Device subclasses
We talked in this page about the necessity to implement a subclass for each device type. Every device has its own registers, variable names, inputs and outputs (AKA endpoints) so all these attributes need to be defined by the subclass. The following device subclasses are available from the uSWAP library:
SWAP device providing 8-binary outputs and 4 PWM outputs. This device is usually implemented with an output-board. Binouts condenses all endpoints in only two registers. First register (1-byte) contains the information about all the eight binary outputs. The second register (4-bytes) does the same for the PWM outputs.
Binary (ON/OFF) outputs. Each bit represents the state of a binary output. Lower output (BINOUT0) is the less significant bit
uint8_t binOutputs[8];PWM (0-255) outputs. Each byte represents the level of a PWM output. Lower output (PWMOUT0) is the less significant byte.
uint8_t pwmOutputs[4];Endpoints can be accessed from mqttgateway (via MQTT and HTTP) by means of the following names:
"BINOUT0" : binary endpoint 0
"BINOUT1" : binary endpoint 1
"BINOUT2" : binary endpoint 2
"BINOUT3" : binary endpoint 3
"BINOUT4" : binary endpoint 4
"BINOUT5" : binary endpoint 5
"BINOUT6" : binary endpoint 6
"BINOUT7" : binary endpoint 7
"PWMOUT0" : PWM output 0
"PWMOUT1" : PWM output 1
"PWMOUT2" : PWM output 2
"PWMOUT3" : PWM output 3
