    MSP430AFE2xx related stuff
  1. Wow that is some great info. I really appreciate that. I love the idea of polymer clay too! But to just get started, I'm going to check out this adapter for now. http://www.proto-advantage.com/store/pr ... OgodkAkAZQ One other question. If I want to use an LCD display, what is a good one to play with that can display something like "888.88 W" and a backlight ability? Does it have to have a controller or whatever it is called built into it?
  2. thank you mbeals and cde! I am going to order a launchpad kit just so I can have it and become familiar. Most of the examples and help here is based around it, and in the end, I want to be able to take the programmed chip (MCU) and use it standalone so the dev kit shoudn't matter. The reason I was drawn toward the afe series was I had wanted to build a cheap energy monitor for inside of an outlet. I want to have some type of wireless communication for switching on and off and a tiny LCD screen to display usage. while googling, I came across the TI Smart Energy Meter, which in the diagrams has the AFE chip. It says it's built specifically for these type of applications, so it made sense to me. One thing I still get hung up on is the size of the chip. I like the size since I want it to fit in an outlet, butdo they make breadboards that fit a chip that small! I keep hear I/C Sockets, but I don't want to have to buy a 50 dollar socket just to use the chip. and it's bulky too. haha Anyway, thank you again!
  3. Hello everyone, Ok, I've taken my first baby steps into programming the MSP430 I have an it seems to have been successful. Thank you all for the assistance you have given, and the great links and books that I am still chewing my way through. Specifically the MSP430 Programming Basics one. To give a little background on my setup, I have an MSP430AFE253 sitting in a MSP-TS430PW24, the P1.0 LED blinking merrily, with the MSP-FET430UIF plugged into the JTAG and Code Composer Studio v5 on my Windows 7 computer. Phew! Is anyone else using this equipment? lol Oh and yes, I know the PW24 was way overkill and I should have bought the Launchpad... If anyone wants to explain to me what I would need in order to take this tiny MSP430AFE253 and put it into a launchpad and program it, I'm all ears! Anyway... now I'd like to take my learning a little further with the blinky example. I have an LED, but to my amazement, it's not as easy as just plug the LED into pin holes 11 and 12 and the LED blinks instead of the one on board. Here is the code I played with and modified a bit. Anyone have insight? I really wish there was some MSP430 videos explaining plug this here, that there, load this sample code and viola! I'm a trial and error type of personality, so if I can get it to work, I am usually pretty good at tweaking and adding/modifying things to see how it is affected. Thanks :? -Mike The code #include int main(void) { WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer P1DIR |= 0x01; // Set P1.0 to output direction for(; { volatile unsigned int i; // volatile to prevent optimization i = 50000; // SW Delay do i--; while(i != 0); P1OUT ^= 0x01; // Toggle P1.0 using exclusive-OR i = 20000; // SW Delay do i--; while(i != 0); P1OUT ^= 0x01; // Toggle P1.0 using exclusive-OR i = 75000; // SW Delay do i--; while(i != 0); P1OUT ^= 0x01; // Toggle P1.0 using exclusive-OR i = 70000; // SW Delay do i--; while(i != 0); P1OUT ^= 0x01; // Toggle P1.0 using exclusive-OR } }
  4. Welcome to the 4-3-Oooooh! Hope you find it as useful as I am!
  5. Greetings Phoenix! You are further than I am. Good luck with your projects. which MSP430 are you using?
  6. Greetings to you Curtis! What electronics experience do you have? What equipment are you using?
  7. Oh No! I should have known I could have done the programming with the launchpad. I tried to read everything I could, and I just didn't seem to find that definitive guide that said it could be done so I was suckered into the expensive route. Anyway, obviously alot more reading to do! Thank you for the warm welcome and gentle nudge in the right direction. Maybe I can send it back and get the launchpad instead. lol
  8. Hi Everyone, My name is Mike and I'm new to Microcontrollers. A few months ago I was talking to a coworker that is enrolled at a local college for electronics about circuits and bread boards and stuff. Almost immediately, ideas started popping in my head and I couldn't wait to get started with programming some myself. I initially was looking at the Arduino and PICAXE brands, but eventually came across the TI Smart meter documentation and thought how cool would that be to build something similar. So I decided to take the plunge and I bought the MSP-TS430PW24 and associated MSP-FET430UIF. The dev kit also came with 2 MSP430AFE253 MCUs. So this is where I am now! Ready to dive in. Before I have even put the MCU into the dev board, or plugged anything into my computer, I can see the first question has already presented itself. This chip is so darn tiny, I can see I have to find some type of interface to use it on a breadboard, or trainer. The fun begins! If any of you have worked with this chip or kits, feel free to let me know. I'd love the insight that can be provided. Otherwise, I think my first project, after making a light blink, is to start trying to build an energy meter for one lamp. Then perhaps trying to replicate a GFCI using the same MCU. and then after that, seeing about sending that data over wireless or powerline to another unit. Baby steps though. baby steps. Talk to you all soon I'm sure -Mike
