Farawa akan ESP32MINI1
2.1 Abin da kuke Bukata
Don haɓaka aikace-aikace na ESP32-MINI-1 module kuna buƙatar:
- 1 x ESP32-MINI-1 module
- 1 x Espressif RF kwamitin gwaji
- 1 x USB-to-Serial allon
- 1 x Kebul na Micro-USB
- 1 x PC mai sarrafa Linux
A cikin wannan jagorar mai amfani, muna ɗaukar tsarin aiki na Linux azaman example. Don ƙarin bayani game da sanyi akan Windows da macOS, da fatan za a koma zuwa Jagorar Shirye-shiryen ESP-IDF.
2.2 Haɗin Hardware
- Sayar da tsarin ESP32-MINI-1 zuwa kwamitin gwaji na RF kamar yadda aka nuna a Hoto 2-1.
- Haɗa allon gwajin RF zuwa allon USB-zuwa-Serial ta TXD, RXD, da GND.
- Haɗa allon USB-zuwa-Serial zuwa PC.
- Haɗa allon gwajin RF zuwa PC ko adaftar wuta don ba da damar samar da wutar lantarki 5 V, ta kebul na Micro-USB.
- Yayin zazzagewa, haɗa IO0 zuwa GND ta hanyar tsalle. Sannan, kunna “ON” allon gwaji.
- Zazzage firmware cikin filasha. Don cikakkun bayanai, duba sassan da ke ƙasa.
- Bayan zazzagewa, cire jumper akan IO0 da GND.
- Ƙaddamar da allon gwajin RF kuma. ESP32-MINI-1 zai canza zuwa yanayin aiki. Guntu zai karanta shirye-shirye daga walƙiya lokacin farawa.
Lura:
IO0 yana da ma'ana cikin ciki high. Idan an saita IO0 don cirewa, an zaɓi yanayin Boot. Idan wannan fil ɗin yana jan ƙasa ko hagu yana iyo, an zaɓi yanayin zazzagewa. Don ƙarin bayani akan ESP32-MINI-1, da fatan za a koma zuwa ESP32-MINI-1 Datasheet.
2.3 Kafa Muhallin Ci Gaba
Tsarin Ci gaban Espressif IoT (ESP-IDF a takaice) tsari ne don haɓaka aikace-aikace dangane da Espressif ESP32. Masu amfani za su iya haɓaka aikace-aikace tare da ESP32 a cikin Windows/Linux/macOS dangane da ESP-IDF. Anan muna ɗaukar tsarin aiki na Linux azaman example.
2.3.1 Shigar da Abubuwan da ake bukata
Don haɗa tare da ESP-IDF kuna buƙatar samun fakiti masu zuwa:
- CentOS 7:
sudo yum shigar git wget flex bison gperf python cmake ninja -build ccache dfu-util - Ubuntu da Debian (umarni ɗaya ya kasu kashi biyu):
sudo dace-samun shigar git wget flex bison gperf python-pip python-setuptools cmake ninja -build-cache libffi -dev libssl -dev dfu-util - Arch:
sudo Pacman -S --bukata gcc git yi flex bison gperf python-pip cmake ninja ccache dfu-util
Lura: - Wannan jagorar tana amfani da directory ~/esp akan Linux azaman babban fayil ɗin shigarwa don ESP-IDF.
- Ka tuna cewa ESP-IDF baya goyan bayan sarari a cikin hanyoyi.
2.3.2 Sami EPIDF
Don gina aikace-aikacen ESP32-MINI-1, kuna buƙatar ɗakunan karatu na software wanda Espressif ya bayar a ciki. ESP-IDF ma'ajin.
Don samun ESP-IDF, ƙirƙiri jagorar shigarwa (~/esp) don zazzage ESP-IDF zuwa kuma rufe ma'ajiyar tare da 'git clone':

Za a sauke ESP-IDF zuwa ~/esp/esp-idf. Shawara Sigar ESP-IDF don bayani game da wane nau'in ESP-IDF don amfani da shi a cikin wani yanayi da aka bayar.
2.3.3 Saita Kayan aiki
Baya ga ESP-IDF, kuna buƙatar shigar da kayan aikin da ESP-IDF ke amfani da su, kamar mai tarawa, mai gyara kurakurai,
Fakitin Python, da sauransu. ESP-IDF yana ba da rubutun mai suna 'install.sh' don taimakawa saita kayan aikin a tafi ɗaya.

Akwai kewayon exampda ayyukan a cikin exampLes directory a cikin ESP-IDF. Kuna iya kwafi kowane aiki kamar yadda aka gabatar a sama kuma ku gudanar da shi. Hakanan yana yiwuwa a gina examples in-place, ba tare da kwafi su farko ba.
2.4.2 Haɗa na'urar ku
Yanzu haɗa na'urar ESP32-MINI-1 ɗin ku zuwa kwamfutar kuma duba ƙarƙashin tashar tashar tashar jiragen ruwa na ganuwa. Serial ports a Linux suna farawa da '/ dev/tty' a cikin sunayensu. Gudun umarni a ƙasa sau biyu, na farko tare da cire allon, sannan tare da toshewa. Tashar jiragen ruwa da ke bayyana a karo na biyu shine wanda kuke buƙata:
