adafruit-nrfutil is a modified version of Nordic's nrfutil, which is used to flash boards using the built in serial bootloader. It is originally written for python2, but have been migrated to python3 and renamed to adafruit-nrfutil since BSP version 0.8.5.
Usb Library Version 030207
This is probably caused by the bootloader version mismatched on your feather and installed BSP. Due to the difference in flash layout (more details) and Softdevice API (which is bundled with bootloader), sketch built with selected bootloader can only upload to board having the same version. In short, you need to upgrade/burn bootloader to match on your Feather, follow above Update The Bootloader guide
This is probably caused by a conflict between 32-bit and 64-bit versions of the compiler, libc and the IDE. The compiler uses 32-bit binaries, so you also need to have a 32-bit version of libc installed on your system (details). Try running the following commands from the command line to resolve this:
The Bluefruit nRF52 Feather includes a customized version of the Nordic bootloader that enables serial support, over the air (OTA) DFU support, and various fail safe features like factory reset when the FRST pin is grounded at startup.
Therefore latest BSP release could support newer SoftDevice version than one currently exists on your board. Due to the flash memory & API difference between SoftDevice major versions, upgrade your board's bootloader to match one supported by BSP is required to upload compiled sketch. Luckily the Bluefruit nRF52 Bootloader can be upgraded/downgraded without any additional hardware, and we can even do that right in Arduino IDE without at risk of typos or common user errors.
Next, select Communication from the topic dropdown, and enter MIDI Library into the search box. Click the Install button to install version 4.3.0 or higher of the MIDI Library.
The full source code for Bluefruit LE Connect for Android is also available on Github to help you get started with your own Android apps. You'll need a recent version of Android Studio to use this project.
This utility performs automatic firmware updates similar to the way that the GUI application does, by checking the firmware version on your Bluefruit device (via the Device Information Service), and comparing this against the firmware versions available online, downloading files in the background if appropriate.
It runs on OS X, Windows 7+ and select flavours of Linux (Ubuntu tested locally). Windows 7 support is particularly interesting since Windows 7 has no native support for Bluetooth Low Energy but the noble library talks directly to supported Bluetooth 4.0 USB dongles to emulate BLE on the system (though at this stage it's still in early BETA and drops the connection and takes more care to work with).
It currently supports using either a Segger J-Link or STLink/V2 via AdaLink, or GPIO on a Raspberry Pi if you don't have access to a traditional ARM SWD debugger. (A pre-built version of OpenOCD for the RPi is included in the repo since building it from scratch takes a long time on the original RPi.)
After you have downloaded and installed the latest version of Arduino IDE, you will need to start the IDE and navigate to the Preferences menu. You can access it from the File menu in Windows or Linux, or the Arduino menu on OS X.
Each TC instance has one count register, one control register, and two output channels. Either channel can be enabled and disabled, and either channel can be inverted. The pins connected to a TC instance can output identical versions of the same PWM waveform, or complementary waveforms.
Like the AVR Arduinos, the M0 library does not have full support for converting floating point numbers to ASCII strings. Functions like sprintf will not convert floating point. Fortunately, the standard AVR-LIBC library includes the dtostrf function which can handle the conversion for you.
Unfortunately, the M0 run-time library does not have dtostrf. You may see some references to using #include to get dtostrf in your code. And while it will compile, it does not work.
There's a lot of registers on the SAMD21, and you often are going through ASF or another framework to get to them. So having a way to see exactly what's going on is handy. This library from drewfish will help a ton!
These radios have really great libraries already written, so rather than coming up with a new standard we suggest using existing libraries such as LowPowerLab's RFM69 Library and AirSpayce's Radiohead library which also suppors a vast number of other radios
Rename the uncompressed folder RadioHead and check that the RadioHead folder contains files like RH_RF69.cpp and RH_RF69.h (and many others!)Place the RadioHead library folder in your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if it's your first library. Restart the IDE.We also have a great tutorial on Arduino library installation at: -all-about-arduino-libraries-install-use
OK so the basic demo is well and good but you have to do a lot of management of the connection to make sure packets were received. Instead of manually sending acknowledgements, you can have the RFM69 and library do it for you! Thus the Reliable Datagram part of the RadioHead library.
It's easy to use the RFM69HCW radio with CircuitPython and the Adafruit CircuitPython RFM69 module. This module allows you to easily write Python code that sends and receives packets of data with the radio. Be careful to note this library is for the RFM69 radio only and will not work with the RFM9X LoRa radios!
Alternatively you can use the Feather M0 RFM69 board but be sure you've loaded the adafruit-circuitpython-feather_m0_rfm69-*.bin version of CircuitPython on your board! This is very important as the RFM69 build has special pins added to the board module which are used to access the radio's control lines!
If you have the Feather M0 RFM69 and have installed CircuitPython 6.0 or later, it is not necessary to install the library modules. They are "frozen into" the Circuitpython build. Skip to the "Usage" section below.
Next you'll need to install the Adafruit CircuitPython RFM69 module on your CircuitPython board. Before you do that make sure you are running the latest version of Adafruit CircuitPython for your board too (again be sure to the load the Feather M0 RFM69 version if you're using that board and want to use its built-in radio module).
Next you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install these libraries from Adafruit's CircuitPython library bundle. Our introduction guide has a great page on how to install the library bundle for both express and non-express boards.
However if you're using the Feather M0 RFM69 board with a built-in RFM69 radio (and you've loaded the special version of CircuitPython just for this board as mentioned above), you instead want to use these pins for the CS and RST lines:
You can even have an Arduino running the RadioHead library's raw RX example see the message that was sent (be sure this receiving side has an encryption key setup exactly the same way as the sending side, see the encryption_key property discussion further below):
Notice this waits longer at the REPL for a packet to be received before returning. If you have another RFM69 setup try having it send a message while the other is waiting to receive it. You should see a byte string returned. You can also have an Arduino running the RadioHead library's raw TX example send messages that are received by your code (again it must be setup with the same encryption key):
Bonjour Assez nouveau sur VCDS, je l'ai acheté cable et logiciel (en version 12-12).on l'installant sur PC Windows 7 64 bits , il me signale que la version 12.12 est PERIMEE ,qu'il faut charger la version 16.8.0, ce que je fais. Mais une erreur apparait et je ne voie pas comment la résoudre:"etat port COM ; Okversion librairie USB;03.02.07version pilote USB : 02.10.00Interface : non trouvée"Avec la version 12.12 j'ai réussi à me connecter à l'interface et relever des défauts, mais pas la 168.0.Alors si quelqu'un sait, merci par avance .
Because Intel PT is a hardware feature, you need hardware that supports it, and also a Linux kernel that has support. Support was added to Linux in version 4.2 and nowadays, most Linux distributions have a kernel more recent than that, so the simple way to tell whether you can use Intel PT is to check whether the directory /sys/devices/intel_pt exists.
The online perf Intel PT man page is not necessarily the latest version, however the wiki has a copy which may be more uptodate: perf Intel PT man page. Also the man page source in the Linux repository is quite readable: perf Intel PT man page source 2ff7e9595c
