bq24195设置寄存器问题

我在项目中用到了BQ24195，通过STM32单片机的I2C读写寄存器，现在发现我可以正常的读寄存器的值，但我如果设置寄存器时，设置相关寄存器后读取的话显示是0，过一段时间后显示为默认值，无论CE脚设置是高电平或低电平。

亲；你是如何设置寄存器的？

你好！

我的部分代码如下：

CE_POWER = 0;
delay_ms(2000);

slave_addr = 0x6B;reg_addr = 0x1;data_addr = 0x2b;

i2c_write_sreg(slave_addr,reg_addr,data_addr);
delay_ms(500);

reg_data = i2c_read_sreg(slave_addr, reg_addr) ;printf("0x%02x ",reg_data);
delay_ms(500);

unsigned char i2c_read_sreg(unsigned char slave_addr, unsigned char reg_addr)
{
int i;
unsigned char t;
unsigned char reg_data;
i2c_start(); 
t = (slave_addr << 1) | 0; 
i2c_write_byte(t);
i2c_write_byte(reg_addr);

i2c_start();
t = (slave_addr << 1) | 1; 
i2c_write_byte(t);
//i2c_write_byte(reg_addr);
reg_data = i2c_nread_byte();
i2c_stop();
return reg_data;
}

void i2c_write_sreg (unsigned char slave_addr, unsigned char reg_addr, unsigned char reg_data) 

{
int i;
unsigned char t;
i2c_start(); 
t = (slave_addr << 1) | 0;
i2c_write_byte(t);
i2c_write_byte(reg_addr);
//i2c_write_byte(slave_addr);
i2c_write_byte(reg_data);
i2c_stop();
return;
}

看你的程序步骤没错啊，现在调通了吗？我也遇到这个问题，读写不了寄存器，能发你的例程我看看吗？274344073@qq.com
