    2 dfu-util libusb

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.

3.3.2 Tikina ESP-IDF
Hei hanga tono mo te ESP32-S2-SOLO-2U, me hiahia koe ki nga whare pukapuka rorohiko e whakaratohia ana e Espressif i roto i te whare 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':

  1. mkdir -p ~/esp
  2. cd ~/esp
  3.  Lgit clone –recursive https://github.com/espressif/esp-idf.git

Ka tangohia a ESP-IDF ki ~/esp/esp-idf. Whakawhitiwhiti Nga Putanga ESP-IDF mo nga korero mo te putanga ESP-IDF hei whakamahi i tetahi ahuatanga.

3.3.3 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.

  1. cd ~/esp/esp-idf
  2. ./install.sh

3.3.4 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 te tauranga ka whakamahia e koe te ESP-IDF, whakahaere:

  • . $HOME/esp/esp-idf/export.sh

Inaianei kua rite nga mea katoa, ka taea e koe te hanga i to kaupapa tuatahi i runga i te waahanga ESP32-S2-SOLO-2U.

3.4 Waihangahia To Kaupapa Tuatahi
3.4.1 Tīmatahia he Kaupapa
Inaianei kua rite koe ki te whakarite i to tono mo te waahanga ESP32-S2-SOLO-2U. Ka taea e koe te tiimata me te kaupapa timata/hello_world mai i muaampte whaiaronga i ESP-IDF.
Tāruatia te tīmatanga/hello_world ki ~/esp directory:

  1. cd ~/esp
  2. cp -r $IDF_PATH/examples/get-start/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.

3.4.2 Tūhono i tō Pūrere
Na honoa to kōwae ki te rorohiko ka tirohia i raro i te tauranga rangatū ka kitea te kōwae. Ko nga tauranga rangatū 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.

  1. ls /dev/tty*

Tuhipoka:
Kia mau tonu te ingoa tauranga na te mea ka hiahia koe i nga mahi e whai ake nei.

3.4.3 Whirihora
Whakatere ki to whaiaronga 'hello_world' mai i te Hipanga 3.4.1. Tīmatahia he Kaupapa, tautuhia te maramara ESP32-S2 hei whainga ka whakahaere i te taputapu whirihoranga kaupapa 'menuconfig'.

  1. cd ~/esp/hello_world
  2. idf.py kua whakaritea esp32s2
  3. idf.py menuconfig

Ko te whakarite i te whainga me te 'idf.py set-target ESP32-S2' 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:

ESPRESSIF ESP32-S2-SOLO-2U WiFi Kōwae - piki 2

Kei te whakamahi koe i tenei tahua hei whakarite i nga taurangi motuhake o te kaupapa, penei i te ingoa whatunga Wi-Fi me te kupuhipa, te tere o te tukatuka, me era atu. Ko te whakatuu kaupapa me te menuconfig ka pekehia mo "hello_word". Ko tenei exampKa rere me te whirihoranga taunoa
He rereke pea nga tae o te tahua i to tauranga. Ka taea e koe te huri i te ahua me te kōwhiringa '- -style' . Whakahaerehia koa 'idf.py menuconfig – -help' mo etahi atu korero.

3.4.4 Hangaia te Kaupapa
Hangaia te kaupapa ma te whakahaere:

  1. 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.

  19. hanga / tepu_wehenga / tepu-waahi.bin
  20. whakahaere ranei 'idf.py -p PORT flash'

Mena kaore he hapa, ka mutu te hanga ma te whakaputa i te .bin binary firmware file.

3.4.5 Kohiko ki runga i te Pūrere
Whakamaramahia nga rua i hangaia e koe ki runga i to waahanga ma te whakahaere:

  1. idf.py -p tauranga [-b BAUD] uira

Whakakapia te PORT me te ingoa tauranga rangatū o to papa ESP32-S2 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 ki 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'.
