Other Parts Discussed in Thread: TCA9538, , TCA9534
Hello,
I've on my board 2 tcs9534A and I try to discuss with them at adress 0x20 and 0x21 without any results.
These adresses are in the datasheet page 19 table 2.
I consults some of your forum and I have read than some customers have an identical issue. The parts respond to address 0x38.
I try these adresses 0x38 and 0x39, now your tca9538 answer.
Please con you explaine why the datasheet give address 0x20 and we have to send address 0x38.
Thanks a lot
