HAL_StatusTypeDef res = HAL_I2C_Mem_Read(hi2c, DevAddress, mem_base_address + offset, I2C_MEMADD_SIZE_16BIT, &data, 1, 100); HAL_Delay(1); return data; } /** * @brief Writes a block of data to i2c_eeprom memory */ void persistent_memory_i2c_eeprom::...
MCU复位的情况下HAL_I2C_Mem_Read函数有几率返回错误 说到MCU的复位肯定是不陌生了,但究竟其怎么工作的,设计其目的和作用是什么呢?其实我们程序最初的加载就与复位有关,比如一上电,MCU就自动执行我们设计的程序,复位有很多种,比如异常复位(程序跑飞阿,电源不稳定阿,看门狗喂狗超时阿),但不管哪种复位,其做的大多...
(HAL_I2C_Mem_Read) 是否 100% 正确,因为我不确定“I2C_WaitOnFlagUntilTimeout(hi2c, I2C_FLAG_...
我看代码 有两种方式 一种是软件模拟IIC时序 一种是库函数IIC 跟你说的是一回事儿吗?
