问题描述

我使用 AVRDUDE 为Android(的 HTTP://$c$c.google.com/p/andavr/ )。我可以编译ç code。我可以运行

I am using AVRDUDE for Android (http://code.google.com/p/andavr/). I can compile the C code. I can run

$ avr-gcc -Os -DF_CPU=16000000UL -mmcu=atmega328p -c -o led.o led.c
$ avr-gcc -mmcu=atmega328p led.o -o led
$ avr-objcopy -O ihex -R .eeprom led led.hex

都没有问题。然后我尝试运行:

all without issues. Then I try to run:

avrdude -F -V -c arduino -p ATMEGA328P -P /dev/bus/usb/002/002  -b 115200 -C /data/data/jackpal.androidterm/local/etc/avrdude.conf -U flash:w:led.hex

结果是:

avrdude: ser_open(): can't open device "/dev/bus/usb/002/002"; Permission denied
loctl("TIOCMGET"): Invalid argument

avrdude done. Thank you.

的情况是类似的,当我运行:

The situation is similar when I run:

avrdude -F -V -c arduino -p ATMEGA328P -P /dev/bus/usb/002/001  -b 115200 -C /data/data/jackpal.androidterm/local/etc/avrdude.conf -U flash:w:led.hex

我可以证实,的/ dev /巴士/ USB / 002/002 OTG 电缆。在连接之前,我跑

I can confirm that /dev/bus/usb/002/002 is the Arduino device connected with the OTG cable. Before connecting, I run

ls -l /dev/bus/usb/002/

和我得到的:

total 0

在我通过USB我的平板电脑连接的Arduino我运行命令:

After I connect the Arduino via USB to my tablet I run the command:

ls -l /dev/bus/usb/002

和我得到

crw-rw----   1 0   1018  180,128 Mar 24 07:53 001
crw-rw----   1 0   1018  180,129 Mar 24 07:53 002

这清楚地表明我的Arduino的连接。我很想知道,如果任何人都可以看到我在做什么错。

This clearly shows me that the Arduino is connected. I would love to know if anyone can see what I am doing wrong.

PS:我想创建一个Android应用程序,可直接从Android平板电脑的Arduino编程

PS: I am trying to create an Android application that allows Arduino programming directly from an Android tablet.

推荐答案

报告说,权限被拒绝',你似乎没有使用一个root shell。 尝试素,然后该命令失败。如果您的手机是不是扎根,我不认为它可以工作。

It says 'permission denied' and you do not seem to be using a root shell. Try 'su' and then the command that failed. If your phone is not rooted, I don't think it could work.

我甚至不知道这是否会工作的时候,当你的根,所以请后的结果!我的猜测是,它不会,如果你的手机不作为USB主机(只有一些可以)

I'm not even sure if it will work right when you are root, so please post the result! My guess is that it won't if your phone does not act as usb host (only some can)
