Bido na EK057
Ihe Ị Chọrọ
Iji mepụta ngwa maka modul EK057 ị chọrọ:
- 1 x EK057 modul
- 1 x Espressif RF bọọdụ nnwale
- 1 x USB-na-Serial bọọdụ
- 1 x Micro-USB eriri
- 1 x PC na-arụ ọrụ Linux
Na ntuziaka onye ọrụ a, anyị na-ewere sistemụ arụmọrụ Linux dị ka example. Maka ozi ndị ọzọ gbasara nhazi na Windows na macOS, biko rụtụ aka na ESP-IDF Programming Guide.
Njikọ ngwaike
- Rere modul EK057 na bọọdụ nnwale RF dị ka egosiri na eserese 1.
- Jikọọ bọọdụ nnwale RF na bọọdụ USB-na-Serial site na TXD, RXD, na GND.
- Jikọọ eriri USB-na-Serial na PC.
- Jikọọ bọọdụ nnwale RF na PC ma ọ bụ ihe nkwụnye ọkụ iji mee ka ọkụ 5 V dị ike, site na eriri Micro-USB.
- Mgbe nbudata, jikọọ IO0 na GND site na jumper. Mgbe ahụ, gbanye “Gbanye” bọọdụ nnwale.
- Budata firmware n'ime flash. Maka nkọwa, lee akụkụ ndị dị n'okpuru.
- Mgbe nbudata, wepụ jumper na IO0 na GND.
- Kwado bọọdụ nnwale RF ọzọ. EK057 ga-agbanwe na ọnọdụ ọrụ. Ihe mgbawa ga-agụ mmemme site na ọkụ mgbe mmalite.
Mara:
IO0 nwere ezi uche dị n'ime. Ọ bụrụ na edobere IO0 ka ọ dọpụta, ahọpụtara ọnọdụ buut. Ọ bụrụ ntụtụ a dọdara ala ma ọ bụ aka ekpe na-ese n'elu mmiri, ahọpụtara ụdị nbudata ahụ. Maka ozi ndị ọzọ na EK057, biko rụtụ aka na EK057 Datasheet.
Tọlite gburugburu mmepe
Espressif IoT Development Framework (ESP-IDF maka mkpụmkpụ) bụ usoro maka mmepe ngwa dabere na Espressif ESP32. Ndị ọrụ nwere ike ịmepụta ngwa na ESP32 na Windows/Linux/macOS dabere na ESP-IDF. N'ebe a, anyị na-ewere sistemụ arụmọrụ Linux dị ka example.
