有没有办法在ARM9上生成随机数？

嗨，Markus，
我们没有一个随机发生器上的FX3硅。唯一的硬件选项是设置一个GPIO定时器，具有低周期（周期=要产生的值的范围），并对其进行采样以获得随机数。
CYU3PGPIOSETFIXCONFIGIG函数可用于设置定时器：
CYU3PGPIOFieldCopyIt t GPIOCONF= {
CyFoE，CyFalse，CyFalse，CyFalse，
CYU-U3PGPIOOYMODEMIDEA静态，/GPIO本身不受影响，我们只需使用定时器。*/
CyuU3pGPooIoNoIIn，/*没有与此定时器关联的中断。*/
CYU-U3PGPIOIOTIMERYHYFRQ，/*在GPIOIIT中选择的高时钟频率下运行GPIO。*/
0，/*启动定时器在0。*/
RealthyMax，/*将周期设置为要生成的数字的范围。*/
0，门槛是不在乎的。*/
}；
CYU3PGPIOSET-FixFixFigg（0，GPIOCONF）；
然后可以使用CYU3PGPIOXION SAMPrPulOW函数获得当前计时器值作为随机数。
请注意，需要将随机数MAX设置为低值以获得良好的熵。
谢谢，
Sai Krishna。

  Hi Markus,
     
    We do not have a random generator on the FX3 silicon. The only hardware option is to set up a GPIO timer with a low period (period = range of values to be generated) and sample it to get the random number.
     
    The CyU3PGpioSetComplexConfig function can be used as follows to set up the timer:
     
    CyU3PGpioComplexConfig_t gpioConf = {
                    CyFalse, CyFalse, CyFalse, CyFalse,
                    CY_U3P_GPIO_MODE_STATIC,                 /* The GPIO itself is not to be affected, we just use the timer. */
                    CY_U3P_GPIO_NO_INTR,                            /* No interrupts associated with this timer. */
                    CY_U3P_GPIO_TIMER_HIGH_FREQ,       /* Run the GPIO at the high clock frequency selected at GpioInit. */
                    0,                                                                            /* Start timer at 0. */
                    RANDOM_MAX,                                              /* Set the period to the range of the numbers to be generated. */
                    0                                                                              /* The threshold is don't care. */
    };
    CyU3PGpioSetComplexConfig (0, &gpioConf);
     
    The CyU3PGpioComplexSampleNow function can then be used to get the current timer value to serve as a random number.
     
    Please note that the RANDOM_MAX needs to be set to a low value to be able to get good entropy.
     
    Thanks,
    Sai Krishna.

我想你也可以使用ApCYU3pGETTIME获取系统时间。我做了一些运算，得到一个随机数。

   I think you can also use the api CyU3PGetTime to get the system time. I do some operation on it to get a random number .

你好
谁能告诉我如何将CYU3PGPIO复杂采样的时钟号转换为时间

  hi
    who  can tell me how to convert the number of tick from CyU3PGpioComplexSampleNow  to time
