I am trying to communicate with my Synaptics touch pad. I am using
FreeBSD which doesn't have a setup program available. I have all of the
relevant command data, so I'm trying to make something work in Python.
However, I am confused about how to send binary bytes to the device.
Here is the code that I tried:
tp=open('/dev/psm0','wb+') #open device
tp.write(`0xff`) #reset touchpad
print tp.read() #read ack
But I always get an error message, "OSError- Operation Not Supported".
I'm not quite sure how to take a binary byte 0xff, and feed it into the
write() command. It seems that `0xff` may be the problem. How do I
accomplish this? Thanks.
