These should certainly have a different set of apis and the public libmaple API should developed with non cdc usb classes in mind.</p> <p>As for the cdc-acm changes: Nice!

Last I looked at the usb section its starting to get parsed into things that could turn into multiple classes if I ever get un-busy I plan to take a crack at midi. The meat of it is here:<br /> <a href="https://github.com/leaflabs/libmaple/blob/master/libmaple/usb/stm32f1/usb_cdcacm.c" rel="nofollow">https://github.com/leaflabs/libmaple/blob/master/libmaple/usb/stm32f1/usb_cdcacm.c</a>, HID will complicate things a bit because much more is done with the descriptors (usage pages). You could probably also just do the bulk transfers yourself. </p> http://forums.leaflabs.com/topic.php?id=2283#post-12086 Sat, 28 Jul 2012 06:17:44 +0000 asterix 12086@http://forums.leaflabs.com/ <p>change the baud rate on your computer. on windows you do this through device manager </p> http://forums.leaflabs.com/topic.php?id=2283#post-12001 Wed, 25 Jul 2012 15:39:34 +0000 Anonymous 12001@http://forums.leaflabs.com/ <p>Hello,</p> <p> I want to send data by USB in full speed or HID. I used SerialUSB but is very low to send data. Does anyone here can help with real USB in mini maple? Does anyone already used USB without emulate?</p> <p> Best regards </p>
