hello there, I have two Raspberry Pi Picos, both are giving me the same error without even running the code. Traceback (most recent call last): File "<stdin>", line 7, in <module> TypeError: function takes 0 positional arguments but 2 were given WARNING: Could not sync device's clock: function takes...

HI,

I'm working on stepper motor, I have three same kind of stepper motor connected to "pico". I need to merge all these individual codes into one single code and run the motor simultaneously.

Thankyou so much for your help, it's all done.

without you may be we can't do it. thanks a lot

we are using 1kg strain gauge load cell.

sorry to bother you again, but I need some clarity on calibration thing. so, when I am running example_rp2_test.py file it's printing the value continuously with different numbers and simultaneously, i am getting one value when running scale.py file (this is without load) lly, when applied load the ...

yes, it worked..

Thank you so much for that 3.3v, we fixed it and getting the values

can we know how to calibrate the values, I have attached scale.py offset values which is -404751.

can you please help with that thing too, it would be so great if you could help with this.

I tried adding the code in the while loop which you gave, but getting the same zeros in the output.

I need the weight of the product as the output but it's showing all zeros.

okay,
can you please elaborate what I should keep inside the while loop in order to print the weights?
and to print the new values.

Hello, yes, thanks for your reply. I have changed the pin connection in the code and when i am trying to calibrate it's not working when i am running the example_rp2_test.py file , it giving me all zero's and when i am running scale.py file, it gives me a error saying type object 'SPI' has no attrib...

hello there, This is the schematic diagram for the load cell with pico. this could give you a clear understanding of the connections. I'm keeping the code as well for your reference. from hx711_gpio import HX711 from machine import Pin pin_OUT = Pin(12, Pin.IN, pull=Pin.PULL_DOWN) pin_SCK = Pin(13, ...
