Er der nogle der leger med esp8266 esp-12
« Dato: Februar 02, 2015, 19:14:39 »
Er her nogle der har erfaring med esp8266 esp-12??

Dette er f.eks et ESP01 Modul
http://www.ebay.com/itm/ESP8266-Serial-Esp-01-WIFI-Wireless-Transceiver-Module-Send-Receive-LWIP-AP-STA-/221589414478?pt=LH_DefaultDomain_0&hash=item3397c2224e
Prisen for sådan et er ca. 21 Kr.

Her er der lidt data, kopieret fra siden
ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.

ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

Hvis man ønsker nogle "større" moduler. Findes der f.eks ESP12
http://www.ebay.com/itm/Newest-ESP8266-Serial-Wireless-WIFI-Transceiver-Module-Send-Receive-ESP-12-/171588030981?pt=LH_DefaultDomain_0&hash=item27f3719205
Den har flere I/O porte, og koster ca. 28 kr.

Portene kan bruges som I/O, Interrupt, pwm, i2c, OW
Og man kan programmer dem til f.eks at være webserver.
Har bestilt to ESP12 som jeg glæder mig til at komme til at lege med.
Kunne nemt forstille mig at de kan bruges istedet for PIC kredsen i mit projekt, også bliver det udvidet med WIFI.
