I have interfaced an i2C sensor SHT40 with the DA14531MOD.
I am using it in the 7bit addressing mode.
I am trying to read the register address 0x89.
slave address (SHT40) is 0x44.
for which I am getting an ACK from the slave for I2C_WRITE command. but a NACK when I read the slave after transmitting 0x89.
Hi Sumo,Thank you for posting your question online.Could you kindly try to set a small delay between the write and read functionalities?Another approach would be to call your I2C function:
i2c_master_transmit_buffer_sync(®_addr, 1, &abort_code, I2C_F_WAIT_FOR_STOP);
i2c_master_receive_buffer_sync(&byte_received_SHT40, 6, &abort_code, I2C_F_WAIT_FOR_STOP);
