\"IMG_8921_web\"<\/a>Do minul\u00e9ho t\u00fddne jsem pou\u017e\u00edval pro svoje pokusy s ESP8266 pouze modul ESP-01 (na obr\u00e1zku \u00fapln\u011b vlevo). Modul to je velmi levn\u00fd, ale bohu\u017eel tak\u00e9 velmi omezen\u00fd – v podstat\u011b se daj\u00ed pou\u017e\u00edt pouze dva I\/O piny, tak\u017ee jsem skon\u010dil na oblig\u00e1tn\u00edm WiFi teplom\u011bru (\u010didlo DS18B20 je na fotce tak\u00e9 patrn\u00e9). Za\u010d\u00e1tkem prosince jsem ale na\u0161el a objednal modul ESP-03, kter\u00fd sice dorazil koncem prosince, jenom\u017ee n\u00e1s zas\u00e1hl osud v podob\u011b m\u00e9 m\u00e1my (sedmdes\u00e1tilet\u00e1 \u017eensk\u00e1, p\u0159iv\u00e1zan\u00e1 k psovi a n\u00e1led\u00ed – co by se asi mohlo st\u00e1t \u017ee…). M\u00e1ma tedy zat\u00edm bydl\u00ed s nohou v gypsu u n\u00e1s (i se psem… Grrrr…) a j\u00e1 m\u00e1m m\u00ed\u0148 \u010dasu na svoje hra\u010dky. Minul\u00fd t\u00fdden jsem v\u0161ak u\u017e nevydr\u017eel a po\u017e\u00e1dal p\u0159\u00edtelkyni o zap\u00e1jen\u00ed modulu na univerz\u00e1ln\u00ed desku. Zap\u00e1jen\u00ed dopadlo dob\u0159e<\/p>\n

\"2015-01-26<\/a> \"2015-01-26<\/a><\/p>\n

a tak jsem mohl modul osadit do breadboardu na otestov\u00e1n\u00ed.<\/p>\n

\"IMG_8919_web\"<\/a><\/p>\n

Pro nahr\u00e1n\u00ed firmware jsem p\u0159ipojil b\u011b\u017en\u00fd FTDI p\u0159evodn\u00edk, kter\u00fd mi zbyl z pokus\u016f s MultiWii – pot\u0159ebuji sice t\u00edm p\u00e1dem dva USB porty, ale na\u0161t\u011bst\u00ed jich m\u00e1m zat\u00edm dost.<\/p>\n

Firmware je stejn\u00fd do obou modul\u016f, subjektivn\u011b se chovaj\u00ed oba stejn\u011b, jen dosah WiFi se mi zd\u00e1 lep\u0161\u00ed u ESP-01 s dr\u00e1tovou ant\u00e9nou. Netu\u0161\u00edm, jak\u00e1 je vyza\u0159ovac\u00ed charakteristika keramick\u00e9 ant\u00e9ny na ESP-03, tak\u017ee je tak\u00e9 mo\u017en\u00e9, \u017ee jsem s testovac\u00edm telefonem st\u00e1l mimo v\u00fdkonov\u00fd lalok. Na druhou stranu se mi zd\u00e1 modul ESP-03 chladn\u011bj\u0161\u00ed, ne\u017e ESP-01. M\u016fj USB V\/A metr ukazuje stabiln\u00ed odb\u011br cca 30mA.<\/p>\n

Posledn\u00edm p\u0159\u00edr\u016fstkem je dnes z\u00edskan\u00fd ESP-07 (na tituln\u00edm sn\u00edmku ten vpravo), kter\u00fd m\u00e1 oproti ESP-03 v\u00fdhodu v osazen\u00ed st\u00edn\u011bn\u00ed a vyveden\u00ed vstupu A\/D p\u0159evodn\u00edku. Otestovat jsem ho ale je\u0161t\u011b nestihl.<\/p>\n

Nejnov\u011bj\u0161\u00edm \u010c\u00ednsk\u00fdm p\u0159\u00edr\u016fstkem, kter\u00fd je\u0161t\u011b nem\u00e1m ani objednan\u00fd je pak modul ESP-201, kter\u00fd m\u00e1 vyveden\u00e9 i rozhran\u00ed na SD kartu. Zat\u00edm jsem ale nena\u0161el specifikace SD bootloaderu, tak\u017ee si na zakoupen\u00ed je\u0161t\u011b chv\u00edli po\u010dk\u00e1m…<\/p>\n
