Farashin EK057
Abin da kuke Bukata
Don haɓaka aikace-aikace don ƙirar EK057 kuna buƙatar:
- 1 x EK057
- 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 daidaitawa akan Windows da macOS, da fatan za a koma zuwa Jagorar Shirye-shiryen ESP-IDF.
Haɗin Hardware
- Sayar da tsarin EK057 zuwa allon gwajin RF kamar yadda aka nuna a hoto 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. EK057 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 kan EK057, da fatan za a koma zuwa EK057 Datasheet.
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.
Shigar da Sakamako
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):

- 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.
Samu ESP-IDF
Don gina aikace-aikace don tsarin EK057, kuna buƙatar ɗakunan karatu na software wanda Espressif ya bayar a cikin ma'ajin ESP-IDF.
Don samun ESP-IDF, ƙirƙiri jagorar shigarwa (~/esp) don zazzage ESP-IDF zuwa kuma rufe ma'ajiyar tare da 'git clone':
- mkdir -p ~/esp
- cd ~/sa
- git clone --recursive https://github.com/espressif/esp-idf. git
Za a zazzage ESP-IDF zuwa ~/esp/esp-idf. Tuntuɓi Siffofin ESP-IDF don bayani game da wane nau'in ESP-IDF don amfani da shi a cikin yanayin da aka bayar.
Saita Kayan aiki
Baya ga ESP-IDF, kuna buƙatar shigar da kayan aikin da ESP-IDF ke amfani da su, kamar masu tarawa, debugger, fakitin Python, da sauransu. ESP-IDF tana ba da rubutun mai suna 'install.sh' don taimakawa saita kayan aikin. a tafi daya.

Saita Canjin Muhalli
Har yanzu ba a ƙara kayan aikin da aka shigar zuwa canjin yanayin PATH ba. Don yin amfani da kayan aikin daga layin umarni, dole ne a saita wasu masu canjin yanayi. ESP-IDF yana ba da wani rubutun 'export.sh' wanda ke yin hakan. A cikin tashar da za ku yi amfani da ESP-IDF, kunna: shigar .sh. $HOME/esp/esp-idf/export.sh
Yanzu komai yana shirye, zaku iya gina aikinku na farko akan tsarin EK057.
Ƙirƙiri Aikin Farko naku
