  1. Thanks spirilis once again. I confirmed your frequency number of 100 Khz on the scope to be correct. Did you infer it from the energia libraries ? Also I put the external resistors and my problem is resolved. Two followup questions: The MSP430G2553 spec says that there are internal pullup/pull down resistors available on Port 1. Does any one know their value ? Can these resistors be enabled using CCS if not energia. Thanks in advance,
  2. Thanks spirilis. I am just using the energia Wire library and not playing with frequency at all. What is the default clock frequency ?
  3. First post!!!! I want to enable internal pull-ups for i2c on pins P1_6 and P1_7. A search on existing discussion on this topic yielded this: http://forum.43oh.com/topic/2641-i2c-lcd/ "I2C requires a pull up resistor on both SCL and SDA. You can enable the internal pull up in the msp430 on the I2C lines by doing: pinMode(P1_6, INPUT_PULLUP); pinMode(P1_7, INPUT_PULLUP);" Is that right? I tried it and it does not work. I was wondering that i2c SDA is bidirectional so setting pinmode as INPUT might not be the right thing. Has anyone tested this and gotten it to work without external p
