  1. Old Cow Yellow indeed. Nice to see you again!
  2. I am an old hobbyist but totally new to C2000 etc. Interested in using C2000 Piccolo LaunchPad to emulate a certain ancient machine. --OCY
  3. It is better than the LaunchPad. But not 34 time better.
  4. Vcc, Vss, plus the two SBW pins (RST & TEST).
  5. I do not think buffers need to be initialized, to zero (0) or any particular value. When you fill a buffer, the previous value is replaced. It does not matter what the value was. If you do not fill a buffer and try to read it, the value is meaningless and does not matter what the value is.

    3-Pin MSP430?

    3-pin? No. But 4 pins is possible. Vcc, Vss, RST, and TEST are needed to program the Flash. After programming the Flash, you could cut RST and TEST too and get a 2-pin "functional" chip! The "function" is to sense Vcc and Temperature and transmit them to a near by radio. I did that without connecting anything to any Port Pins. But I have not tried actually cutting off those pins,
  7. Hello, I think you should consider a SCR or some kind of solid-state switch instead of a electromechanical relay. Do you have data for life expectancy of such a device if you make-and-break at the rate of once per second? -- OCY
  8. The button S2 might bounce. If it bounces an odd number of times, it appears to be "working". But if it bounces an even number of time, it appears to be "not working".
  9. Mark the calendar, but do not hold you breath. It is probably for G2xx3, with UART etc.
  10. Here is another example. http://e2e.ti.com/support/microcontroll ... 93751.aspx Posted by Doug Bennett replied on Wed, Feb 16 2011 10:33 PM
  11. RobG, Thanks. Are you using CCS? Which version? Good to know that it works for you/ --OCY
  12. On the TI E2E, there were a quite a number of posts that say they cannot use CCS to program G2453 at all. What were you using? And how is it now? I suspect that some of TI's assembly site are not up to par. What are the markings on the chip you got? Especially the string of characters after the TI logo? I am very curious about this. Thanks --OCY
  13. How are the dip switches connected? Each between a P1 pin and ground? Are there pull-up resistors? If not, you could use the on-chip P1REN and P1OUT to pull them up. Depend on pull-up, R, and the parasitic capacitance, C, you may also need to delay ~2*R*C after power up before you read the input.
  14. F5xx and F6xx have hardware FLL. That is, the DCO can be dynamically adjusted by hardware according to a "reference". You normally do not need to calibrate the DCO. If you do want to, you need to disable the hardware DCO and do it your way. Read the User's Guide for F5xx/F6xx, not the one for F2xx/G2xx.

    fatal error

    But before you added one, there may already exit one.
