Hello Guys,

Looking at the LPC800-MAX schematic, the PWM's are from an I2C device, PCA9672
this is a port expander chip,
I have looked at the data sheet, but there is a distinct lack of information,
as far as i can see, there is not even a resistor map !!

The prelude of the data sheet implies, that 'FAST I2C Interface', so I guess you 'BIT BASH' PWM :(

Sorry, not much help.
