Re: 关于V1.5.0 rtos sdk的sntp sntp_set_system_time()函数

你好:
void sntp_set_system_time(sntp_time_t GMT_Time);这个接口不是给客户调用的,u32_t sntp_get_current_timestamp(void);
char* sntp_get_real_time(sntp_time_t t);这两个函数是获取本地时间的。

Re: question about macro "ICACHE_RODATA_ATTR"

hi
For ESP8266_RTOS SDK:
Functions are located in the IROM section by default and do not need to be attributed with ICACHE_FLASH_ATTR. Interrupt handlers can also run from IROM. Hence, if functions called frequently need to be run from IRAM, they should be attributed with IRAM_ATTR.
