# Mainboard Requires
|
||||
|
||||
- RAM: not less than 2KBytes
|
||||
- Serial: one serial (HardwareSerial or SoftwareSerial) at least
|
||||
|
||||
# Suppported Mainboards
|
||||
|
||||
- Arduino UNO and its derivatives
|
||||
- Arduino MEGA and its derivatives
|
||||
- [Iteaduino UNO](http://imall.iteadstudio.com/im130312001.html)
|

# Select the version of ESP8266 AT Firmware
|
||||
|
||||
At present, this library supports ESP8266 AT 0.18 version and 0.22 version. You
|
||||
can select one of them to fit your module by modifing this line in `ESP8266.h`:
|
||||
|
||||
#define USER_SEL_VERSION VERSION_18
|
||||
|
||||
If you want to select 0.22 version, it should be like below after modification:
|
||||
|
||||
#define USER_SEL_VERSION VERSION_22
|
||||
|
||||
|
||||
# Using SoftwareSerial
|
||||
|
||||
If you want to use SoftwareSerial to communicate with ESP8266, you need to modify
|
||||
the line in file `ESP8266.h`:
|
||||
|
||||
//#define ESP8266_USE_SOFTWARE_SERIAL
|
||||
|
||||
After modification, it should be:
|
||||
|
||||
#define ESP8266_USE_SOFTWARE_SERIAL
|
||||
|
||||
|
||||
# Hardware Connection
|
||||
|
||||
WeeESP8266 library only needs an uart for hardware connection. All communications
|
||||
are done via uart. In each example, you must specify the uart used by mainboard
|
||||
to communicate with ESP8266 flashed AT firmware.
|
||||
|
||||
## MEGA and WBoard Pro
|
||||
|
||||
For MEGA and WBoard Pro, `Serial1` will be used if you create an object (named wifi)
|
||||
of class ESP8266 in your code like this:
|
||||
|
||||
#include "ESP8266.h"
|
||||
ESP8266 wifi(Serial1);
|
||||
|
||||
The connection should be like these:
|
||||
|
||||
ESP8266_TX->RX1(D19)
|
||||
ESP8266_RX->TX1(D18)
|
||||
ESP8266_CH_PD->3.3V
|
||||
ESP8266_VCC->3.3V
|
||||
ESP8266_GND->GND
|
||||
|
||||
## UNO
|
||||
|
||||
To use SoftwareSerial, `mySerial` will be used if you create an object (named wifi)
|
||||
of class ESP8266 in your code like this:
|
||||
|
||||
#include "ESP8266.h"
|
||||
#include <SoftwareSerial.h>
|
||||
|
||||
SoftwareSerial mySerial(3, 2); /* RX:D3, TX:D2 */
|
||||
ESP8266 wifi(mySerial);
|
||||
|
||||
The connection should be like these:
|
||||
|
||||
ESP8266_TX->RX(D3)
|
||||
ESP8266_RX->TX(D2)
|
||||
ESP8266_CH_PD->3.3V
|
||||
ESP8266_VCC->3.3V
|
||||
ESP8266_GND->GND
|
||||
|
||||
# Attention
|
||||
|
||||
The size of data from ESP8266 is too big for arduino sometimes, so the library can't
|
||||
receive the whole buffer because the size of the hardware serial buffer which is
|
||||
defined in HardwareSerial.h is too small.
|
||||
|
||||
Open the file from `\arduino\hardware\arduino\avr\cores\arduino\HardwareSerial.h`.
|
||||
See the follow line in the HardwareSerial.h file.
|
||||
|
||||
#define SERIAL_BUFFER_SIZE 64
|
||||
|
||||
The default size of the buffer is 64. Change it into a bigger number, like 256 or more.
