keyboard - USB HID Atmega 32u4 Arduino - system device ID / name changing from default Arduino leonardo -

-

i'm building usb hid device using arduino leonardo mini clone, based on atmega32u4. particular ic has got usb controller build in, , turning in hid device simple, need include keyboard.h , use keyboard.print...

the question , can set/define name of device shown, when arduino connected pc, because @ moment named arduino leonardo.

the default automated name tty usbmodemhidp1

in system preferences can see:

  id product:   0x8036   id vendor:    0x2341   wersion:  1.00   serial number:    hidpc   speed:    12 mb/sek.   vendor:   arduino llc   id location:  0x14200000 / 16

so in arduino keyboard.h can change name, or id's ? possible ? because in opinion should can't find right place, , not have experience wit arduino avr working microchips mplab x before different ic's ;).

any appreciated best regards

the "iproduct" string sent board on enumeration tells operating system gives human-readable name. value of string set near top of usbcore.cpp in hardware/arduino/cores/arduino/. it's unicode string need looking 'l', 'e', 'o', 'n' [...] not "leonardo". string used depends on pid number of device (also sent during enumeration) given in boards.txt.

for distributing own custom hardware based on leonardo there need provide own vid.

also there can used alternative firmware. arduino '32u4 bootloader, caterina, can found under hardware/arduino/bootloaders/caterina. requires lufa in order build.

hope others in solving same problems :) cheers, topic closed

i've tried installing (and re-installing) android studio several times now, , each time, studio isn't able create new android project. when attempt initial android studio window (ie. basic 'create', 'open', 'import' etc options), i'm asked of questions in wizard, brief progress dialog, followed nothing @ all. if open incomplete project process creates choosing 'open' list, can try choosing create new android project menu. this has same issue, error message in output console time... java.lang.noclassdeffounderror: com/sun/xml/internal/bind/v2/model/annotation/annotationreader (wrong name: com/sun/xml/internal/bind/v0/model/qnnotation/annotationreader) note: when installed android studio, installed incompatible jdk (1.8, not 1.7). have had go default project settings change jdk uses 1.8. does know how can avoid this? there place should downloading jxb classes? missing in java paths? this appears have been caused cor

Decoding a Python 2 `tempfile` with python-future -

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
