When I tried one of the SPI examples ( the last one on the SPI hardware page) I noticed that it doesn't work as expected.</p> <pre><code>// Use SPI port number 1 HardwareSPI spi(1); void setup() { // Turn on the SPI port spi.begin(SPI_4_5MHZ, MSBFIRST, 0); pinMode(9,OUTPUT); // this line is always here pinMode(10,OUTPUT); // this line is always here } void loop() { digitalWrite(9,LOW); // this line was added later digitalWrite(10,LOW); // this line was added for 1 run spi.write(random(255)); digitalWrite(10,HIGH); // this line was added for 1 run digitalWrite(9,HIGH); // this line was added later }</code></pre> <p>there is a screen dump at the following link to illustrate the results <a href="https://drive.google.com/file/d/0B1ghmDU_EL2BME1Pd28yb0p1d1E/edit?usp=sharing" rel="nofollow">https://drive.google.com/file/d/0B1ghmDU_EL2BME1Pd28yb0p1d1E/edit?usp=sharing</a><br /> Running the 2 variations of the program with my logic analyser gives these 2 results. Notice how the CLK((7) and MOSI (6) don't line up with the SS(5) as you would expect or my indicator (4 pin9) and when I remove the SS toggle it doesn't get activated by the SPI library but the CLK and MOSI still fire. So what am I doing wrong or are there problems with the library?<br /> Cheers<br /> Mike </p> http://forums.leaflabs.com/topic.php?id=74079#post-104828 Mon, 28 Oct 2013 16:05:40 +0000 ftb44 104828@http://forums.leaflabs.com/ <p>Hi everyone,</p> <p>I am about to use the Maple in a project with a little bit of DSP, and I am worried about the fact that I can only sample once per analogRead(). To me this suggests that my sample rate might not be constant! Has anyone written anything that could work around this non-determinism? I know that the Maple is capable of incredibly fast analog reads, and I have a few ideas on how to stabilize the time between samples--but I feel like there must be better coders out there who have already solved this problem. </p> http://forums.leaflabs.com/topic.php?id=1030#post-6285 Sat, 10 Sep 2011 08:57:59 +0000 Shay 6285@http://forums.leaflabs.com/ <p>Hi, In my search for a good cortex M3 dev platform i found your site a very long time, but when i saw a plan for a mixture of arm cortex m3 with an fpga option awaiting in your to do list, i have decided to wait for it.<br /> since then a very long time has gone and I'm still waiting for it.<br /> last night i stumbled upon this fpga/cpld open source dev board which can be programed using an on-board USB plug and free software.<br /> I think this can be a very good starting point for a mixed ARM CORTEX M3 and FPGA/CPLD mixed board, so here is the link: <a href="http://xess.com/prods/prod048.php" rel="nofollow">http://xess.com/prods/prod048.php</a><br /> I hope to see some sort of a maple with fpga soon. </p> http://forums.leaflabs.com/topic.php?id=10455#post-24005 Sun, 31 Mar 2013 20:30:41 +0000 bnewbold 24005@http://forums.leaflabs.com/ <p>Hi everybody!</p> <p>You may have noticed that most distributors of the Maple and Maple Mini are out of stock right now. This is our fault, we thought that we had placed a large order for new boards months ago, but production didn't actually start until a few weeks back. We will try to get the next batch of boards tested and out to our distributors as soon as possible; in the meanwhile, we have a few extra boards around the office and can sell them on a one-off basis if you have a dire need.</p> <p>Sorry for the delay and goof up on our end, especially following our recent blog announcement that production would continue. We will continue to distribute the Maple and Maple Mini devices for the foreseeable future. </p> http://forums.leaflabs.com/topic.php?id=10619#post-24497 Sat, 13 Apr 2013 13:00:05 +0000 bnewbold 24497@http://forums.leaflabs.com/ <p>This caught my eye: <a href="http://www" rel="nofollow">http://www</a>. discourse.org</p> <p>Concerns:<br /> - would need custom import code to transfer from bbPress<br /> - JS UI might not fallback well for simple/accessible user agents (lynx, wget, etc)<br /> - might need custom code for redirects (vs. a static file dump of existing posts)<br /> - we probably have more pressing concerns than upgrading forum software (eg, accepting libmaple/IDE bug patches) </p> http://forums.leaflabs.com/topic.php?id=10452#post-23995 Fri, 29 Mar 2013 18:07:09 +0000 Sh33p 23995@http://forums.leaflabs.com/ <p>Any one got one for sale or can the leaf labs team charge me for one directly?

We'll give a more comprehensive and long-term update later, but for now I was wondering what the most frustrating problems people are running in to with the existing Maple toolchain and documentation. Many of the bugs in our tracker are (shamefully) months or years old; which ones are still causing difficulties?</p> <p>Things that are less likely to happen any time soon are: fully tested support on the latest Microsoft Windows platforms and world-changing improvements in cross-platform SerialUSB/DFU USB interop, because (as always) improvements there are dependent on OS vendor decisions and could break backwards compatibility.</p> <p>Things that are more likely to happen soon are: integrating outstanding pull requests to libmaple, Linux platform support and packaging, updates to the libmaple toolchain (gcc-arm-embedded 4.7, etc), adding peripheral support to libmaple, and API-preserving bug fixes. </p> http://forums.leaflabs.com/topic.php?id=10198#post-22239 Mon, 04 Feb 2013 01:36:24 +0000 kyoji 22239@http://forums.leaflabs.com/ <p>Greetings</p> <p>I was experimenting with MAIPLE mini.<br /> I wrote to the DEVICE Maipleminibootloader of STM32F103CB,<br /> That is USB DEVICE<br /> DVICE is recognized as unknown as "6 &amp; 176E48BB &amp; 0 &amp; 1 USB \ VID_0000 &amp;<br /> PID_0000 \".<br /> I use the DEVICE of STM32F103C8<br /> Be properly recognized "USB \ VID_1EAF &amp; PID_0003 \ LLM_003".<br /> Omit the cutoff 3.3vpullup to deal with USB-HISPEED, I have to remain connected.<br /> Although the same to another substrate using a STM32F103C8,<br /> I recognize correctly.<br /> I will be recognized if you care what the point?</p> <p>Best regards </p> http://forums.leaflabs.com/topic.php?id=10060#post-21925 Tue, 08 Jan 2013 15:10:03 +0000 cmartin 21925@http://forums.leaflabs.com/ <p>How can one change their password?

Right now, here's my top three; feel free to add your own:</p> <p>- Bootloader/auto-reset isn't reliable enough, especially on Windows<br /> - SerialUSB isn't reliable enough<br /> - IDE source code parsing/compiler error checking isn't reliable enough</p> <p>edit: added a third item </p>
