TCP protocol to control I/O ports. Current version: 1.0
Every transmission ends with "\n". Every number transmitted must be an integer.
The server sends HELLO 1.0, where 1.0 is the protocol version.
Client answers OK if protocol is supported, UNKNOWN if not.
The server can try to handshake with lower protocol versions if handshake fails.
Lists all available I/O Ports.
Answer: OK [obj,obj,...] where obj is a JSON representation of the structure described in ahio.abstract_driver.AbstractDriver.available_pins. Here id must be an integer. For example:
[{
"id": 1,
"name": "Pin 1",
"analog": {
"input": true,
"output": false,
"read_range": [
0,
1023
],
"write_range": null
},
"digital": {
"input": true,
"output": true,
"pwm": true
}
}]Sets the direction of PORT to INPUT or OUTPUT.
Answer: OK or ERROR MSG, where MSG is a message that describes the error that occurred.
Returns the direction PORT is set to.
Answer: OK INPUT|OUTPUT or ERROR MSG
Sets PORT to DIGITAL or ANALOG.
Answer: OK or ERROR MSG, where MSG is a message that describes the error that occurred.
Gets the type of PORT.
Answer: OK DIGITAL|ANALOG or ERROR MSG
Sets PORT output to HIGH or LOW.
Answer: OK or ERROR MSG, where MSG is a message that describes the error that occurred.
Sets PORT output to VALUE, where VALUE is a number in range of obj.analog.write_range. See LISTPORTS.
Answer: OK or ERROR MSG, where MSG is a message that describes the error that occurred.
Sets PORT output to a PWM with dutycycle VALUE, where VALUE is a number between 0 and 1.
Answer: OK or ERROR MSG, where MSG is a message that describes the error that occurred.
Reads the tension in PORT.
Answer: HIGH or LOW as read on the port, or ERROR MSG, where MSG is a message that describes the error that occurred.
Reads the tension in PORT.
Answer: An integer in range of obj.analog.read_range (See LISTPORTS), or ERROR MSG, where MSG is a message that describes the error that occurred.
Returns the possible values for analog reference.
Answer: OK V1 V2 V3, where VN is a value that can be used as
analog reference.
Sets the analog reference to REFERENCE. REFERENCE must be in the list returned by ANALOGREFERENCES. See ahio.abstract_driver.AbstractDriver.set_analog_reference for more information regarding this function.
Answer: OK or ERROR MSG, where MSG is a message that describes the error that occurred.
Returns the analog reference for PORT or the global analog reference case PORT is ommited.
Answer: OK REFERECE or ERROR MSG, where MSG is a message that describes the error that occurred.
Sets the PWM frequency of PORT to FREQUENCY. If PORT is omitted, sets it globally.
Answer: OK or ERROR MSG, where MSG is a message that describes the error that occurred.
