Now it's saying that it's not getting a response from the STM32. To use the FTDI chip on an Arduino as a USB-to-Serial converter to use with stm32loader.py, you'll need to make sure that the Arduino's processor is programmed so that it doesn't interfere with the communication. You could also either remove the Arduino's processor and use the FTDI chip alone (probably the easiest route) or write a sketch for the Arduino that makes it transparent.</p> <p>I noticed that you said you were using the Audio Codec Shield. The example sketches for that shield disable Maple's virtual serial port (with the line "SerialUSB.end();" because the way the USB interrupts are serviced creates timing difficulties. </p> http://forums.leaflabs.com/topic.php?id=882#post-16153 Mon, 24 Sep 2012 14:51:54 +0000 scott 16153@http://forums.leaflabs.com/ <p>Update: Tested it on a friend's Macbook.

I'm taking a gander at the instructions, but I'm not clear on how to physically wire it up using an Arduino (I don't have an FTDI breakout board):</p> <p><code>If you do use an FTDI breakout board, first make sure your Maple is disconnected from an external power source, be it battery, USB, or barrel jack. Then, connect the FTDI board’s TX pin to Serial1‘s RX pin (labeled “RX1” on the silkscreen), FTDI RX to Serial1 TX (labeled “TX1”), FTDI ground to ground (labeled GND), and its 3.3V pin to Vin. On Maple Mini, you will also need to tie BOOT1 (pin 2) to ground.</code></p> <p>Does this mean the Arduino's TX pin to Maple's (Serial1) RX pin? etc?</p> <p>UPDATE: So yeah - I guess that's what my question above meant. I'm trying to go through an Arduino Uno: do I need to upload some sort of special sketch to it first?

One for DFU and one for serial. In both cases the device has to be present, which means you have to get the device into dfu mode to finish installing the drivers and you have to have it in the cdc-acm mode (or you have to load valid code in that mode) to get the other driver installed. </p> <p>I tried to teach a class on using c with the maple and we spent the majority of it getting windows to cooperate.<br /> Its just ugly, and with the $igned driver$ policies being added to 8 its going to get worse. </p> http://forums.leaflabs.com/topic.php?id=882#post-15522 Fri, 21 Sep 2012 13:24:35 +0000 scott 15522@http://forums.leaflabs.com/ <p>I just ran into what appears to be the same exact issue, while playing around with a the audio codec shield (I'm on Windows 7).

The directions leave out the second step(took me a few days messing with it to figure out that was my problem).</p> <p>Go through the same steps (Control Panel&gt;System&gt;Hardware Tab&gt;Device Manager. For me, it showed a yellow question mark next to Maple 3, above the Ports(COM &amp; LPT). click on it, driver tab, update driver, and when the wizard asks for you to search for drivers, direct it to MapleIDE\drivers\mapleDrv\serial (my ide is in MapleIDE, change it for your own directory structure).</p> <p>If I understood your problem correctly, that should fix it, it worked for me :)</p> <p>Cheers </p>
