Rob, It appears that I missed this in the description. Probably because I was following the lead of the ts2005 description. How does this look: - reg : I2C address. 0x48 - 0x4b based on the voltage applied to the AD1 and AD0 inputs on the IC. Do I have to spin the whole series to update this patch? Everyone, Are there any other concerns with this patch series?
