Re: [PIC] Problems Programming the 10F222 with PICSTART Plus andAC163020

In MPLAB drop down the "Configure" menu, select "configuration bits" and make sure the check box "configuration bits set in code" is checked. If this is not checked, the configuration defaults to what is set in this configuration window. I have encountered similar problems with watchdog timer due to not having this box checked.

I see a chicken-and-egg problem - If your nose is blocked to begin with, how do you exhale fully through your nose? Cheerful regards, Bob Tomás Ó hÉilidhe wrote:

Note that the linked MSFT GPS unit is likely not one of the new generation receivers. You really want to get one like the SiRF III or equivalent. They're much more sensitive, faster to acquire lock, lower power consumption, etc. -Pete On Aug 28, 2008, at 6:22 PM, M. Adam Davis wrote:

[OT] Evidence for Correlations Between Nuclear Decay Rates andEarth-Sun Distance

Chris Smolinski — 2008-08-29T15:03:10

Evidence for Correlations Between Nuclear Decay Rates and Earth-Sun Distance Unexplained periodic fluctuations in the decay rates of 32 Si and 226 Ra have been reported by groups at Brookhaven National Laboratory ( 32 Si), and at the Physikalisch-Technische- Bundesandstalt in Germany( 226 Ra). We show from an analysis of the raw data in these experiments that the observed fluctuations are strongly correlated in time, not only with each other, but also with the distance between the Earth and the Sun. Some implications of these results are also discussed, including the suggestion that discrepancies in published half-life determinations for these and other nuclides may be attributable in part to differences in solar activity during the course of the various experiments, or to seasonal variations in fundamental constants. http://arxiv.org/pdf/0808.3283v1

Re: [PIC] Function scope in MPLAB C

Harold Hallikainen — 2008-08-29T15:00:25

As you and others have pointed out, the key is to make the function static. I've always thought the dual use of the word static was strange. It makes most sense to me in declaring a local variable. There, the word static is the opposite of the word dynamic. The memory is statically (permanently) allocated as opposed to being allocated just within the function, the deallocated. The other use of the word static (outside a function) speaks to the scope of the variable (or function) instead of how the memory is allocated. Static here means the variable or function is visible only in this source file. I can't really think of why the word "static" was used here. In the memory allocation case, it makes sense, as static is unchanging. The allocation does not change. But how do we make sense of the word static with regard to scope? Or was this just a way of saving a little space in the parsing mechanism of the compiler (fewer key words to deal with - the meaning depends upon the location)? Harold

[EE] Lattice FPGA JTAG question

Sean Breheny — 2008-08-29T14:53:59

Hi all, I've posted the following question to the forums at latticesemi.com with no answer so far. I was wondering if anyone here might know the answer. Can someone please tell me what the minimum set of JTAG pins is for ispTracy use on the LFXP3? I am designing a board using the LFXP3 and in the past I have left the INIT,ISPEN, and TRST/DONE pins from the ispDownload (USB) cable unconnected to the board. I seem to remember reading that one of these is needed for ispTracy use, but I cannot find that reference anymore. Ideally it would be great if someone could point me to a schematic of exactly how I should hook up the ispDownload to the LFXP3's JTAG pins for both programming and ispTracy. Thanks, Sean PS For anyone who doesn't know, ispTracy is an "IP core" for a logic analyzer that you can link into your FPGA designs.

FWIW, some companies at SMTA (like Essemtec IIRC) were touting machines with feeders that would allow you to use small strips of tape with just a dozen or so parts. And those weren't just the $200k+ machines. Cheers, -Neil. John Day-5 wrote:

VIM is everywhere. Platform independent, and the most comprehensive + free. Not for everyone though as have to learn it to use all the advantages it has, but the initial learning curve does not take that long as it seems to be, and then the only danger is that you wont even be able to breath without that.

Is it because the device is connected to the programmer (and once the CP was on accidentally) ? Or the CP is on in the HEX file? Did you try to clear the CP with bulk erase? Tamas On Fri, Aug 29, 2008 at 2:26 AM, Tim Parnaby dti.com.au> wrote:

What I find really annoying is that you can't tell from the site if you're going to get a single length of tape or multiple packs - when I last queried this they said that for qtys >100 they supply as single tape, but in the past I've had multiple packs above these qtys. Yes - seems a bit random which parts are available re-reeled - I can understand it for parts with unusual tape sizes but it's not just those that aren't available. Pity their search sucks though - '10K 0805' and '10uf 1206' returned no results..! This is one area where Digikey works well, except that they don't know what 'nf' means. Farnell now do free re-reeling - don't know if their US arm Newark also does it.

I tried this long ago. http://forum.microchip.com/tm.aspx?m=112347 In the end, I think you can use this methods if you are not using the hardware components of MPLAB. If you plan to use the hardware components of MPLAB, using Virtual Machine is the way to go. Or IMHO use dual boot and Windows XP is a better option. Xiaofan
