If you can describe what you need at the host and device ends perhaps other users can help you with the coding. Remember, you are the "Tonokips Reprap" expert. What is GCode? All we understand is the Maple. Some users are also Arduino experts.</p> <p>Besides the test code which you have shared what else have you tried and what works?</p> <p>For example, what characters are received/sent by the host system, what type of calculations are performed by the Maple board, and what type of other hardware (eg. motors, sensors, heaters, fans) are controlled by the Maple board?</p> <p>At a more basic level, why are you trying to switch to a different microcontroller board? Is there something the Maple can do which the Arduino will not accomplish?</p> <p>Here is a discussion of USB concepts: <a href="http://forums.leaflabs.com/topic.php?id=692" rel="nofollow">http://forums.leaflabs.com/topic.php?id=692</a></p> <p>Not everything I say in the USB discussion is correct, so be critical of what you read. However, the one important USB concept which you should focus on is the "data packet".</p> <p><a href="http://forums.leaflabs.com/profile.php?id=843">Stephen from NYC</a> (full disclosure: I am not a member of the LeafLabs staff) </p> http://forums.leaflabs.com/topic.php?id=724#post-4285 Tue, 12 Apr 2011 09:23:36 +0000 CidVilas 4285@http://forums.leaflabs.com/ <p>In the serial terminal in MapleIDE I type '1234567890' at a time and I type '*' to clear and create a new line.<br /> 1234567890123456789012345678901234567890<br /> the above line sent to the device will lock it up, while<br /> 123456789012345678901234567890<br /> Will not lock up and echo back after plenty of sends.</p> <p>I hope that makes sense.

I prefer the current naming convention, because the complete version number is visible (for all supported OS).</p> <p>I do not know which browser you use with Mac OS, but Firefox shows the name of the file in the lower left hand corner of the browser window when the cursors passes over a hyperlink. If you see a web page with two or three files with the same software "version", just use the mouseover trick to see which file applies to your system.</p> <p>A few observations:</p> <p>The February 13 snapshot has a bug in <code>SerialUSB.read()</code> which occurs if you are reading more than one character (which you are *not* doing in your sample code).</p> <p>If I am counting correctly <code>SerialUSB.print(&quot;\n Break \n&quot;);</code> sends 9 characters at a time and not ten. Are you counting <code>SerialUSB.print(character);</code> as the tenth character?</p> <p>As I mentioned above <code>SerialUSB.write(buffer, length)</code> seems to work reliably for me (using a Windows system) for sending large amounts of data.</p> <p>See the questions and code described in this topic (go to the second page):</p> <p><a href="http://forums.leaflabs.com/topic.php?id=639" rel="nofollow">http://forums.leaflabs.com/topic.php?id=639</a></p> <p>If all your characters are 8-bit characters you will not have to worry about bit-shifting (in the example, gbulmer's code was a solution to sending 12-bit values).</p> <p>I still have not had the time to test the low level USB API described above by poslathian.

The February 2011 IDE snapshots with the improved <code>Serial.USB</code> functions include:</p> <p>1) linux (32-bit); a tgz file<br /> 2) mac os (10.6); a dmg file<br /> 3) win (xp); a zip file</p> <p>I am not giving you the direct link to the compressed 32-bit Mac OS X file, because I want these instructions to be as useful to as many users as possible.</p> <p>I have not tried the low level USB API functions suggested by poslathian. (EDIT: I fixed the link above in poslathian's hyperlink so it does not include the closing parenthesis).</p> <p>However, the <code>SerialUSB.write(buffer, length)</code> function works well, especially when the length is 64 (the size of the USB buffer). The <code>SerialUSB.print(char)</code> function may not send the character until the "timeout" value is exceeded.</p> <p>For speedy USB transmissions one strategy is to divide your long string using a 64 byte buffer sending the entire buffer with a single <code>SerialUSB.write(buffer_buffer_64_char, 64)</code> command.</p> <p>Let us know how things work!</p> <p><a href="http://forums.leaflabs.com/profile.php?id=843">Stephen from NYC</a> (full disclosure: I am not a member of the LeafLabs staff)</p> <p>[my current <a href="http://forums.leaflabs.com/topic.php?id=690#post-3949">development system</a> (old, but still working)] </p> http://forums.leaflabs.com/topic.php?id=724#post-4254 Sat, 09 Apr 2011 03:13:10 +0000 CidVilas 4254@http://forums.leaflabs.com/ <p>I see that the latest snapshots are only for windows.

CidVilas, please do use the snapshot releases, as they come with improvements to the SerialUSB. We have been doing our best to improve it with each release, and the last snapshot had a rather major patch to serialusb installed. I also recommend, for when you are scuttling large amounts of data through the usb, you try and use the low level usb api (see <a href="https://github.com/leaflabs/libmaple/blob/master/libmaple/usb/usb.h">https://github.com/leaflabs/libmaple/blob/master/libmaple/usb/usb.h</a>) which requires a working knowledge of pointers but works much more quickly than SerialUSB and has the ability to actually send multiple bytes in a single packet. </p> <p>add "usb.h" to the top of your sketch and use:<br /> uint32 usbSendBytes(uint8* sendBuf,uint32 len);<br /> uint32 usbBytesAvailable(void);<br /> uint32 usbReceiveBytes(uint8* recvBuf, uint32 len);</p> <p>sendBytes will return the number of bytes sent, which may be less than the number you intended! (so check the return value and try again!). receiveBytes will return the number of bytes received, which may be less than the number of bytes you asked for (so again, check the return value and try again!). These functions are asynchronous, simple in implementation, and worth the extra complexity when working with large strings. </p> <p>If anyone finds bugs in the serialusb, please do post with as much detail as possible! The snapshots improvements will obviously be baked into the next major release </p> http://forums.leaflabs.com/topic.php?id=724#post-4222 Thu, 07 Apr 2011 16:58:32 +0000 CidVilas 4222@http://forums.leaflabs.com/ <p>Tonokips is just one of the many arduino firmware flavors available for reprap systems.
