Re: os_delay_us 和vTaskDelay的区别是什么呢?

os_delay_us 不会主动让出 CPU,且是 us 级的;
vTaskDelay 会主动让出 CPU,且最少时间片大很多

Re: ESP8266 2MB + OTA

Did you select the 16Mbit on your flash download tool while downing?
And you should note that the system parameter area is always the last 4 or 5 sectors of your flash (16Mbit), you should not save any user data there.

Re: PICO 芯片的手工焊接?

高级点的芯片都这样吧,焊盘在下面,如果要手工焊接的话,需要使用热风枪吹。

Re: 乐鑫官方RTOS整合阿里云物联网套件,运行REMOTE_OTA_TASK出错。

掉电重新上电,还能正常运行吗?是不是 OTA 误操作 flash,把当前程序擦写了。
