The whole concept of Baud Rate with USB communication is completely meaningless. There is no such thing as "baud rate" over USB.
What there is, and what you are confusing with "baud rate" is a configuration item which the host can send to the device which is a "I would like you to communicate with other devices at this speed" configuration item.
This is ...
The command format is simple, assuming you have installed it from the Linux repositories:
avrdude -carduino -patmega328p -P/dev/ttyUSB0 -b115200 -Uflash:w:/path/to/project.bin.hex:i
Depending on what bootloader is installed in your nano you may need to change the baud rate (-b115200) to 57600. Also, of course, the USB device should be set to ...
You can use Eclipse, along with AVR-GCC and AVRDude and an AVR plug-in for Eclipse. Debugging may be a little painful since you don't have all the tools that Atmel Studio gives you. I'd question your employer if you aren't allowed to use the best (free) tools even if they do run on Windows.
Really all you need is the avr-gcc and avrdude to write software ...
For those that hit the same issue, here is how I solved it:
Expose the USB_SendSpace() information in the HID interface by editing
And adding the interface to class HID_ in:
I have to sadly conclude that this issue posted was for nothing. the board I was using most likely has an underlying defect (of all odds, the 45 boards my teacher was using, he gives me 1 defect board? believable.) rendering the board inoperable. I plugged the board into an entirely different laptop, downloaded and installed a full IDE for it, ran it ...
In the Arduino IDE, the mcu will show up in Tools > Port.
Your Arduino Nano will probably be visible at /dev/ttyUSB0 or /dev/ttyUSB1 following whatever is already plugged on USB. Make sure to select it.
Select Nano in Tools > Board.
Last step is Verify/Compile your code (^R), then Upload (^U).
This link sounds to be a good read to start.
I use the Arduino IDE to 'build' everything.
However, in case of a bigger project, I use a 'decent' code editor (Visual Studio in my case) to edit, and the Arduino IDE to build.
Also, because I prefer testing all non-Arduino related code on the PC (not on the Arduino), the Visual Studio (C++) project uses some stub classes I created (specifically for my ...
You mean that the STK500 v2 programmer uses an emulated serial port
rather than direct USB? Then I guess there is a bug in the Arduino IDE.
The file programmers.txt contains the following lines
describing the programmer:
An Arduino boards package with configuration for your board has constants for pins which correspond to labels on the PCB. The constants are defined in pins_arduino.h file, which is applied only if you choose the corresponding board in Tools menu. In code you should use this constants as values for your constants, like for example const uint8_t LED1_PIN = D2;....
I will put our comments together in an answer.
You are overthinking the security issue. In my opinion, using RFID to reset the system is a bigger security thread, than using ssh the correct way. Normal RFID chips are susceptible to spoofing (copying an existing chip). Also the intruder could remove the RFID module to directly access the communication lines (...
