Goodday,
Something strange going on here.
A piece of code I wrote bombs out in one of de directories under $HOME,
but not in others.
Here's a snipped:
#v+
def bin2asc(c):
s=''
for i in range(0,8):
if c & 1<<(7-i):
s+='1'
else:
s+='0'
return 'b'+s
def shiftout(numoctets):
os.system('clear')
ser = serial.Serial(0)
from array import array
octarray = [0]
for i in range(0,numoctets-1):
octarray.append(0)
for octet in range(numoctets,0,-1):
octarray[octet-1]=1
for shift in range(0,8):
strg = array("B",octarray).tostring()
for oct in range(len(strg)):
print 'octet%-11s' % oct,
print
for byte in array("B",octarray):
print '%-2s' % bin2asc(int(byte)),
print '%-6s' % hex(int(byte)),
print; print
try:
dummy = raw_input("Druk op een toets om de bytes te verzenden ")
except KeyboardInterrupt, msg:
print; usage("Exiting..")
sys.exit()
ser.write(strg)
octarray[octet-1] = octarray[octet-1] << 1
os.system('clear')
octarray[octet-1]=0
print "done..

Here's the output from the directory it bombs out in:
#v+

Where the numbers come from I don't know, python internal?

Now i've made hard links to other directories, like $HOME and $HOME/bin
#v+
theo:/home/theo $ stat serialLEDtest-cli.py

And when I run (the same script) from that location:
#v+
theo:/home/theo $ python serialLEDtest-cli.py
Hoeveel chips van het type HC595 zitten er op het LED board? 2
octet0 octet1
b00000000 0x0 b00000001 0x1
Druk op een toets om de bytes te verzenden
#v-
Not a problem there, and neither in other directories I made links in,
or copied the file to, only in that one directory..
Anyone have ideas?
Tnx.
Theo
