Looking for an easy implementation of a Kalman filter... in case this is a valid enhancement idea/request
Hi Peter,
I try fir.py with MicroPython 1.17 on NUCLEO-L476RG board.
There is a problem only when the number of coefficients is a multiple of 4.
For exemple :
coeffs = array.array('i', (100, 100, 100, 100))
ncoeffs = len(coeffs)
data = array.array('i', [0]*(ncoeffs +3))
data[0] = ncoeffs
data[1] = 0
fir(data, coeffs, 1) # 100 OK
fir(data, coeffs, 0) # 100 OK
fir(data, coeffs, 0) # 100 OK
fir(data, coeffs, 0) # 134492960 bug
coeffs = array.array('i', (0, 100, 100, 100, 100)) works !
I am trying to make an lpf FIR filter run on my pico pi. I use VS code and the examples from your filter project. In VS Code I am not able to get rid of the import error on "from fir import fir". Reading several days on internet, I read a lot concerning import problems. Local imports seem to be a trouble on VS Code, so mine do as well! Do somebody know a solution? I tried extra python paths, ini.py file etc. Nothing advised on the internet makes this local import possible. However, in Thonny it works (after saving fir.py to the pico pi). My python is 3.10.2 and my VS code is 1.71.2 + PYLANCE, PICO-W-GO. Can somebody hint me?
