HTTP 是协议层的,初始化时不用加载硬件驱动,所以它的仪式感就没那么强了。esp_http_client_config_t 结构体用于配置 HTTP 请求相关的信息。url 成员指定你要请求的URL,buffer_size 是esp处理传输数据的缓冲大小,不是你写代码时用的字节数组的大小。method 成员指定请求方式,如 GET、POST 等。
分区表以CSV的格式书写,用“#”注释;offset字段可以为空,程序会自动计算并填充该分区的偏移地址,但size字段一定要填写好 说明如下(抄自官网文档) Name字段可以是任何有意义的名称,但不能超过 16 个字符(之后的内容将被截断) Type 字段可以指定为app (0) 或data (1),也可以直接使用数字0-254(或者十六进制 0x...
