This library enables slaves to initiate a data exchange by interrupting the master which then starts the I2C transactions. There is a timing issue in that the I2C master requires that the slave be ready before it initiates a transfer. jersey mike's santee ca menuWebb16 juni 2024 · while (HAL_I2C_Master_Transmit (&hi2c1, (uint16_t)SLAVE_ADDRESS, (uint8_t*)d8_on_tx, D8_ON_TX_SIZE, 20)!=HAL_OK) { if (HAL_I2C_GetError (&hi2c1) != HAL_I2C_ERROR_AF) { Error_Handler (); } } This way, you will wait until the transmission completes and if there is an acknowledgement failure you can act on it. lam dong ho de ban lop 3
