Hal_I2C_Mem_Read. Again, consider an i 2 c sensor in which measurements are stored in a specific register on the slave and the master must read data from that register. My code is reading the data from slave via i2c bus using hal_i2c_mem_read function.
My code is reading the data from slave via i2c bus using hal_i2c_mem_read function. So i implemented this function, which is also called every cycle the control loop runs. Web using hal_i2c_mem_write and hal_i2c_mem_read. The frequency of the control loop increased to 7khz now, but that's still not enough for my application. Web in some cases hal_i2c_mem_read will finish reading given number of bytes from i2c slave, but will not nak the last byte. However, i'm having trouble with the memaddsize parameter. Web hal_i2c_mem_read() this api function is used to request data from a slave device from a specific memory address. Web hardware overview of i2c in stm32. #define reg_chip_id 0x00 hal_i2c_mem_read(&i2chandle, i2c_address, reg_chip_id, i2c_memadd_size_8bit, &arxbuffer, 1, 10000); Hi, i am trying to establish i2c communication between my stm32 nucleo 411re and this em7180 sensor fusion coprocessor using the hal_i2c_mem_write ()/read () functions.
It supports the standard mode (sm, up to. My code is reading the data from slave via i2c bus using hal_i2c_mem_read function. These are the top rated real world c++ (cpp) examples of hal_i2c_mem_read extracted from open source projects. Web until i added reading the chip like every 100ms. Web hal_i2c_mem_read() this api function is used to request data from a slave device from a specific memory address. Web hal_i2c_mem_read (i2c_handletypedef * hi2c, uint16_t devaddress, uint16_t memaddress, uint16_t memaddsize, uint8_t * pdata, uint16_t size, uint32_t timeout); #define reg_chip_id 0x00 hal_i2c_mem_read(&i2chandle, i2c_address, reg_chip_id, i2c_memadd_size_8bit, &arxbuffer, 1, 10000); Web what you want to do is to read a register, so don't use hal_i2c_master_receive or hal_i2c_master_transmit, but hal_i2c_mem_read or hal_i2c_mem_write, like this: Again, consider an i 2 c sensor in which measurements are stored in a specific register on the slave and the master must read data from that register. However, i'm having trouble with the memaddsize parameter. You can rate examples to help us improve the quality of examples.
