HAL_I2C_Mem_Write()函数位于stm32fxx_hal_i2c.c文件的2432行,源代码对该函数的解释如下图 HAL_StatusTypeDef HAL_I2C_Mem_Write(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddSize, uint8_t *pData, uint16_t Size, uint32_t Timeout ); 该函数是通过阻塞...
HAL_I2C_Mem_Write 是STM32 HAL库中用于向I2C设备的指定内存地址写入数据的函数。关于该函数的返回值,以下是详细的解释: 返回值类型 HAL_I2C_Mem_Write 函数的返回类型是 HAL_StatusTypeDef。这是一个枚举类型,用于表示函数执行的结果。 返回值含义 HAL_OK:函数执行成功,数据已成功写入I2C设备的指定内存地址。
HAL_StatusTypeDef HAL_I2C_Mem_Write(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddSize, uint8_t *pData, uint16_t Size, uint32_t Timeout) 参数说明如下: * hi2c:I2C句柄 * DevAddress:I2C设备地址 * MemAddress:要写入的内存地址 * MemAddSize:内存地址...
Hi, I am working on a project using the STM32H730 with the M24C64 I2C EEPROM chip. In my project I am using the HAL_I2C_Mem_Write functions to load
HAL_I2C_Mem_Write_DMA 返回 HAL_OK。当我走进它时，这是它返回前的状态：请注意，XferCount 以 ...
下面就来对hal_i2c_mem_write_it函数第一字节进行详细解析。 一、函数定义 hal_i2c_mem_write_it函数定义如下: HAL_StatusTypeDef hal_i2c_mem_write_it(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddSize, uint8_t *pData, uint16_t Size) 其中,参数含义如下...
I'm trying to I2C communication between STM32F4(master) and IC(slave, 7bit address).I tested to two functions for I2C communication.HAL_I2C_Mem_Write is OK, but HAL_I2C_Mem_Write_DMA is fail.Test condition and setting parameters are same only except the ...
and using i2c.mem_read(…) is that send;recv puts the I2C bus into the 'stop' state between the end of the write and the beginning of the read command, while mem_read puts the 'repeated start' state on the bus instead. One of the components on my board is fine with this, while...
