I made the code for the z axis of the accelerometer but i just need some
help on how to adjust it for the X and Y axis. Heres the sample code for
the z axis.
import smbus
import time
def main():
bus = smbus.SMBus(1)
# Power-on the accelerometer, enabling only the z-axis
bus.write_byte_data(0x18, 0x20, 0x24)
try:
while True:
# get z-axis acceleration
tilt = bus.read_byte_data(0x18, 0x2D)
# if it's supposed to be negative
if tilt > 127:
# then convert it to the absolute value of the negative value
tilt = 256 + ~tilt
positive = False
else:
positive = True
# format and print it
pos = tilt / 2
print str(tilt).rjust(6),
if positive:
print 65*' ' + '|' + (pos*'#').ljust(65)
else:
print (pos*'#').rjust(65) + '|' + 65*' '
# sleep
time.sleep(0.1)
except KeyboardInterrupt:
# restore default settings
bus.write_byte_data(0x18, 0x20, 0x07)
if __name__ == '__main__':
main()
I only need an idea for the X and Y axis. Thanks to anyone who can help.
