What is the function corresponding to nrf_drv_twi_tx SPI communication?

[y001]

Hello

I used to do TWI communication until now, but it was decided to do sensor reading with SPI communication by changing the sensor.

So that's a question,

What is the function corresponding to nrf_drv_twi_tx SPI communication?

What we want to do by knowing this command is to write a value to the sensor address. This will make settings.

Thank you.

Have you looked at the documentation?

Have you looked at the examples?

Remember that there's a number of fundamental difference between SPI and I2C:

• SPI is full-duplex
• SPI purely defines the electrical level - it has no higher protocol for addressing, ACKing, etc

This was what I wanted to do
nrf_drv_spi_transfer (& spi, reg_addr, sizeof (reg_addr), NULL, 0);
You should make NULL the reception place
