Hi all I am using the i2C IP Core. In NIOS i would like to get data from an Bosch BME280.

Now i get (console output) always the same value, nothing changes.. Also not if i try to get data from other geisters. So i believe i do something wrong, but i don`t know what.. or where to start sea...

Hi Anand

With the code in the attachment i get the following output:

Hello from Nios II!

targetadress 0x0

Error

Read chip ID: Read chip ID: Read chip ID: Read chip ID: Read chip ID: Data

Data

Data

so it seems he even do not set the target address 0x76.

When i use the oscilloscope, there is no communication on the pins.

Thank you!

Regards
