Set Pin value
pin number: D0-D8, A0-A5, 0-8
value: HIGH, LOW, unsigned byte as string(0,255)

Example:

http://DERVICE_ADDRESS/set?pin=D2&value=HIGH

This will set state of digital pin 2 to HIGH

http://<DERVICE_ADDRESS>/set?pin=<PIN_NUMBER>&value=<VALUE>

Get Pin value
pin number: string D0-D8, A0-A5, 0-8
return: boolean string 0, 1

Example:

http://DERVICE_ADDRESS/get?pin=D2

This will get state of digital pin, in this case HIGH

http://<DERVICE_ADDRESS>/get?pin=<PIN_NUMBER>

Set Pin mode
pin number: D0-D8, A0-A5, 0-8
value: INPUT, OUTPUT, INPUT_PULLUP

Example:

http://DERVICE_ADDRESS/mode_set?pin=D2&value=OUTPUT

This will set mode of digital pin 2 to OUTPUT

http://<DERVICE_ADDRESS>/mode_set?pin=<PIN_NUMBER>&value=<VALUE>

Get Pin mode
pin number: D0-D8, A0-A5, 0-8
return: INPUT, OUTPUT, INPUT_PULLUP, UNKNOWN_PIN

Example:

http://DERVICE_ADDRESS/mode_get?pin=D2

This will get mode of digital pin, in this case OUTPUT

http://<DERVICE_ADDRESS>/mode_get?pin=<PIN_NUMBER>

Set PWM Pin value
pin number: string D3, D5, D8, 3, 5, 8
value: HIGH, LOW, unsigned byte as string (0,255)

http://<DERVICE_ADDRESS>/analog_set?pin=<PIN_NUMBER>&value=<VALUE>

Get Analog Pin value
pin number: string A0-A5
return: unsigned integer as string (0-1023)

http://<DERVICE_ADDRESS>/analog_get?pin=<PIN_NUMBER>

Write to I2C device

• I2C_ADDRESS - I2C device address, can skip it if perform only value write operation, unsigned byte as string (0-255)
• REGISTRY_NUMBER - I2C rigistry number, can skip it if perform only value write operation, unsigned byte as string (0-255)
• VALUE_TO_WRITE - RAW value to write to deivce, can be passed as only argument, unsigned integer as string
• MODE - number conversion mode, value to write can be translated to unsigned 8bit, 16bit, 24bit, 32bit number and writed to registry, can skip it if perform only value write operation, byte as string (8, 16, 24, 32)
• BUFFER - data that will be written to device as they are, can skip it if perform only value write operation, byte array

Example:
/twin_write?address=24&byte=16&reg=1&value=0
This will write to device on address 24 (0x18), value 0 as unsigned integer 16bit number to registry 1 (0x1)

Read from I2C device

• I2C_ADDRESS - I2C device address, unsigned byte as string (0-255)
  REGISTRY_NUMBER - I2C rigistry number, unsigned byte as string (0-255)
• MODE - number conversion mode, register can be translated from unsigned 8bit, 16bit, 24bit, 32bit and send as result of this reqiest, can skip it if DATA_LENGTH is present, unsigned byte as string (8, 16, 24, 32)
• DATA_LENGTH - how many bytes will be read from device and send as they are as result of this request, can skip it if MODE is present, byte as string (0-255)

Example:
/twin_read?address=24&byte=16&reg=5
This will read from device on address 24 (0x18), value as unsigned integer 16bit number from registry 5 (0x5) and send number as string

Write to UART device
DATA - data to send to UART device as TTL transmition, RAW data URL encoded
COMMIT - send end of line at the end (\r\n)

http://<DERVICE_ADDRESS>/uart_write?buffer=<DATA>&commit=<COMMIT>

Read from UART device
RAW data from UART input buffer, will be sent as result of this request
