If not or if you get Error: “AtLibUsbDfu.dll not found” install the drivers manually from the device manager. The device should now show up as Atmega16u2 in the device manager.

Today everybody should have an R3 so no resistor and complicated stuff is needed.

If you have an older Version than the R3 please google how to get in DFU mode. Start Flip.īriefly short these two pins of the 16u2 with a Wire (the jumper is only to show the connection). This will also install the needed DFU drivers to flash the new firmware. You can always switch back to the original firmware, nothing to break.

To install the new bootloader connect your Arduino to your PC and put it into DFU mode. What you need: Arduino Uno/Mega, USB Cable, a normal wire, Flip with Java Flashing new Firmware with DFU and Flip If you have a 8u2 see instructions below the DFU tutorial. This method is called “Device Firmware Upgrade” and also works on Linux/Mac and older versions but its not explained in this article. This tutorial is for Windows and R3 versions only. See for more tutorials and projects Hoodloader Installation on Arduino Uno/Mega R3įor the whole Project IDE 1.5.7 or higher is recommended!

The 16u2 has very few bytes of ram which is very hard to develop with.

15 byte report, 15 report IDs max (by design).

No more Midi/other stuff is possible due to DRAM, RAM and endpoint limitation.

4 pin header needs to be soldered for ISP and additional usage.

8u2 has no ISP function (less flash, use Lite version).

16u2 as ISP has the same functions/bugs like the normal Arduino as ISP.

If you still try to use HID with other baud you will get weird output.

HID only works at baud 115200 (Software and speed limitation, see 'how it works below').

Use the 16u2 as ISP to reprogram your 328 and others.

Serial interface is still usable via USB!.

Program the Arduino Uno/Mega like you are used to.

+++Checkout the new HoodLoader2 which is a fully Arduino IDE compatible bootloader with custom programs and HID core as well.++ It can still work the same but has more functions. The Hoodloader is a fully compatible replacement of the The file-descriptor is set not to block or wait, right? How long does it take to get a response back before you can call read? (It has to be received and buffered by the kernel, through system hardware interrupts, before you can read() it.) Have you considered using select() to wait for something to read()? Perhaps with a timeout?ĭo you need the DTR/RTS lines? Hardware flow control that tells the other side to send the computer data? e.g.This is the source page of the Hoodloader. Just because you don't use ^Q/^S or hardware flow control doesn't mean the other side isn't expecting it.ģ) Most likely: Add a 'usleep(100000) after the write(). Odds are something is incorrect in there. write( USB, 'init ', 5) Ģ) Double check the serial port configuration. Std::cout << 'Response: ' << response << std::endl ġ) I'd add a /n after init. Std::cout << 'Read nothing!' << std::endl Std::cout << 'Error reading: ' << strerror(errno) << std::endl It was definitely not necessary to write byte per byte, also int n_written = write( USB, cmd, sizeof(cmd) -1) worked fine. Open Port int USB = open( '/dev/ttyUSB0', O_RDWR| O_NOCTTY )

I've solved my problems, so I post here the correct code in case someone needs similar stuff. Complete code needs to work in a real-time environment (specifically OROCOS) so I don't really want sleep-like function. Reported one is only an excerpt of my code. Btw, waiting or usleep() is something I need to avoid. Just for a try, I've created a waiting loop until data is avaliable, but my code never exit the loop. I've tried using select() but nothing happens. I've also tried avoiding the O_NONBLOCK flag on reading, but then I only block until forever. Int USB = open( '/dev/ttyUSB0', O_RDWR| O_NONBLOCK | O_NDELAY ) #include // POSIX terminal control definitions

#include // UNIX standard function definitions Here's my code: #include // standard input / output functions Both commands and response are ASCII characters.Įverything works fine using GtkTerm but, when I switch to C programming, I encounter problems.

I need to send those commands and read device's response. I'm working on Linux (Ubuntu).īasically, I am connected to a device which is listening for incoming commands. I'm trying to send/receive data over an USB Port using FTDI, so I need to handle serial communication using C/C++.
