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...
ESP32-S2-WROOM下载后串口提示Invalid chip id. Expected 2 read 0. Bootloader for wrong chip?by DylanMingan » Wed Jul 01, 2020 9:11 am 板子是自制的,用的是ESP32-S2-WROOM模组 编译hello world例程并下载,控制台内容 esptool.py v3.0-dev Serial port COM3 Connecting... Detecting chip type.....
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?
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...
