I2C write TWI without address

[Wenne]

Hallo I'm writing Data to the I2C port.

I'm using the nrf_drv_twi_tx function. It works well. 

But I want to write bytes to the I2C without Adress. - i want to write just a byte - is there another TWI function I missed ?

Tahnk you very much.

best regards Wenne

Hi Wenne

Do you mean you want to write multiple bytes after the address, or you want to write data without an address at all?

The TWI specification requires an address to be sent after each start condition, and our hardware is designed around this principle, so we don't really have a way of sending bytes without first sending an address. 

Best regards

i just want to write 1 byte.

if this byte is an address or data is my responsibility

( I want to drive a oled display with i2C interface and U8g2 api. )
