[yoyou]

Hello,

NCS1.9.1,  Windows10 X64,nRF5340-DK,

NCS1.9.1, i2c_api can't bulid - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

i'm sorry,i clicked [verify answer] by mistake.

it can build runing,but i2c_get_config() fail.return -88.

 

nRF5340-DK  does not connect anything.

test  default codes from NCS1.9.1,

that is [\v1.9.1\zephyr\tests\drivers\i2c\i2c_api],

Do I have to link to peripheral I2C devices?

 

thanks

Best Regards

Hi,

thank you very much,

though it still can't get i2c_get_config;

but i learned some information from it.

Hi,

yes,it still can't get i2c_get_config.

nRF5340-DK  does not connect anything.

Do I have to link my I2C device to get it?

or,can operate read and write without i2c_get_config.

  

thanks

Hi,

if i skip  get i2c_get_config.

and connect a device,write failed.

  

it seems to be a great need for an I2C sample code.

  

thanks

Hi,

i2c_get_config is normally used the get the configuration and does not necessarily pertain to reading and writing.
