Now I am searching some materials about DSP on Maple. The signal I will processing is around 20-30 MHz. Do you think I can do it on maple? I am not sure the sampling frequency of this board </p> http://forums.leaflabs.com/topic.php?id=2295#post-12070 Fri, 27 Jul 2012 16:37:31 +0000 mbolivar 12070@http://forums.leaflabs.com/ <p>Did you try Bionic-Badger's <a href="http://forums.leaflabs.com/topic.php?id=73#post-788">step-by-step Win7 instructions</a>?</p> <p>Are you able to use <a href="http://leaflabs.com/docs/troubleshooting.html#perpetual-bootloader-mode">perpetual bootloader mode</a>? </p> http://forums.leaflabs.com/topic.php?id=2295#post-12037 Thu, 26 Jul 2012 23:47:42 +0000 Anonymous 12037@http://forums.leaflabs.com/ <p>Sorry, this is my error information: I have tried the BUT_REST method which doesn't work:<br /> "<br /> Going to build using 'armcompiler' (ARM)<br /> Compiling core...<br /> No libraries to compile.<br /> Compiling the sketch...<br /> Linking...<br /> Computing sketch size...</p> <p>C:\Users\AppData\Local\Temp\build828608818893903445.tmp\Blink.cpp.bin :<br /> section size addr<br /> .data 12960 0<br /> Total 12960</p> <p>Binary sketch size is reported above.

I just got my Maple v5 recently and developed our project on this powerful board. In the past, we used Arduino UNO. But now we require more accurate output voltage, so we move here.<br /> Now I have one problem. I just tried to upload Example program "Blink" to the maple v5. IDE always says "Couldn't find the DFU device: [1EAF:0003] ". I know this is an old story. But could anyone tell me what I should do or give a CORRECT link?<br /> Thanks.<br /> By the way, I would like to talk about my project here to see if some one could give me some ideas.<br /> What I want to do is get 3 DC signal with accuracy at 1mV. My design is to use PWM with RC circuit. But I am afraid the RC circuit couldn't work so good. So, what should I do? Using Maple with DAC?<br /> Thanks everyone </p>
