Njengoko itekhnoloji ye-Intanethi iqhubeka nokukhula, umbono we-Intanethi weZinto (IoT) wazalwa. Ngokwenyani, i-IoT ithetha i-Intanethi apho izinto ziqhagamshelwe khona. Ngelixa i-Intanethi yasekuqaleni iphula imida yendawo kunye nexesha kwaye inciphisa umgama phakathi "komntu nomntu", i-IoT yenza "izinto" zibe ngumthathi-nxaxheba obalulekileyo, ukusondeza "abantu" kunye "nezinto" kunye. Kwixesha elizayo elibonakalayo, i-IoT imiselwe ukuba ibe yeyona nto iqhuba ishishini lolwazi.
Ke, yintoni i-Intanethi yeZinto?
Kunzima ukuchaza ngokuchanekileyo i-Intanethi yeZinto, njengoko intsingiselo yayo kunye nobubanzi buhlala buvela. Ngo-1995, uBill Gates waqala wavelisa umbono we-IoT kwincwadi yakhe ethi The Road Ahead. Ngamafutshane, i-IoT yenza ukuba izinto zitshintshiselane ngolwazi nge-Intanethi. Injongo yalo yokugqibela kukuseka "i-Intanethi yeYonke into". Oku kukutolikwa kwangaphambili kwe-IoT, kunye nefantasy yetekhnoloji yexesha elizayo. Kwiminyaka engamashumi amathathu kamva, kunye nophuhliso olukhawulezayo lwezoqoqosho kunye neteknoloji, ifantasy iyenzeka.

Umzobo 4.15. File Ubume bolawulo lweprojekthi yokuqhwanyaza

kufuneka zibandakanywe njengoko kuchaziwe kwicandelo 4.3.2. Ulawulo oluphambili lusetyenziswa ikakhulu ukugcina ukuphunyezwa kwe app_main() umsebenzi, oyindawo yokungena kwinkqubo yomsebenzisi.Iprojekthi yokuqhwanyaza ayibandakanyi uluhlu lwamacandelo, kuba loampLe ifuna kuphela ukusebenzisa amacandelo eza ne-ESP-IDF kwaye ayifuni malungu ongezelelweyo. I-CMakeLists.txt ebandakanyiweyo kwiprojekthi yokuqhwanyaza isetyenziselwa ukukhokela inkqubo yoqulunqo, ngelixa i-Kconfig.projbuild isetyenziselwa ukongeza izinto zoqwalaselo zale ex.ample nkqubo kwi menuconfig. Okunye okungeyomfuneko files aziyi kuchaphazela ukudityaniswa kwekhowudi, ngoko ke aziyi kuxoxwa apha. Intshayelelo eneenkcukacha yeprojekthi yokuqhwanyaza files imi ngolu hlobo lulandelayo.

1. /*blink.c ibandakanya okubhalwe ngasentla kwekhasi kulandelayo files*/

2. #zibandakanya

//Isihloko selayibrari esisemgangathweni C file

3. #bandakanya "freertos/freeRTOS.h" //FreeRTOS intloko ephambili file

4. #bandakanya "freertos/task.h"

//FreeRTOS Task header file

5. #bandakanya "sdkconfig.h"

//Uqwalaselo olungasentla file yenziwe yi kconfig

6. #bandakanya "umqhubi/gpio.h"

//GPIO iheader yomqhubi file

Umthombo file blink.c iqulathe uluhlu lweheader files ihambelana nesibhengezo somsebenzi-

tions. I-ESP-IDF ngokubanzi ilandela ulandelelwano lokuquka iheader yethala leencwadi eqhelekileyo files, FreeR-

Okubhalwe ngasentla kwe-TOS files, iheda yomqhubi files, esinye isihloko secandelo files, kunye nesihloko seprojekthi files.

Ulandelelwano lwesihloko files zibandakanyiwe zinokuchaphazela umphumo wokugqibela woqulunqo, ngoko zama uku

landela imithetho engagqibekanga. Kufuneka kuqatshelwe ukuba i-sdkconfig.h yenziwe ngokuzenzekelayo

nge kconfig kwaye ingaqwalaselwa kuphela ngomyalelo idf.py menuconfig.

Ukuguqulwa okuthe ngqo kwesi sihloko file iya kubhalwa ngaphezulu.

