Hello! Trying to communicate between HPM6200EVK and QSFP transceiver using I2C controller on HPM6280. Both QSFP specifications (CMIS and SFF-8636) requires a special behavoiur of the I2C interface - we need to issue a first write (I2C address and Write bit) until we get an ACK for it. How cai I implement a such behaviour in HPM6280 (if it's theoretically possible)? |

Do you want to use I2C probe to find the slave device address? If so, you can use the i2c_master_read or i2c_master_write API; if the return value is status_success, the slave address exists |
