Dotaz: Arduino Mikro, Raspbian/Debian, nejede ttyACM.

[Bill Gates]

Ahoj, koupil jsem arduino mikro pro jednu svou mikro aplikaci, protoze mam zkusenosti s arduinem a tato verze se mi moc libi. Po pripojeni do USB u me na notebooku (Debian 7) jsem mel problem

[1081271.069436] usb 3-1: new low-speed USB device number 34 using ohci-pci
[1081271.213354] usb 3-1: device descriptor read/64, error -62

[1081273.284995] usb 3-1: device not accepting address 37, error -62

Samozrejme googlil jsem tuhle chybu co se dalo ale nenasel nic funkcniho.

Mam tu krome notebooku i raspberry. Tak jsem nevahal a zkusil. Preci jen je tam Raspbian, kdo vi co bude jinak ... Vysledek:

[1526291.000921] usb 1-1.4: new low-speed USB device number 4 using dwc_otg

[1526291.106107] usb 1-1.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0

Bezva.. Jsme o krok dal, ale problem je v tom, ze abych si s tim mohl pohrat pres Arduino IDE, potrebuju /dev/ttyACMX ...

Treba tahle:

[root@s8.pi]# ls -l /dev | grep ACM
crw-rw---T 1 root dialout 166,   0 Nov 14 15:22 ttyACM0

Jak to udelat u toho attiny85 aby se to taky chytlo jako ttyACMX ?

Diky za jakoukoliv napovedu. Jdu si dal lamat hlavu, kdyz na neco prijdu dam kdyztak vedet, pokud nekdo vi, budu vdecen ... :)

PS: Arduino Mega ma idVendor=2341, idProduct=0010. Nebude problem v idVendor=16d0, idProduct=0753 pro to mikro arduino? Ze system nevi ze to ma taky brat jako ACMtty? Ovsem jak to udelat ?

Ale to je až druhý krok, konfigurace avr-gcc a avrdude pro tu desku. Vytvoření sériáku s tím nesouvisí.

Ta AtTiny používá softwarovou implementaci USB a vypadá to, že si s ní tvůj systém nějak nerozumí.

[Jendа]

Když na tom RPi zkusíš ručně zavést cdc-acm modul, případně připojíš to malé Arduino až po připojení té Megy, tak ho to detekuje?

[Bill Gates]

Pripojena je mega, uno a ted opet i mikro.

s cdc-acm netusim jak se presne pracuje ... a jak tomu rict ktere zarizeni ma na to pouzivat. Nicmene jak jsem odkazoval vyse, vsimam si ze oni v tom "kroku 2" maji vysedly serial port ve screenshotech arduino IDE. Tak otazka jestli to nekomunikuje nejak jinak nez pres ttyACM ... jen takova uvaha ..

[NN]

Vyzkousej jiny nez USB3 port.

[Bill Gates]

jiny port (neUSB3) totez...

Takze na ntb uz taky jsem o krok dal ... jen teda tedka ACMTTY nebo nejak jinak to rozchodit.

[NN]

Mohlo by pomoc pridat do udev 49-micronucleus.rules reloadnout udev a pripojit.

[kulichs]

Příloha:

• 49-micronucleus.rules (1310 bytů)

Já jsem si musel upravit 49-micronucleus.rules takto snad ti to pomůže

[crown]

https://github.com/micronucleus/micronucleus/wiki/Ubuntu-Linux

Me se teda arduino micro pripojilo rovnou. Muzes mit ale trosku jinou verzi s jinym ID.

[Bill Gates]

Po pridani 49-micronucleus.rules ktery u me na NTB nebyl, je stav stejny. ttyACM se nevyvori. Nechce to reboot NTB? Ted sice nemuzu ale pokud ano jak bude prilezitost zkusil bych.

Po provedeni

udevadm control --reload-rules

stale stejny stav.

[NN]

Rekl bych, ze by to chtelo vymenit xhci_hcd za ehci_hcd, pripadne manualne zavest cdc-acm. Otestuj:

rmmod xhci-hcd
modprobe ehci-hcd
modprobe cdc-acm

a pak to znovu zapoj..

[kulichs]

A skoušel jsi v Arduino IDE spustit nahravaní vytáhnout digispark počkat chvíli a zase ho zasunout?

[nebo]

...USB disconnect, device number 7

je ti jasny, ze pokud behem 2 sekund nezacnes komunikaci tak se bootloader ukonci a zarizeni se zase odpoji?

[and_i]

Ahoj a nema attiny85 chip CH341 misto FTDI?

Asi je treba odpovidajici modul jadra.
