* (19)OK (v1.0) Trying port to WIZNET5500 BLYNK IOT app (look: https://blynk.io/)
|
||||
* TODO:
|
||||
* Add DNS resolve before BLYNK app running to <blynk-cloud.com>
|
||||
* OK (v1.1) Add LED_ON/LED_OFF handle on LED D13 BLYNK Android application
|
||||
* GPIO OUT - works OK (look ./Application/Blynk/blynkDependency.c digitalWrite(..) && pinMode(..))!
|
||||
* OK Add printout <blynk> server metrics on start-up
|
||||
* Need to try next:
|
||||
* GPIO IN (via virtual pins?)
|
||||
* Virtual IN/OUT
|
||||
* Analog Read/Write
|
||||
* Restore pins state on board reboot
|
||||
* OK ??3.Try fix frequent reconnection with blynk server - every ~22sec may be this OK.
|
||||
* Need compare local blynk.c code with modern <blynk> library - (Too old version here - 0.2.1 (On git blynk March 2019 - 0.6.x) )
|
||||
*
|
||||
* (3) Trying WIZNET5500 init with using official Wiznet ioLibrary_Driver
|
||||
* working ping, assign static IP
|
||||
* LED1 = ON when phy_link detected
|
||||
* and loopback test on TCP-IP:5000 and UDP:3000 ports.
|
||||
* use Hercules terminal utility to check network connection see:
