Hi,
I have A0~A2 connected to the ground, but TLC59208F doesn't ack when I send the I2C commands. Is there anything I need to do before I can use 0x40 as the slave address?
regards,
Kevin

Kevin,
There is nothing you need to do before using 0x40 to address the device. I would suggest one thing. The bit pattern for GND, GND, GND is: 0 1 0 0 0 0 0 R/W.
Depending on how you interpret the R/W, it may require 0x20 for the register to ack. I have used some software that requires 0x20 and some that requires 0x40. The information is sent correctly, but depending on the system I use it may or may not include the R/W bit.
Regards,
Dick
