  1. Thank you roadrunner84. I was also thinking about UART. Do you know about any energia sample, implementing such a system? I found one such example here. But it's implemented in CCS, which I always found very complicated. Any energia example will be much appreciated!
  2. I am looking for a sample project developed in Energia which implements asynchronous serial communication between two MSP430G2553 boards. The overall system is supposed to work as a chatting system. Each board should work as a transceiver, i.e., both transmit and receive data. Each board will send letter/word using ASCII encoding. I can find few stuff similar to this, but not in energia platform. If there's no sample code available, I would like to know the answers to the following questions: 1) Which option should I use for such communication? UART or I2C? 2) What can be a decent baud rate for such communication? Please let me know if you have any question. Thank you in advance for the support.
  3. Hi, I am trying to connect two MSP430G2553 launchpads (in order to program/control) to a single computer. I thought it would be a simple task, but something is not going right. Do I have to run two instances of Energia (by running the program twice), or I can switch COM interfaces within the same instance. I guess someone must have tried it... please share your experience, or some pointer to online resources are welcome as well. I understand, my question sounds a bit vague, and confusing. Please let me know, if you require additional information to answer it. Thank you in advance.

    Driving 3V relays using MSP430G2553

    I really appreciate your help. I think I get the idea. I will let you know, if I face any other difficulties. Thank you.

    Driving 3V relays using MSP430G2553

    Sorry, my bad. I forgot to mention the relay model. It's a 3V relay from Omron, and the parts ID is: G5V-1. Thanks for your suggestion regarding transistors. I would really appreciate if you could provide me a pointer towards similar example, which shows detailed schematic.
  6. Hi, I am trying to operate a 3V relay (from OMRON) using MSP430G2553. The relay is a SPDT one, with 6 PINs. I am not quite sure how to wire a6 PIN relay (I have some experience with 5 PIN SPDT relay), and I cannot find much information in the internet. I was also told that, for driving a 3V relay, I would not require transistor + diode combination. For your information, the relay has a rated coil current of 50 mA. Can anyone help me on understanding the wiring structure of the relay? How to interface it with MSP430? Also, is it true that, I can operate the 3V relay without separate transistor + diode combination? I do not have much experience in microcontroller, particularly in MSP430 platform. Any suggestion is welcome. Thank you in advance for your support.
