芯片的管脚上只占用四根线: MOSI: 主设备数据输出,从设备数据输入。 MISO: 从设备数据输出,主设备数据输入。 SCK: 时钟信号,由主设备发出。 CS(NSS): 从设备选择信号,由主设备控制。CS为低电平时选择从设备。 三线制SPI没有MISO,或者MISO和MOSI共线。 1.2 IIC与SPI区别 1. IIC只需要两根信号线,而标准的S...
1.在ESP8266里面有个API(system_get_chip_id())能够获得一个唯一ID号,请问在ESP32中是否也有类似的API呢? 2.如果没有相关API的话通过esp_efuse_mac_get_default()这个函数获取到的一个MAC地址是唯一所有芯片的MAC吗?如果不是,需要使用什么api来获得一个唯一ID呢? 3.在ESP-IDF4.0里面: esp_err_t esp_e...

ESP8266 NodeMCU has 2 LUA functions chip_id and flash_id which returns unique (I hope it's unique) identifier of processor chip and flash memory chip. Does ESP32 has similar capabilities? I've searched through esp-idf and did not find anything close enough to these functions ESP...
ESP32 chipID is now correct and unique. The previous releases' 32-bit wrong chipID is mainly the 24-bit Organizational Unique Identifier (OUI) plus 8 bits from the correct chipID. That's why ESP_getChipId() function can return duplicated values if the boards are from the same batch....

esp_chip_info(&chip_info);//获取芯片信息函数,只需将结构体地址传入 printf("Thisis%schipwith%dCPUcore(s),WiFi%s%s,", CONFIG_IDF_TARGET, chip_info.cores,/*芯片名称*/ (chip_info.features&CHIP_FEATURE_BT)?"/BT":"", (chip_info.features&CHIP_FEATURE_BLE)?"/BLE":""); ...
OTA(空中)更新是使用 Wi-Fi 连接而不是串行端口将固件加载到 ESP 模块的过程。 2.1、ESP32 的 OTA 升级有三种方式: Arduino IDE:主要用于软件开发阶段,实现不接线固件烧写 Web Browser:通过 Web 浏览器手动提供应用程序更新模块 HTTP Server:自动使用http服务器 - 针对产品应用 ...
