TWI: prevent repeated start between non stop transfer

[Aurabindo]

Hi,

I am debugging an SSD1306 OLED library, and in the datasheet, it does not explicitly mention support for repeated start bits. But using the nrf_drv_ API's with NRF_DRV_TWI_FLAG_TX_NO_STOP flag set, the successive nrf_drv_twi_tx or nrf_drv_twi_xfer function starts sending data with a start condition.

As shown by the logic analyzer, the Green dot is a start ad red dot is a stop. I dont not want the last green dot to the right. Is this possible using the nrf_drv_twi_ API ?

Hi Aurabindo, I am getting the same problem with the SSD1306. Splitting up the data to smaller chunks did not work for me. I think its caused by the extra start bit everything a new chunk begins. How did you solve the problem? Thank you!
