Be careful with start/end arguments, if they are out of range (0..15) you will have mysterious problems.

Member TLC59116::allcall_address (byte address, bool enable=true)

However, the TLC59116Manager.broadcast() object only assumes the default allcall_address 0x68. So, it won't work if you change the allcall_address.

Member TLC59116::SUBADR_address (byte which, byte address, bool enable=true)

We don't track commands on SUBADR_n's, so this library will get very confused about the state of the devices and do confusing things if you mix broadcasts to SUBADR_n devices, and individual devices in that SUBADR_n group.

Also, this library provides no easy access to broadcast to a SUBADR_n group.

Class TLC59116Manager

This collects all I2C devices between 0x60 and 0x6E. Non TLC59116 devices can appear in our list! The TLC59116 doesn't have a feature that identifies it, so we just assume.