1. /*Ungakhetha i-GPIO ehambelana ne-LED kwi-idf.py menuconfig, kunye nesiphumo sokuguqulwa kwe-menuconfig kukuba ixabiso le-CONFIG_BLINK

_GPIO iza kutshintshwa. Ungaguqula ngokuthe ngqo inkcazo enkulu

apha, kwaye utshintshe CONFIG_BLINK_GPIO kwixabiso elimiselweyo.*/ 2. #define BLINK_GPIO CONFIG_BLINK_GPIO

3. i-app engasebenziyo_engundoqo(ingenanto)

4. {

/* Qwalasela i-IO njengomsebenzi ongagqibekanga we-GPIO, yenza imowudi yokutsalela phezulu, kunye

/*Seta iGPIO kwimowudi yemveliso*/ gpio_set_direction(BLINK_GPIO, GPIO_MODE_OUTPUT); ngelixa(1) {
/*Shicilela umbhalo*/ printf(“Ukucima i-LEDn”); /*Cima i-LED (imveliso ephantsi kwinqanaba)*/ gpio_set_level(BLINK_GPIO, 0); /*Libazisa (1000 ms)*/ vTaskDelay(1000 / portTICK_PERIOD_MS); printf(“Ukuvula i-LEDn”); /*Vula i-LED (imveliso ephezulu)*/ gpio_set_level(BLINK_GPIO, 1); vTaskDelay(1000 / portTICK_PERIOD_MS); }

I-app_main () umsebenzi kwi-Blink example nkqubo isebenza njengendawo yokungena yeenkqubo zabasebenzisi. Ngumsebenzi olula ongena parameters kwaye akukho xabiso lembuyekezo. Lo msebenzi ubizwa emva kokuba inkqubo igqibile ukuqaliswa, equka imisebenzi efana nokuqalisa i-port ye-serial port, ukuqwalasela isiseko esisodwa/ezimbini, kunye nokuqwalasela umlindi.

I-app_main () umsebenzi uqhuba kumxholo womsebenzi obizwa ngokuba ngundoqo. Ubungakanani besitaki kunye nokubaluleka kwalo msebenzi kunokuhlengahlengiswa kwi-menuconfig Componentconfig Common ESP enxulumene.

Kwimisebenzi elula efana nokuqhwanyaza kwe-LED, yonke ikhowudi efunekayo inokuphunyezwa ngokuthe ngqo kwi-app_main () umsebenzi. Oku kubandakanya ukuqala kwe-GPIO ehambelana ne-LED kunye nokusebenzisa i-loop (1) iluphu ukuguqula nokuvala i-LED. Kungenjalo, ungasebenzisa iFreeRTOS API ukwenza umsebenzi omtsha ophethe ukuqhwanyaza kwe-LED. Nje ukuba umsebenzi omtsha wenziwe ngempumelelo, unokuphuma kwi-app_main () umsebenzi.

Umxholo we-main/CMakeLists.txt file, ekhokela inkqubo yokuhlanganiswa kwecandelo eliphambili, ngolu hlobo lulandelayo:

1. idf_component_register(SRCS “blink.c” INCLUDE_DIRS “.” )

Phakathi kwazo, i-main/CMakeLists.txt ibiza kuphela umsebenzi wenkqubo yokudibanisa enye, oko kukuthi idf_component_register. Ngokufana ne-CMakeLists.txt kuninzi lwamanye amacandelo, i-blink.c yongezwa kwi-SRCS, kunye nomthombo fileidityaniswe kwi-SRCS iya kuqulunqwa. Ngaxeshanye, ".", emele indlela apho iCMakeLists.txt ikhona, kufuneka yongezwe kwi INCLUDE_DIRS njengokukhangela abalawuli beheader. files. Umxholo we-CMakeLists.txt umi ngolu hlobo lulandelayo:
1. # Cacisa i-v3.5 njengolona guqulelo ludala lweCMake oluxhaswa yiprojekthi yangoku 2. #Iinguqulelo ezingaphantsi kwe-v3.5 kufuneka ziphuculwe phambi kokuba kuqhubeke ukuhlanganiswa 3. cmake_minimum_required(VERSION 3.5) 4. #Bandakanya uqwalaselo lweCMake olungagqibekanga lwe-ESP -I-IDF yokuhlanganisa inkqubo
