In the main function, after the data has been stored to the memory location, the master will read the data from the same location.I2C_Write(EEPROMADDR, eepromwrite, 7); _delay_ms(1000); I2C_Read(EEPROMADDR, 0x0025, 2, eepromread, 5);...
Hi, I need to use I2C to write and read data and I have seen official demo codes. I found that codes will block to wait transfer complete. Blocking type codes may waste mcu resource. So I want to write and read data per 5ms by no waitting and mcu handles other tasks. How...
i2c_smbus_read_byte_data函数是用于从I2C从设备读取单个字节数据的函数。以下是针对你问题的详细解答: i2c_smbus_read_byte_data函数的作用: 该函数用于从指定的I2C从设备中读取一个字节的数据。它通常用于读取I2C设备上的特定寄存器值。 i2c_smbus_read_byte_data函数的返回值类型: 函数的返回类型是s32,即...
Data is read from the 3-axis accelerometer over I2C protocol. For a brief overview of the sensors, study the data sheet. The I2C protocol works with the main device initiating the start condition and sends a subordinate device address. Typicall...
We are working on a solution that involves i2C communication between the FPGA and FX3 development kit and are experiencing problems reading data from the FPGA registers. What we are trying to do is to read a single byte of data from a register (0x40) from the FPGA, using the F...
Solved: Hi, on a IMX6Q, MEAS MS5611 pressure sesor connected via I2C. Kernel configs: ``` CONFIG_IIO_SW_TRIGGER=y CONFIG_IIO_TRIGGERED_EVENT=y
data which minds the I2C interface of the master circuit and the slave circuit, it has the address counter which counts the address considerable number of the slave circuit, when the byte address which appoints the specified territory of the slave circuit is acquired, it makes the I2C ...

第二个参数是要读取的数据块的起始的寄存器的地址，也就是通过I2C总线从0x00寄存器开始连续读sizeof(struct xydata_t)个数据到y_data中。
also, regarding changing the I2C_BUFFER_LENGTH, there is a method, Code: Select all Wire.setBufferSize(255); but it fails to actually change the buffer size. 2) write a custom write/read/read where it reads half of the FIFO and then reads the next half. The problem I found with...
