Ukuze uhlole ukuthi i-“hello_world” iyasebenza ngempela yini, thayipha i-idf.py -p PORT monitor (Ungakhohlwa ukushintsha i-PORT ngegama lakho lembobo yomkhiqizo).
Lo myalo wethula uhlelo lokusebenza lokuqapha:
$ idf.py -p /dev/ttyUSB0 qapha Isebenzisa i-idf_monitor kumkhombandlela […]/esp/hello_world/build Isebenzisa “python […]/esp-idf/tools/idf_monitor.py -b 115200 […]/esp/hello_world / build/hello-world.elf”… — idf_monitor on /dev/ttyUSB0 115200 — — Yeka: Ctrl+] | Imenyu: Ctrl+T | Usizo: Ctrl+T elandelwa u-Ctrl+H — ets Jun 8 2016 00:22:57 rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) ets Jun 8 2016 00:22:57 ...
Ngemva kokuqala kanye namalogi okuxilonga askrolela phezulu, kufanele ubone "Sawubona mhlaba!" ephrintwe uhlelo lokusebenza.
… Sawubona Mhlaba! Iqala kabusha kumasekhondi angu-10… I (211) cpu_start: Iqala isihleli ku-APP CPU. Iqala kabusha emizuzwaneni engu-9… Iqala kabusha emizuzwaneni engu-8… Iqala kabusha emizuzwaneni engu-7...
Ukuze uphume kumonitha we-IDF sebenzisa isinqamuleli esithi Ctrl+].
Uma ukuqapha kwe-IDF kwehluleka ngemva nje kokulayisha, noma, uma esikhundleni semilayezo engenhla, ubona udoti ongahleliwe ofana nalokhu okunikezwa ngezansi, ibhodi lakho cishe lisebenzisa ikristalu engu-26MHz. Imiklamo eminingi yebhodi lokuthuthukisa isebenzisa i-40MHz, ngakho-ke i-ESP-IDF isebenzisa le mvamisa njengenani elizenzakalelayo.
