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........
Device is busy or does not respond ESP32 !!!!!
Re: Device is busy or does not respond ESP32 !!!!!
What firmware are you loading on this device?.I know i can install the firmware again but it's not a great solution !!!!!!
Try this simple program:
Code: Select all
import utime
print ('at least I got this far')
utime.sleep(5)
Re: Device is busy or does not respond ESP32 !!!!!
How about running a smaller program and getting that to work first. How BIG is this biggest program?....then run the biggest program
Re: Device is busy or does not respond ESP32 !!!!!
I'm very happy for your answer i don't know how to resolve this problem
I can't do nothing .......
I try to reproduce this problem
i install again the firmware
i download a simple program "Flashing Led" as main.py in the board ===>OK
i download ssd1306.py on my board
i download as main.py my program with the temperature sensor DS18B20 with oled Display SSD1306 protocol OneWire ==>OK
i create a new program very long as you can see
from machine import Pin
i execute it (interpreter ) ===> OK no but !!!!!!!!!!!!!!
i TRY to download it in the board but always message "Board busy" IMPOSSIBLE to stop it
I retry again import firmware...and so one.....and NOW IT'S OK !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I thank you very much, there is some trouble on my board ??? , the same protocol but not the same issu
Best regards

Re: Device is busy or does not respond ESP32 !!!!!
Hi. I have basically the same sort of out of the box experience.
I got the makePython ESP32 Development Kit oled because the screen looks beautiful.
I also could not get a prompt at first. I needed to flash to the latest version of Micropython.
Now I can and I can use the wifi, BUT I cannot use the oled with the provided steps from the vendor.

I have contacted their tech support today. Maybe they can help you as well?

Re: Device is busy or does not respond ESP32 !!!!!
I received a reply from tech support. In short was using the wrong driver, the right one worked (color):
Sorry it's not the same issue. I was trying to help
Code: Select all
The ssd1306 code runs on MakePython ESP32 not ESP32 Color LCD

You can get the code runs on ESP32 Color LCD from our wiki:
