The pyserial-2.4-py2.7.egg in the site-packages folder was getting imported instead of from serial in the site-packages folder. Once I renamed this file so that it no longer imported from this it worked fine. You can easily debug this by doing
Just in case that doing "pip install --upgrade" doesn't work(as happened to me), in Linux you can check if you have a serial package in /usr/lib/python2.7/dist-packages, the new serial packaged the one that pip install goes to /usr/**local**/lib/python2.7/dist-packages/serial, for some reason the one in usr/lib/python2.7/ has precedence and the module tools doesn't exist in that version of pyserial. Changing names or deleting the directory solve the problem.
Recent versions of ATLAS can be built as a single shared library, eitherlibsatlas or libtatlas (serial or threaded respectively):these may even contain a full LAPACK. Such builds can be used by one of
The IMEI (15 decimal digits: 14 digits plus a check digit) or IMEISV (16 decimal digits: 14 digits plus two software version digits) includes information on the origin, model, and serial number of the device. The structure of the IMEI/SV is specified in 3GPP TS 23.003. The model and origin comprise the initial 8-digit portion of the IMEI/SV, known as the Type Allocation Code (TAC). The remainder of the IMEI is manufacturer-defined, with a Luhn check digit at the end. For the IMEI format prior to 2003, the GSMA guideline was to have this Check Digit always transmitted to the network as zero. This guideline seems to have disappeared for the format valid from 2003 onwards.
Select the port that your ESP2866 is on. In this example it is COM4. Make sure that you have closed all other serial monitors that may be on this port. Eg: The Arduino one, or CoolTerm etc.. The firmware flasher will not work otherwise.
Beware that this installation method needs a TTL level serial console usb to TTL like DKU-5 data cable or RS232-TTL level shifter like this: and a working TFTP server and should not be attempted unless you have experience with this sort of thing or are eager to learn.
Hmm... can you add "-v -v -v -v" to the end of the avrdude command line command and post the full output (when it doesn't work)? What sketch are you uploading? Try one that doesn't do any serial communication.
i can wait (i tested 30 minutes now), it seems not depending on the time.If i upload a sketch with serial communication the sketch AND the communication are working fine constantly.The upload problem appears even if i use a sketch without any serial communication.
Hmm, my guess would be that the auto-reset of the Diecimila isn't being triggered by avrdude after the first time. The Arduino IDE explicitly toggles the DTR line before uploading (which resets the board) whereas using avrdude from the command line relies on the fact that the standard Linux driver for the FTDI chip sets DTR when you open the serial connection. It is, however, possible to set a bit on the port (HUPCL) that prevents the line from being reset when you close the connection, meaning that nothing happens to the line when you re-open the connection (i.e. the board doesn't get reset). I don't know why/how HUPCL would be getting set, but it's possible (maybe the FTDI driver for your kernel works differently than the ones I've tried).
thanks for this DTR pulse tip! Here is a slightly enhanced version of the Perl code, that automatically determines the serial port from the -P avrdude parameter and calls the avrdude program after the DTR pulse. Rename the original avrdude to avrdude.org and store the Perl script under the name avrdude. Don't forget to make it executable.
The Bus Pirate is accessed from a command line in a serial terminal. The Bus Pirate always starts in high impedance mode (Hi-Z), a safe mode with all outputs disabled. It's intended to protect any connected devices from conditions beyond their specifications. From there, a bus mode can be selected to use the Bus Pirate with a specific protocol.
The Bus Pirate is a slow serial port device intended for human-speed interaction. It was NEVER intended to do JTAG duties. Because it's open source, cheap, and versatile, the community hacked various JTAG features into it. They're great in a pinch, but no substitute for the real thing!
bpo-46906: Add new functions to pack and unpack C double (serialize anddeserialize): PyFloat_Pack2(), PyFloat_Pack4(),PyFloat_Pack8(), PyFloat_Unpack2(),PyFloat_Unpack4() and PyFloat_Unpack8(). Patch by VictorStinner.
The detection of serial ATA (SATA) devices is somewhat crude andis performed after checks are made for more traditional SCSItransports. The identification of an SATA transport is made on thebasis of the low level driver name that the device or host uses. Asimilar mechanism is used to detect parallel ATA devices andthere is some overlap since some drivers support both SATA and PATAdevices. No other attributes are provided. See the example in the ATAsection, specifically device 0:0:0:0 and the associated host0.
A record contains a header and a body, in that order. The header begins with a single varint which determines the total numberof bytes in the header. The varint value is the size of the header inbytes including the size varint itself. Following the size varint areone or more additional varints, one per column. These additional varintsare called "serial type" numbers anddetermine the datatype of each column, according to the following chart:
The header size varintand serial type varints will usually consist of a single byte. Theserial type varints for large strings and BLOBs might extend to two or threebyte varints, but that is the exception rather than the rule. The varint format is very efficient at coding the record header.
The values for each column in the record immediately follow the header.For serial types 0, 8, 9, 12, and 13, the value is zero bytes inlength. If all columns are of these types then the body section of therecord is empty.
It is now possible to monitor deserialization of objects using JDK Flight Recorder (JFR). When JFR is enabled and the JFR configuration includes deserialization events, JFR will emit an event whenever the running program attempts to deserialize an object. The deserialization event is named jdk.Deserialization, and it is disabled by default. The deserialization event contains information that is used by the serialization filter mechanism; see the ObjectInputFilter specification. Additionally, if a filter is enabled, the JFR event indicates whether the filter accepted or rejected deserialization of the object. For further information about how to use the JFR deserialization event, see the article Monitoring Deserialization to Improve Application Security. For reference information about using and configuring JFR, see the JFR Runtime Guide and JFR Command Reference sections of the JDK Mission Control documentation.
java.util.Vector is updated to correctly report ClassNotFoundException that occurs during deserialization using java.io.ObjectInputStream.GetField.get(name, object)when the class of an element of the Vector is not found. Without this fix, a StreamCorruptedException is thrown that does not provide information about the missing class.
Allow applications to configure context-specific and dynamically-selected deserialization filters via a JVM-wide filter factory that is invoked to select a filter for each deserialization stream. The behavior is a strict subset of JEP 415: Context-Specific Deserialization Filters to allow a filter factory to be configured using a property configured on the command line or in the security properties file.
The behavior is opt-in based on the presence of the jdk.serialFilterFactory system property on the command line or the jdk.serialFilterFactory security property. If set, the JVM-wide filter factory selects the filter for each stream when the stream is constructed and when a stream-specific filter is set. 2b1af7f3a8
