Starterware/TCA6416: TCA6416 Acknowledge failure

user4646208

Part Number: TCA6416

Tool/software: Starterware

I am trying to appeal to TCA6416, but the problem is that it does not respond to ASK.
I check the whole l2c bus in cycle and TCA6416 is the only thing that is not seen there.
I also have TCA6416 and i have the same problem with it.

Here's a sample code:

uint8 i2cWriteBuffer[2] = {0x06, 0x00};
I2C_Transmit(0x20 << 1, (uint8*)i2cWriteBuffer, 2);

Hello user4646208,

I am having a hard time understanding your question. Are you saying that you aren't getting an ACK when communicating to the TCA6416 device? Do you have a schematic of the design along with capture of I2C waveforms?

Also, have you considered using the TCA6416A instead. The TCA6416 has a couple errata issues that are fixed in the A version of the device.
