kipcrossing / micropython-ad9833 Goto Github PK

Hi ,I used Raspberry Pi and set up spi and ss pins, and changed spi.send(to_send) to spi.xfer(to_send), still got error, wave.send()，An error occurred,Please guide.

My code

from ad9833 import AD9833
import spidev
import RPi.GPIO as GPIO

pin_id=7

def get_RPi_spi(mode = 0b10, lsbfirst = False):

spi = spidev.SpiDev()
spi.open(0, 0)
spi.max_speed_hz = 9600
spi.mode = mode
spi.lsbfirst = lsbfirst
return spi

GPIO.setmode(GPIO.BCM)
_ss = GPIO.setup(pin_id, GPIO.OUT)
_spi = get_RPi_spi

wave = AD9833(_spi,_ss)

wave.set_freq(14500)

wave.set_type(0)
wave.send()
print(wave.shape_type)
print(wave.freq)

Traceback (most recent call last): File "/home/a123456/Desktop/Micropython-AD9833-master/AD9833-TEST.py", line 31, in
wave. send()

self . ss.low()

Hi , i am not able to install the pyb library. Because of this issue, i am not able to use the ad9833 ic. Please guide.

Heya Kip!
I'm having some issues with running this on Raspberry Pi Pico.

My code is:

from machine import Pin, SPI
from ad9833 import AD9833

spi = SPI(1, baudrate=9600, polarity=1, phase=0,firstbit=SPI.MSB)
ss = Pin(0, Pin.OUT, Pin.PULL_UP)

wave = AD9833(spi, ss)

wave.set_freq(14500)
wave.set_type(0)
wave.send()
print(wave.shape_type)

and I’m getting this error message:
Traceback (most recent call last): File "<stdin>", line 11, in <module> File "ad9833.py", line 57, in send File "ad9833.py", line 20, in _send AttributeError: 'SPI' object has no attribute 'send'
P.S I'm new to both Raspberry Pi Pico and Python I'm sorry if it’s a very basic question.
