Device is busy or does not respond ESP32 !!!!!
Posted: Thu May 19, 2022 10:20 am
Hello always the same !!!!
The first steps are difficult !!!
I use a "MakePython ESP32 Development Kit "
The last program i have done is a program with a temperature sensor DS18B20 and a oled display SSD1306 witch use the OneWire protocol , the program work well
After that i try to use a ultrasonic sensor HC_SR04 .....and my first step ......i writte these 2 lines :
from machine import Pin
pulse_out = Pin(3,Pin.OUT)
....then run the biggest program (to debug .....?)......BUT IMPOSSIBLE the message return is
***********************************************************************
Device is busy or does not respond. Your options:
- wait until it completes current work;
- use Ctrl+C to interrupt current work;
- reset the device and try again;
- check connection properties;
- make sure the device has suitable firmware;
- make sure the device is not in bootloader mode.
Could not interrupt current process. Please wait, try again or select Stop/Restart!
***********************************************************************
Then I try all the method described ......always the same message !
I disconnect the board and reconnect it ....i try to open files in the board but IMPOSSIBLE ...board BUSY , reset ,Crtl_C, Stop,....,put away all components on the board .....the only thing i don't know is "- make sure the device is not in bootloader mode. "
I reduce my program:
from machine import Pin
and try to run it, same message
I know i can install the firmware again but it's not a great solution !!!!!!
Thanks very well for all help
Best regards
Can you help me I'm in a wrong way........
