Hi All,
I tried to manage to get the code below started but it's doesn't work. I'm
using the adafruit libary for using the GPIO functions off the beagle bord.
Any one any idea wy the code isn't working?? I try to reach a HX711 adc
chip over the SPI bus.
import Adafruit_BBIO.GPIO as GPIO
import time
DAT = "P9_20"
CLK = "P9_21"
GPIO.setwarnings(False)
GPIO.setup(CLK, GPIO.OUT)
def test():
i=0
GPIO.setup(DAT, GPIO.OUT)
GPIO.output(DAT,1)
GPIO.output(CLK,0)
GPIO.setup(DAT, GPIO.IN)
while GPIO.input(DAT) == 1:
num=0
i=0
for i in range(24):
GPIO.output(CLK,1)
num=num<<1
GPIO.output(CLK,0)
if GPIO.input(DAT) == 0:
num=num+1
GPIO.output(CLK,1)
num=num^0x800000
GPIO.output(CLK,0)
print("test :", num)
while True:
test()
Regards,
Jelle
