In this we tried i2c based eeprom device read and write. Data write we followed: void data_write(uint8_t Byte_address, uint8_t value){ I2C_MasterStart(((I2C_Type *)(I2C2_BASE)), 0x50U, kI2C_Write); I2C_MasterWriteBlocking(((I2C_Type *)(I2C2_BASE)), &Byte_address, 1, k...
要先擦除,再写入。
i2cParams.transferMode = I2C_MODE_BLOCKING; I2C = I2C_open (Board_I2C_TMP、&i2cParams); 如果(!i2c){ log_error0 ("初始化 I2C\n 时出错"); while (1); } 否则{ log_info0 ("I2C initialized!\n"); } //初始化 PPG I2C_writeRegister (PPGaddr、0x01、0x20);//启用 ...
I read that section, but I thought waiting for acknowledgement was part of the HAL Blocking I2C functions with the timeout. If the HAL_I2C_Mem_Write function wasn't getting an acknowledgement back within the timeout period wouldn't it return a HAL_ERROR of some kind...

Since the "while(I2C_BUSY == I2C_Close()); " creates an automatic blocking loop, how would you recommend changing this in the i2c_master.c file? Once I implement the change above, what would be the best practice to check the status of the I2C for failures or problems? This section ...
