char ee_24clxx_writebytes(uint16_t write_addr, char* pwrite_buff, uint16_t writebytes)
函数内write_len,page_offset两个变量应该同writebytes一样为uint16而不是uint8
/* 读写指令 /
#define READ_EN 0x40 / 读使能 /
#define CONTINUE_READ 0x20 / 连续读 */
参见AD7793数据手册连续读使能位应该为CR2,也就是第三位,因此应该修正为0x02。
int8_t ee_24clxx_init(struct i2c_dev_device *i2c_bus)
{
if (NULL == i2c_bus)
{
return -1;
}
ee_i2c_dev = i2c_bus;
return 0;
}
你可以打印试试:printf("%d \r\n",sizeof(-1));
