除非禁用CONFIG_ESP_SYSTEM_ALLOW_RTC_FAST_MEM_AS_HEAP 选项,否则剩余的 RTC FAST memory 会被添加到堆中。该部分内存可以和 DRAM(数据 RAM) 互换使用,但是访问速度稍慢一点。 使用方式: #include <esp_attr.h> RTC_IRAM_ATTR uint32_t rtc_iram_data; RTC_FAST_ATTR uint32_t rtc_fast_data; 1. 2...
ESP32有快速和慢速两片RTC内存区域,各8K大小。对于我们用户引用来说用来存储数据主要用到慢速的RTC内存。 使用RTC_DATA_ATTR标记的数据将被放置在RTC内存中,比如RTC_DATA_ATTR int data = 0;,在程序中可以通过变量名直接访问。 使用示例 使用下面代码进行测试: RTC_DATA_ATTR int bootCount = 0; //将变量存放...
