 430oh, I am Misra from Bangalore. I run a small embedded development company, Inscribe Technovations. Currently, we are busy giving finishing touches to a MSP43x based eco-system (MISPINO), centered around Energia. Do wait for our launch announcement by 01April2017. - Misra @Inscribe
