Open Tools -> Serial Monitor in Arduino IDE, type FG and press Enter. It will respond with the name and version of just flashed GenericPin firmware. Play with commands (described below) to check how they work.
From now on, Arduino Board is ready to be managed by any device (controller) that is able to communicate through serial port (e.g. ESP8266board). Just connect Arduino RX with Controller TX, and connect Arduino TX with Controller RX, and Controller will be able to send commands to Arduino.
Examples of commands that can be sent:
Command
Description
CS P5 I0
Configure 5th digital pin for input without pull-up resistor.
DG P5
Get the digital value of 5th digital pin.
CE P9 OP
Configure 9th digital pin for PWM output and store the configuration in EEPROM to survive reboots.
PG P9
Get the PWM value of 9th digital pin.
AG P7
Get the value of 7th analog pin.

Parameters:
Pn Pin number prefixed with P, e.g.: P5
Vn Ouput Value prefixed with V, e.g.: V5, V1023
Example:
Command
Description
PE P5 V42
Set the PWM output of 5th digital pin to 42, the state will be restored after Arduino restart.
PWM Pin Get
Get the state of PWM output pin (the returned value will be in range [0-1023]).
Command
Description
PG Pn
Get Pin value
Parameters:
Pn Pin number prefixed with P, e.g.: P5,P11
Example:
Command
Description
PG P11
Get the PWM value previusly set for 11th pin, e.g.: OK V42
Analog Get
Get the analog pin state (the value from one of ADC pins). The value will be in range [0-1023].
Command
Description
AG Pn
Get Pin value
Parameters:
Pn Pin number prefixed with P, e.g.: P6
Example:
Command
Description
AG P6
Get the analog input value from ADC on 6th analog pin, e.g: OK V512
Name Set
Assign a name to Arduino instance.
Command
Description
NS NewName
Store NewName in EEPROM.
NE NewName
Store NewName in EEPROM.
Parameters:
NewName A name to be assigned to arduino board, e.g.: Socket3
Example:
Command
Description
NS Socket3
Name the Arduino board Socket3.
Name Get
Returns the previously assigned name of the Arduino board.
Command
Description
NG
Return previously assigned board name from EEPROM
Example:
Command
Description
NG
Return the name previously assigned with NS NewName command, e.g.: OK Socket3
Firmware Set
Various commands for modifying the state of the Arduino board.
Command
Description
FS A
Reset all the data in EEPROM to its initial state, restart Arduino
FS P
Reset port configuration in EEPROM, restart Arduino
FS R
Restart Arduino
Example:
Command
Description
FS R
Restart Arduino
Firmware Get
Various commands for getting the state of the Arduino board.
Command
Description
FG
Get the firmware full name
FG V
Get the firmware version
FG N
Get the firmware name
Example:
Command
Description
FG V
Return the firmware version, e.g. OK 1.0.0
Notes:
Nothing will be returned as a response to an invalid command by default. That is a workaround for ESP8266 sending some gibberish to UART on (re)start.
Put word DEBUG before the command in order to debug it (e.g. DEBUG PS P13 V512). As the result, if command is ok, the usual "OK ..." answer will be returned, if command is wrong, the error message will be returned.
Both PWM and Analog values are normalized to the same 10-bit basis: min = 0, max = 1023.
