Tīmatahia te EK057
He aha e hiahia ana koe
Hei whakawhanake i nga tono mo te waahanga EK057 ka hiahia koe:
- 1 x EK057 kōwae
- 1 x Espressif RF papa whakamatautau
- 1 x papa USB-ki-Raarangi
- 1 x Micro-USB taura
- 1 x PC whakahaere Linux
I roto i tenei aratohu kaiwhakamahi, ka tangohia e matou te punaha whakahaere Linux hei tauiraample. Mo etahi atu korero mo te whirihoranga i runga i te Matapihi me te macOS, tirohia koa te Aratohu Papatono ESP-IDF.
Hononga taputapu
- Whakauruhia te kōwae EK057 ki te papa whakamatautau RF pera i te Whakaaturanga 1.
- Honoa te papa whakamatautau RF ki te papa USB-ki-Serial ma te TXD, RXD, me te GND.
- Honoa te papa USB-ki-Serial ki te PC.
- Honoa te papa whakamatautau RF ki te PC, ki te urutau hiko ranei kia taea ai te tuku hiko 5 V, ma te taura Micro-USB.
- I te wa e tango ana, honoa te IO0 ki te GND ma te peke. Na, hurihia te "ON" te papa whakamatautau.
- Tikiake firmware ki te flash. Mo nga taipitopito, tirohia nga waahanga kei raro nei.
- I muri i te tikiake, tangohia te pekepeke i runga i te IO0 me te GND.
- Whakanuia ano te papa whakamatautau RF. Ka huri a EK057 ki te aratau mahi. Ka panuihia e te maramara nga papatono mai i te flash i te arawhitinga.
Tuhipoka:
Ko te IO0 he arorau o roto. Mena kua whakaritea a IO0 ki te kumea-ake, ka tohua te aratau Whakaara. Mena kei te kumea-iho tenei titi, kei te maanu ranei, ka tohua te aratau Tikiake. Mo etahi atu korero mo EK057, tirohia te Pepa Raraunga EK057.
Whakaritehia te Taiao Whanaketanga
Ko te Anga Whakawhanake IoT Espressif (ESP-IDF mo te poto) he anga mo te whakawhanake i nga tono i runga i te Espressif ESP32. Ka taea e nga kaiwhakamahi te hanga tono me te ESP32 ki Windows/Linux/macOS i runga i te ESP-IDF. I konei ka tangohia e matou te punaha whakahaere Linux hei tauiraample.
Whakaritea nga Whakaritenga
Hei whakahiato me te ESP-IDF me whiwhi koe i nga kohinga e whai ake nei:
- CentOS 7:
sudo yum tāuta git wget flex bison gperf python cmake ninja−build ccache dfu−util - Ubuntu me Debian (kotahi whakahau ka pakaru ki nga rarangi e rua):
sudo apt−get install git wget flex bison gperf python python−pip python−setuptools cmake ninja −build ccache libffi −dev libssl −dev dfu−util - Arch:
sudo pacman −S −−e hiahiatia ana gcc git make flex bison gperf python−pip cmake ninja ccache dfu−util - Tuhipoka:
- Ka whakamahia e tenei aratohu te whaiaronga ~/esp i runga i te Linux hei kōpaki whakaurunga mo ESP-IDF.
- Kia maumahara kaore a ESP-IDF e tautoko i nga waahi i nga huarahi.
Tikina ESP-IDF
Hei hanga tono mo te EK057 kōwae, me hiahia koe ki nga whare pukapuka rorohiko e whakaratohia ana e Espressif i roto i te putunga ESP-IDF.
Ki te tiki ESP-IDF, hangahia he whaiaronga whakaurunga (~/esp) hei tango i te ESP-IDF ki te kati i te putunga me te 'git clone':
- mkdir −p ~/esp
- cd ~/esp
- git clone −−recursive https://github.com/espressif/esp−idf. git
Ka tangohia a ESP-IDF ki ~/esp/esp-idf. Tirohia nga Putanga ESP-IDF mo nga korero mo ehea te putanga ESP-IDF hei whakamahi i tetahi ahuatanga.
Whakaritea nga Utauta
I tua atu i te ESP-IDF, me whakauru ano e koe nga taputapu e whakamahia ana e te ESP-IDF, penei i te kaitoi, te patuiro, nga kohinga Python, me etahi atu. Ka whakaratohia e ESP-IDF he tuhinga whakaingoatia ko 'install.sh' hei awhina i nga taputapu. i te haere kotahi.
cd ~/esp/esp−idf
Whakaritea nga Taurangi Taiao
Ko nga taputapu kua whakauruhia kaore ano kia taapirihia ki te taurangi taiao PATH. Hei whakamahi i nga taputapu mai i te raina whakahau, me whakarite etahi taurangi taiao. Ka whakarato a ESP-IDF i tetahi atu tuhinga 'export.sh' e mahi ana. I roto i te tauranga e haere ana koe ki te whakamahi ESP-IDF, rere: tāuta .sh. $HOME/esp/esp−idf/export.sh
Inaianei kua rite nga mea katoa, ka taea e koe te hanga i to kaupapa tuatahi ki te waahanga EK057.
