Pulse Encoder读出来的值出现了溢出情况怎么办

我在RT-THREAD Studio中导入了github上的rt-thread最新pulse encoder的驱动，在调试过程中，发现读出来的编码器的值明明很小，却时常出现溢出值

我的读取周期为20ms读取一次，出现溢出的情况越来越严重，读取周期短一点则出现的概率不高

while(1)
{
rt_thread_mdelay(CONTROL_TICK); //挂起20ms
rt_enter_critical();
kinetic_calc(x_speed, y_speed, z_speed, target_encoder); //获取电机目标
#if DEBUG_PID
rt_device_read(encoder[0], 0, &encoder_value, 1); /BUG:这里读值的时候会溢出/
//rt_kprintf("Read value:%d \n",encoder_value);
//outpwm[m_n] += IncPID(0,targetEncoder_test, &motor_pid[m_n]);
rt_device_control(encoder[0], PULSE_ENCODER_CMD_CLEAR_COUNT, RT_NULL);
rt_kprintf("Read value:%d \n",encoder_value);
#else
outpwm[0] += IncPID(GET_CURRENT_ENCODER(0), v2encoder(target_encoder[0]), &motor_pid[0]);
outpwm[1] += IncPID(GET_CURRENT_ENCODER(1), v2encoder(target_encoder[1]), &motor_pid[1]);
outpwm[2] += IncPID(GET_CURRENT_ENCODER(2), v2encoder(target_encoder[2]), &motor_pid[2]);
outpwm[3] += IncPID(GET_CURRENT_ENCODER(3), v2encoder(target_encoder[3]), &motor_pid[3]);
#endif
//输出PWM
rt_exit_critical();
}
