| | * MEGA+WiFi R3 ATmega2560+ESP8266, flash 32MB, USB-TTL CH340G, Micro-USB de ROBODYN. |
| | * Afficheur Touchscreen TFT ILI9486. |
| | * Emetteur/Récepteur RF433MHz. |
| | * Module RTC I2C 24C32 mémoire DS1307 horloge. |
| | * Une alimentation 220v/12V |
| | |
| | Pour mon projet, je vais essayé d'utiliser mon Mega-WIFI de Robodyn. \\ |

| | En gros il s'agit d'un Arduino Mega couplé avec un ESP sur la même carte au dimension du Mega.\\ |
| | Grace à des minidip, on peu utiliser l'arduino ou l'esp seul, relié par le port RS232 TX3/RX3 du mega à l'ESP, ou ensemble.\\ |
| | Du coup on a un arduino Mega avec toute sa mémoire et sa puissance, que l'on peu connecter au WIFI vie l'ESP. |

| | Il y a sans doute d'autre site, mais ceux cités permette déjà de bien comprendre le fonctionnement.\\ |
| | Elle ne fonctionne pas exactement comme une carte MEGA, notamment au niveau des interruptions. |
| | |
| | <code> |
| | Serials 0 (RX) and 1 (TX); |
| | Serial 1s 19 (RX) and 18 (TX); |
| | Serial 2s 17 (RX) and 16 (TX); |
| | Serial 3s 15 (RX) and 14 (TX). |
| | Used to receive (RX) and transmit (TX) TTL serial data. |
| | Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip. |
| | |
| | External Interrupts: |
| | 2 (interrupt 0), |
| | 3 (interrupt 1), |
| | 18 (interrupt 5), |
| | 19 (interrupt 4), |
| | 20 (interrupt 3), |
| | 21 (interrupt 2). |
| | These pins can be configured to trigger an interrupt on a low level, a rising or falling edge, or a change in level. |
| | See the attachInterrupt() function for details. |
| | |
| | PWM: 2 to 13 and 44 to 46. |
| | Provide 8-bit PWM output with the analogWrite() function. |
| | |
| | SPI: 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS). |
| | These pins support SPI communication using the SPI library. |
| | The SPI pins are also broken out on the ICSP header, which is physically compatible with the Uno and the old Duemilanove and Diecimila boards. |
| | |
| | LED: 13. There is a built-in LED connected to digital pin 13. |
| | When the pin is HIGH value, the LED is on, when the pin is LOW, it’s off. |
| | |
| | TWI: 20 (SDA) and 21 (SCL). |
| | Support TWI communication using the Wire library. |
| | Note that these pins are not in the same location as the TWI pins on the old Duemilanove or Diecimila boards. |
| | The Mega 2560 has 16 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). |
| | By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and analogReference() function. |

| | Pour programmer le Mega ou l'ESP voici le tableau de switch : |

| | Voici où change le port série entre le mega et l'ESP :\\ |
| | {{:projets:2.png?300|}} |
| | |
| | Après avoir changer le mode sur la carte, il faut configurer l'IDE.\\ |
| | Il est important quand l'ESP est programé de presser le bouton "MODE"\\ |
| | After choosing the mode of the board can proceed to set up the IDE \\ |
| | It is important that when the ESP8266 module is programming, it is necessary to press the button “Mode” \\ |