Waihangahia To Kaupapa Tuatahi
Timata i te Kaupapa
Inaianei kua reri koe ki te whakarite i to tono mo te waahanga EK057. Ka taea e koe te timata me te kaupapa timata/hello_world mai i te muaampte whaiaronga i ESP-IDF.
Tāruatia te tīmatanga/hello_world ki ~/esp directory:
cd ~/esp
cp −r $IDF_PATH/examples/get−started/hello_world .
He awhe o example kaupapa i roto i te exampte whaiaronga i ESP-IDF. Ka taea e koe te kape i tetahi kaupapa kia rite ki te whakaaturanga i runga ake nei ka whakahaere. Ka taea hoki te hanga exampi roto i te waahi, kaua e kape i te tuatahi.
Tūhono tō Pūrere
Na honoa to kōwae EK057 ki te rorohiko ka tirohia i raro he aha te tauranga rangatū ka kitea te kōwae. Ko nga tauranga Se-rial i Linux ka tiimata me te '/dev/tty' i o raatau ingoa. Whakahaerehia te whakahau i raro i nga wa e rua, i te tuatahi ka wetekina te papa, katahi ka honoa.
ls /dev/tty*
Tuhipoka:
Kia mau tonu te ingoa tauranga na te mea ka hiahia koe i nga mahi e whai ake nei.
Whirihora
Whakatere ki to whaiaronga 'hello_world' mai i te Hipanga 2.4.1. Tīmatahia he Kaupapa, whakatauhia te maramara ESP32 hei whaainga ka whakahaere i te taputapu whirihoranga kaupapa 'whirihora tahua'.
- cd ~/esp/hello_world
- IDF .py set−target esp32
- IDF .py menuconfig
Ko te whakatakoto i te whainga me te 'idf.py set-target esp32' me mahi kotahi, i muri i te whakatuwheratanga o tetahi kaupapa hou. Mena kei roto i te kaupapa etahi hanga me te whirihoranga, ka whakawāteahia, ka arawhitihia. Ka tiakina pea te whainga i roto i te taurangi taiao hei peke i tenei taahiraa. Tirohia te Kowhiri i te Whainga mo etahi atu korero. Mena kua tika nga mahi o mua, ka puta te tahua e whai ake nei:
Whakaatu 2: Whirihoranga Kaupapa – Matapihi Kainga
He rereke pea nga tae o te tahua i to tauranga. Ka taea e koe te whakarereke i te ahua me te whiringa '--style'. Whakahaerehia koa 'idf.py menuconfig --help'mo etahi atu korero.
Hangaia te Kaupapa
Hangaia te kaupapa ma te whakahaere:
idf .py hanga
Ma tenei whakahau e whakahiato te tono me nga waahanga ESP-IDF katoa, katahi ka whakaputa i te kaitautai, te ripanga wehewehenga, me nga raarangi tono.
- $ idf .py hanga
- Kei te whakahaere i te cmake i roto i te whaiaronga /path/to/hello_world/build
- Kei te whakahaere i te ”cmake −G Ninja −−warn−uninitialized /path/to/hello_world”… Whakatupato mo nga uara kaore i timatahia .

Mena kaore he hapa, ka mutu te hanga ma te whakaputa i te .bin binary firmware file.
Kohiko ki runga i te Pūrere
Whakamaramahia nga rua i hangaia e koe ki runga i to waahanga EK057 ma te whakahaere:
idf .py −p PORT [−b BAUD] flash
Whakakapia te PORT me te ingoa tauranga rangatū o to kōwae mai i te Hipanga: Honoa to Pūrere. Ka taea hoki e koe te huri i te reiti baud flasher ma te whakakapi i te BAUD me te reiti baud e hiahia ana koe. Ko te reeti baud taunoa ko 460800.Mo etahi atu korero mo nga tohenga idf.py, tirohia idf.py.
Tuhipoka:
Ko te kōwhiringa 'flash' ka hanga aunoa me te uira te kaupapa, no reira karekau e tika te whakahaere 'idf.py build'.

Ka wehe atu…
Te tautuhi pakeke ma te titi RTS…
Mena ka pai nga mea katoa, ka tiimata te tono "hello_world" i muri i to tango i te pekepeke i runga i te IO0 me te GND, ka whakaara ano i te papa whakamatautau.
Aroturuki
Ki te tirotiro mena kei te rere tonu te "hello_world", pato 'idf.py -p PORT monitor' (Kaua e wareware ki te whakakapi i te PORT me to ingoa tauranga rangatū).
Ka whakarewahia e tenei tono te tono IDF Monitor:
