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...
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_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 ); ...
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_it函数的作用就是向指定从设备地址中的某一地址写入指定大小的数据。通过该函数,用户可以轻松发送各种数据类型,如uint8_t、uint16_t、uint32_t等。 三、使用方法 使用hal_i2c_mem_write_it函数前,需要先对I2C信号进行初始化。一般使用I2C HAL库,可以对I2C进行初始化。 以下是使用方法的示例...
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 ...
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 function.please let me know why HAL_I2C_Mem_Write_DMA() is didn't work.thank you.===//tes...
Description Some I2C devices require specific zero length read/write sequences which the HAL_I2C_IsDeviceReady() redirect interferes with. After Removing these redirects, it was confirmed that zer...
