Function Documentation

finalizeHardware()

void finalizeHardware

(

)

Resource clearing.

This function is called by the main OpenPLC routine when it is finalizing. Resource clearing procedures should be here.

Definition at line 200 of file unipi.cpp.

initializeHardware()

void initializeHardware

(

)

Initialization procedures.

This function is called by the main OpenPLC routine when it is initializing. Hardware initialization procedures should be here.

Definition at line 164 of file unipi.cpp.

mcp_adcRead()

int mcp_adcRead

(

int

chan

)

Definition at line 146 of file unipi.cpp.

mcp_adcSetup()

int mcp_adcSetup

(

int

i2cAddress

)

Definition at line 135 of file unipi.cpp.

readAdcThread()

void* readAdcThread

(

void *

args

)

Definition at line 67 of file unipi.cpp.

sleep_ms()

void sleep_ms

(

int

milliseconds

)

Definition at line 59 of file unipi.cpp.

updateBuffersIn()

void updateBuffersIn

(

)

Update internal buffers.

This function is called by the OpenPLC in a loop. Here the internal buffers must be updated to reflect the actual Input state. The mutex bufferLock must be used to protect access to the buffers on a threaded environment.

Definition at line 209 of file unipi.cpp.

updateBuffersOut()

void updateBuffersOut

(

)

Update output buffers.

This function is called by the OpenPLC in a loop. Here the internal buffers must be updated to reflect the actual Output state. The mutex bufferLock must be used to protect access to the buffers on a threaded environment.

Definition at line 232 of file unipi.cpp.

adcBuffer

unsigned int adcBuffer[2]

Definition at line 51 of file unipi.cpp.

adcBufferLock

std::mutex adcBufferLock

Definition at line 53 of file unipi.cpp.

inputPinMask

const int inputPinMask[MAX_INPUT] = { 7, 7, 0, 2, 4, 3, 5, 14, 11, 10, 13, 6, 12 }
