  固定4步来一个中断，停止走路时再来一个中断，灵敏度是10寄存器

      bResult = gsensor_i2c_write_byte(0x10, 0x2a);
bResult =  gsensor_i2c_write_byte(0x0f, 0x04);

bResult = gsensor_i2c_write_byte(0x12, 0x8f);
bResult = gsensor_i2c_write_byte(0x13, 0x10);
bResult = gsensor_i2c_write_byte(0x14, 0x14);

bResult = gsensor_i2c_write_byte(0x20, 0x00); // 低电平或者下降沿触发
//bResult = gsensor_i2c_write_byte(0x20, 0x05);// 高电平或者上升沿触发

bResult = gsensor_i2c_write_byte(0x11, 0x80);
