I am currently using thePmodAD1 in this mod for signal reception
This is my code
from DesignSpark.Pmod.HAT import createPmod
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
adc = createPmod('AD1','JBA')
point[]
i=0
while i < 1000:
point.append(adc.readA1Volts())
plt.xlim(0,100)
plt.ylim(0,5)
plt.plot(point)
plt.show()
I use this code when I input more than 1Khz sine wave, my waveform will start to become malformed, I know it is the relationship of the sampling rate is not enough, but I have adjusted the mod spi_max_speed to 12Mhz But no matter what The waveforms are still the same
It is said that it is the limitation of the linux spi driver. I counted the points, and my sampling rate is almost 20k.
Excuse me, if I want to get the complete 40k and 40khz waveforms, store the points of the waveforms in the matrix, and export the matrix to .csv, how can I do it with python?
forgot to type in the sample rate I needed I need a sample rate of at least 384khz The raspberry pi I am using now is raspberry pi 3b Linux Kernel is version 5.15.32-V7 The ADC part is directly plugged into the module, I don't know how his pins are connected
