Bẹrẹ EK057
Ohun ti O Nilo
Lati ṣe agbekalẹ awọn ohun elo fun module EK057 o nilo:
- 1 x EK057 module
- 1 x Espressif RF igbeyewo ọkọ
- 1 x USB-to-Serial Board
- 1 x Micro-USB okun
- 1 x PC nṣiṣẹ Linux
Ninu itọsọna olumulo yii, a mu ẹrọ ṣiṣe Linux bi example. Fun alaye diẹ sii nipa iṣeto ni Windows ati macOS, jọwọ tọka si Itọsọna Eto ESP-IDF.
Hardware Asopọ
- Solder module EK057 si igbimọ idanwo RF bi o ṣe han ni Nọmba 1.
- So igbimọ idanwo RF pọ si igbimọ USB-si-Serial nipasẹ TXD, RXD, ati GND.
- So USB-to-Serial Board pọ mọ PC.
- So igbimọ idanwo RF pọ mọ PC tabi oluyipada agbara lati mu ipese agbara 5 V ṣiṣẹ, nipasẹ okun USB Micro-USB.
- Lakoko igbasilẹ, so IO0 pọ si GND nipasẹ jumper kan. Lẹhinna, tan “ON” igbimọ idanwo naa.
- Ṣe igbasilẹ famuwia sinu filasi. Fun awọn alaye, wo awọn apakan ni isalẹ.
- Lẹhin igbasilẹ, yọ jumper kuro lori IO0 ati GND.
- Fi agbara soke igbimọ idanwo RF lẹẹkansi. EK057 yoo yipada si ipo iṣẹ. Chip naa yoo ka awọn eto lati filasi lori ibẹrẹ.
Akiyesi:
IO0 jẹ iṣiro inu inu ga. Ti o ba ṣeto IO0 lati fa soke, ipo Boot ti yan. Ti PIN yii ba fa-isalẹ tabi sosi ni lilefoofo loju omi, ipo Gbigbasilẹ ti yan. Fun alaye diẹ sii lori EK057, jọwọ tọka si EK057 Datasheet.
Ṣeto Ayika Idagbasoke
Ilana Idagbasoke Espressif IoT (ESP-IDF fun kukuru) jẹ ilana fun idagbasoke awọn ohun elo ti o da lori Espressif ESP32. Awọn olumulo le ṣe agbekalẹ awọn ohun elo pẹlu ESP32 ni Windows/Linux/macOS ti o da lori ESP-IDF. Nibi a mu ẹrọ ṣiṣe Linux bi example.

ESP-IDF yoo ṣe igbasilẹ si ~/esp/esp-idf. Kan si awọn ẹya ESP-IDF fun alaye nipa iru ẹya ESP-IDF lati lo ni ipo ti a fun.
Ṣeto Awọn irinṣẹ
Yato si ESP-IDF, o tun nilo lati fi sori ẹrọ awọn irinṣẹ ti ESP-IDF lo, gẹgẹbi olupilẹṣẹ, debugger, Python packages, bbl ESP-IDF pese iwe afọwọkọ ti a npè ni 'install.sh' lati ṣe iranlọwọ ṣeto awọn irinṣẹ. ninu ọkan lọ.
