Using a Verdex Pro Gumstix:
Essentially, I want to run this command in Python to control a PCF8574
os.system('i2c 0x38 wb 0x38 0xff') #this command works
However, I need to input a range of hex numbers (0x01 to 0xff) from a Python
variable. Does anyone know how I can change the 0xff to a Python variable
that I can control?
I think it runs along the lines of:
hex = 0xff
os.system('i2c 0x38 wb 0x38 "hex"')
I think I have the logic down, but I don't know how the Python code works
when dealing with embedded Linux commands. Is there even a way to mix
Python with Linux commands like that? Or, is there a better way to access
the I2C bus without using embedded linux commands?
