Internal I2C single Byte Read

sarvraj_5 — Thu, 03 Jan 2019 13:16:25 GMT

I am trying to communicate with FXLS8962 accelerator with S12ZVL32 starter kit.

For drivers i am using the InternalI2C with processor expert.

In order to do operations :

However I am not able to read WHO AM I register 13.

The slave address is 18 whrn SA0 = GND.

As on can see, I send the start, device address with write, receive ACK. then the register to read, THen repeated start and device address with read bit , then i dont receive anything in the I2C bus.

Hi,

I don't see the clock of the read byte.

If you disconnect the master from the bus, is the bus hold by the slave low?

Can you share your code?

Anyway, you can use the attached example, the S12ZVC MCU has the same IICV3 module.

Regards,

Daniel
