提交stm32 bsp drv_pwm.c里面的一个小建议 (#6517) 
在使用stm32的pwm驱动时，发现其初始化channel的时候是根据device->channel这个值去初始化的，device->channel这个值是在pwm_configh.h里面定义设置的，又根据rtt的pwm例程，和常规习惯，应该大多数人会更喜欢设置channel=1/2/3/4，而不是在pwm_configh.h中将channel设置为TIM_CHANNEL_1/2/3/4，因此建议drv_pwm.c做出PR中的修改。

在实际开发中，因pwm_configh.h的示例均是.channel=0，又没有做出解释说明要让.channel=TIM_CHANNEL_1/2/3/4的值，容易误操作导致没有成功输出PWM，这是我在实际开发中遇到的现实问题，因而提出此建议。

[rtduino] 对接STM32F412 NUCLEO (#6461) 2022-09-25 22:38:35 -04:00
YangZhongQing 1c2d05d545 RTC STM32F1 Enable PWR and BKP clocks in the same time 
bsp\stm32\libraries\HAL_Drivers\drv_rtc.c在STM32F10x上有一个“RTC首次上电时BKP时钟没使能”的问题。

STM32F10x要求：
写RTC Domain and RTC registers之前需要__HAL_RCC_BKP_CLK_ENABLE（详见：stm32f1xx_hal_rtc.c里面的##### Backup Domain Access #####）

问题分析：
1、RTC首次上电时：由于HAL_RTC_Init初始化之前没有使能BKP时钟，所以对RTC registers的初始化无效。
2、然后用date命令设置时间，调用到set_rtc_time_stamp也没有__HAL_RCC_BKP_CLK_ENABLE，所以HAL_RTCEx_BKUPWrite写的值无法真正永存于BKP，重启后就丢失。
最终导致：对于RTC首次上电的情况，每次重启后RTC_BKP_DR1里的值都不是BKUP_REG_DATA，导致永远无法调用到rt_rtc_f1_bkp_update()去使能BKP时钟。

解决办法：
参考STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\RTC\Calendar\main.c里面的RTC_Configuration()同时打开RCC_APB1Periph_PWR和RCC_APB1Periph_BKP

[ulog][rtc][time][bug] solve the interference when enable the ulog timestamp (#5687) 
* [ulog] 解决ulog开启时间戳后与libc time以及rtc驱动相关函数干涉的问题
* ulog：当发生递归输出时，后续递归想要输出的内容可能会因为防范递归的判断而无法输出
因此修改输出规则，在发生递归时，采用简单的，无格式的方式直接输出。这样既保证不会发生递归输出，也可以保证递归输出的部分可以正常输出。
* [ulog] size_t->rt_size_t NULL->RT_NULL
