| - | ===== Preparación ===== | ||
| - | |||
| - | La placa hay que hacerle unos cambios para que sea compatible con Blynk. | ||
| - | |||
| - | Para conectar el Robotdyn mega a Blynk necesitas hacer los siguientes pasos: | ||
| - | |||
| - | - Flash ESP | ||
| - | - Subir código | ||
| - | - Ajuste de switches | ||
| - | |||
| - | This was a quick overview. Now let’s go to do it. | ||
| - | |||
| - | ==== Flash ESP ==== | ||
| - | |||
| - | I flashed new official firmware from here: https://espressif.com/en/support/download/sdks-demos 30 | ||
| - | I used version v1.5.4 and patch V1.5.4.1 Patch_20160704 | ||
| - | |||
| - | I used Flash Download Tools v3.4.4 tool from here: https://espressif.com/en/support/download/other-tools 17 | ||
| - | |||
| - | I used instructions from here: http://remotexy.com/en/help/esp8266-firmware-update/ 20 | ||
| - | |||
| - | In the bin folder coming from the .zip file are the files needed to flash the ESP8266. | ||
| - | |||
| - | Please note that in the folder from the patch is a newer esp_init_data_default.bin file to be used. | ||
| - | In the AT folder under the bin file are folders and files. | ||
| - | |||
| - | In the README.txt file are instruction on what file to store where in the ESP8266 memory location. | ||
| - | As the Robotdyn UNO + WiFi has ESP8266 which is stated to be 8Mb I used: | ||
| - | |||
| - | Which means files from the 512+512 were used. | ||
| - | |||
| - | {{ :anakino_aquarium_v2:flash_config.png |}} | ||
| - | |||
| - | After flashing the ESP it finally started to reply to AT commands. | ||
| - | |||
| - | Flash size 32Mbit: 512KB+512KB | ||
| - | <code> | ||
| - | boot_v1.2+.bin 0x00000 | ||
| - | user1.1024.new.2.bin 0x01000 | ||
| - | esp_init_data_default.bin 0x3fc000 (optional) | ||
| - | blank.bin 0x7e000 & 0x3fe000 | ||
| - | </code> | ||
| - | |||
| - | ==== Upload code ==== | ||
| - | |||
| - | Para subir el código es importante fijarse en los interruptores: | ||
| - | <code> | ||
| - | 1- OFF | ||
| - | 2- OFF | ||
| - | 3- ON | ||
| - | 4- ON | ||
| - | 5- OFF | ||
| - | 6- OFF | ||
| - | 7- OFF | ||
| - | RXD0 x TXD0 | ||
| - | </code> | ||
| - | ¡Ten cuidado con la posición de los interruptores! | ||
| - | - Para esto deben estar el 3.ON 4.ON los otros en OFF. | ||
| - | - I have downloaded an example 5 and made some changes. | ||
| - | - You need to change Serial from 1 to 3 like this: #define EspSerial Serial3. | ||
| - | (exactly this i was solving four months) | ||
| - | Code should look like this: | ||
| - | |||
| - | <code> | ||
| - | #define BLYNK_PRINT Serial | ||
| - | |||
| - | |||
| - | #include <ESP8266_Lib.h> | ||
| - | #include <BlynkSimpleShieldEsp8266.h> | ||
| - | |||
| - | // You should get Auth Token in the Blynk App. | ||
| - | // Go to the Project Settings (nut icon). | ||
| - | char auth[] = "..."; | ||
| - | |||
| - | // Your WiFi credentials. | ||
| - | // Set password to "" for open networks. | ||
| - | char ssid[] = "..."; | ||
| - | char pass[] = "..."; | ||
| - | |||
| - | // Hardware Serial on Mega, Leonardo, Micro... | ||
| - | #define EspSerial Serial3 | ||
| - | |||
| - | // or Software Serial on Uno, Nano... | ||
| - | //#include <SoftwareSerial.h> | ||
| - | //SoftwareSerial EspSerial(2, 3); // RX, TX | ||
| - | |||
| - | // Your ESP8266 baud rate: | ||
| - | #define ESP8266_BAUD 115200 | ||
| - | |||
| - | ESP8266 wifi(&EspSerial); | ||
| - | |||
| - | void setup() | ||
| - | { | ||
| - | // Debug console | ||
| - | Serial.begin(9600); | ||
| - | delay(10); | ||
| - | |||
| - | // Set ESP8266 baud rate; | ||
| - | EspSerial.begin(ESP8266_BAUD); | ||
| - | delay(10); | ||
| - | |||
| - | Blynk.begin(auth, wifi, ssid, pass); | ||
| - | // You can also specify server: | ||
| - | //Blynk.begin(auth, wifi, ssid, pass, "blynk-cloud.com", 80); | ||
| - | //Blynk.begin(auth, wifi, ssid, pass, IPAddress(192,168,1,100), 8080); | ||
| - | } | ||
| - | |||
| - | void loop() | ||
| - | { | ||
| - | Blynk.run(); | ||
| - | // You can inject your own code or combine it with other sketches. | ||
| - | // Check other examples on how to communicate with Blynk. Remember | ||
| - | // to avoid delay() function! | ||
| - | } | ||
| - | |||
| - | </code> | ||
| - | |||
| - | Esto es el código mínimo para conectar la placa y probarlo. | ||
| - | Cuando la conexión sea satisfactoria podrás ver como el status de tu aplicación Blynk pasa a estar ONLINE. | ||
| - | |||
| - | ==== Ajuste de los interruptores ==== | ||
| - | |||
| - | Para que funcione el código deben estar los interruptores así. | ||
| - | <code> | ||
| - | 1- ON | ||
| - | 2- ON | ||
| - | 3- ON | ||
| - | 4- ON | ||
| - | 5- OFF | ||
| - | 6- OFF | ||
| - | 7- OFF | ||
| - | RXD3 x TXD3 | ||
| - | </code> | ||
| - | 3.1. esto permite la comunicación entre el MEGA y el ESP8266 y el puerto serie en tu PC. | ||
| - | This setting let you see serial print and at the same time it will communicate with ESP. | ||
| - | 3.2. switch near ICSP set to | ||
| - | After moving all necessary switches go to the next step. | ||
| - | |||
| - | Conecta la placa, abre tu aplicación y tomate una cerveza! | ||
| - | |||
| - | That’s all folks… | ||
| - | |||
| - | Problemática. | ||
| - | |||
| - | Wrong Dip-setting | ||
| - | Weak WIFI signal | ||
| - | Wrong SSID, PASS, AUTH | ||
| - | Use external power supply | ||
| - | Possibly it could be high baud of ESP (never happen to me). You can reduce it to 9600 (to the same level as Serial.print) | ||
| - | For reducing baud use this | ||
| - | <code>AT+UART_DEF=9600,8,1,0,0</code> | ||
| - | or | ||
| - | |||
| - | <code>AT+CIOBAUD=9600</code> | ||
| - | it should reply | ||
| - | |||
| - | <code>OK</code> | ||
