NodeMCU uploading problems

-

hello,
i've tried uploading code in modemcu esp-12 0.9 (v1) when upload code (it's blink code took examples), have following errors , warnings:
warning: espcomm_send_command: wrong direction/command: 0x00, expected 0x01 0x08
warning: espcomm_send_command: wrong direction/command: 0x00, expected 0x01 0x08

warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

i use linux 16.04 lts (32 bits)
i use arduino 1.6.13
i use nodemcu esp-12 0.9 (aka v1)

and tried:
-d0 rst or gnd
-gpio0 rst or gnd
-flash button
-changing usb cable

thanks, sick , tired of problem (i spent day yesterday).

help !

i'm struggling dht11 sensor work on arduino. code compiles without problems in serial monitor output keep on getting " read sensor: time out error" i've tried multiple libraries, adafruit etc still none of them worked. set serial monitor same speed (115200) didn't fix problem.  i'm using:  mega2560  dht11 temp+hum sensor windows10 x64 arduino 1.6.9 library dht11.h v0.4.1 source:  http://playground.arduino.cc/main/dht11lib wiring : blue = gnd yellow = 2 red = 5v (also see picture)  my code:    code: [select] #include <dht11.h> // //   file:  dht11_test1.pde // purpose: dht11 library test sketch arduino // //celsius fahrenheit conversion double fahrenheit(double celsius) {   return 1.8 * celsius + 32; } // fast integer version rounding //int celcius2fahrenheit(int celcius) //{ //  return (celsius * 18 + 5)/10 + 32; //} //celsius kelvin conversion double kelvin(double celsius) {   return ...

hi, i'm getting same error despite have tried 2 boards , done arduino reinstall in windows 7 machine! while trying update "bareminimum" in verbose mode: code: [select] arduino: 1.8.0 (windows 7), board: "arduino/genuino uno" sketch uses 450 bytes (1%) of program storage space. maximum 32256 bytes. global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes local variables. maximum 2048 bytes. ___remove___/bin/avrdude -c___remove___/etc/avrdude.conf -v -patmega328p -carduino -pcom8 -b115200 -d -uflash:w:c:\users\rui\appdata\local\temp\arduino_build_445303/bareminimum.ino.hex:i java.io.ioexception: cannot run program "___remove___/bin/avrdude": createprocess error=2, system cannot find file specified  at java.lang.processbuilder.start(processbuilder.java:1048)  at processing.app.helpers.processutils.exec(processutils.java:26)  at cc.arduino.packages.uploader.executeuploadcommand(uploader.java:129)  at cc.arduino.p...

hi, sorry, new , unsure lot of things, need clarification. haven't found information explains how , why things work, "do this, that" i following guide ( arduino-thermistor-temperature-sensor-tutorial ) connect thermistor arduino uno. here temperature sensor information: temp. sensor 2000r +-1% to92 part.no.:   kty81-210 name:   temp. sensor 2000r +-1% to92 description:   2.5mm, 1980...2020ohm, -55...+150°c and here sensor's data-sheet: sensor data-sheet i have connected same way in guide. works , values being serial printed. what don't understand: 1. thermistor's , resistor's ohm value should equal, correct? in case 2000 ohm? 2. thermistor has ptc, i'm guessing have invert math or use ntc thermistor instead correct values? (currently resistance goes temperature goes down) 3. understand code uses steinhart-hart math logic convert resistor value temperature value, need a, b , c coefficients of thermis...
