  1. Hi All, I cleaned up the site last week. This year has not been the greatest for me(and for alot). Pardon the neglect. True that the blog has not been update, but I have not seen much content on the MSP430/432. Also TI's E2E has been vastly popular. There was no "commercial" side. I still pay for server and forum licenses out of pocket. I've kept it up since there is alot of useful info and people benefit from it.

  2. Hi to all, are you interested in assembler language programming? if so, this could be of interest to you. the basic idea is a 5kB kernel embedded on a MSP430FRxxxx, capable of downloading source files, interpreting and compiling them. Associated with a minimalist IDE: a text editor, a generic preprocessor and a terminal to communicate with the embedded kernel. What is the craziest wish of a microcontroller programmer? In my opinion, it would be that once his source is modified, he clicks on the "build" shortcut of the editor and in a second, the program is compiled on the targ

  3. I decided "for the hell of it" to print out the MSP430 chip family User's Guide, all 676 pages of it (slau445). Total cost was ~$70 altogether including the $10 binder from Staples. I used bestvaluecopy.com for the printing - printed in B&W, with a thicker color cover sheet, 3-hole drilled, shrink-wrapped, and put it in my own binder. Reading the more esoteric parts of the book - like the PMM, SVS and CS systems - is actually much nicer in print I found. Just more comfortable to sit down at the table and *look* at the diagrams and text and hold my left hand under the page with the

  4. And with J7 removed, everything works just fine. Note to the future: if trying to do I2C on EXP430G2ET, remove J7. It probably says that somewhere in the user guide.

  5. I locked myself out by incorrectly programming GPIO reg C. I used the LMflashprogrammer to unlock it.

  6. As far as I can remember, the G2553 has a very small serial buffer. Just try to reduce the number of byte to send, e.g. AT: Instead of Enter AT commands:

  7. G2553 has a Hardware Serial Interface, so do not use the Software implementation. Serial BTSerial..... Should work

  8. Which MSP430 are you using? I recently tested it on an MSP430F5529 and that worked. One thing to note though is that pins 3 and 4 are already used by Hardware Serial which you use in your Sketch (Serial.xyz()). Try changing to different pins. I would suggest you try pins 11 and 12 if you are not using those for anything else. Robert

    Volt/Amp/Watt meter

    This is a simple voltage and current meter that uses the TI INA219 chip. Voltage measurement range is 0 to 26 volts with 4 mV resolution and current measurement range is -4 to +4 amps with 1 mV resolution (when using a 0.01 ohm shunt). The specs are inferior to a pair of quality multimeters, but it is a fraction of the price and shows wattage in addition to voltage and current. The Nokia 5110 display is used so the firmware could be enhanced to do simple graphing. Sending the measurements to a computer could also be done. Using the INA219 makes for a very simple circuit. The normal d

  10. The only problem, MAX7221 is a 5V device. You should be using MAX6951 for 3V applications.
