TEST module WIFI3 -Click MikroE
avec 18F46K22

13/03/2016
version avec 18F46K22
sur breadboard (sans support Mikrobus)
Le module WIFI3 est relié par des fils Male-Femelle
Avec LCD2119 2x16 cars I2C
Alimentation 4 Piles 1,5V -> regulateur 3,3V..
Problemes rencontres:
*
Impossible d'utiliser le Timer0 ou Timer1 en mode interruption dans une subroutine et flux de data UART ?
Meme avec Timer1 en Low priority..
donc usage de Delay_ms..
BUG trouvé : manque parentheses dans Arme_Timer0() .. donc le Drapeau Flag_Timer0 n'etait JAMAIS mis à zero.
*
Difficulté pour detecter le "OK" dans le buffer2 de reception des datas en provenance du WIFI3-ESP8266
recherche de "OK" dans le buffer2 via strpbrk
est bien plus fiable que via strstr ou via strncmp

Test Timer1 tempo ..OK ( car ecriture appel Arme Timer OK !)
