Update to libWiringPi 2.15

[nekuz0r]

npm install

The libWiringPi static library is no longer in the wiring-pi repository, but instead is compiled at installation time.

The libWiringPi is compiled across my libWiringPi repository @ Github. https://github.com/nekuz0r/wiringpi/

Official libWiringPi patchs are merged into this repository, but it offers some fixes and new functionalities.

List of modifications

• int pulseIn(pin, state) (reading PWM signal on a digital pin, same as arduino pulseIn (http://arduino.cc/en/Reference/pulseIn))
• Add support for pca9685 (led/servo driver)
• Fix mcp3422 support
• Remove some compilation warnings (cast to pointer from integer of different size)

  New in libWiringPi 2.15

• piBoardId(int* model, int* rev, int* mem, char\ marker)
• void softPwmStop(int pin)
• void softToneStop(int pin)
• SOFT_PWM_OUTPUT, SOFT_TONE_OUTPUT (pinMode)
• PI_MODEL_A, PI_MODEL_B, PI_MODEL_COMPUTE (piBoardId model id)
• const char* piModelNames[](indexed by piBoardId model id)
• const char* piRevisionNames[](indexed by piBoardId revision id)
• const char* piComputeRevisionNames[]

  New in wiring-pi 1.1.0

• Add piBoardId support
• Add softPwmStop support
• Add softToneStop support
• Add pulseIn function
• Add delay function
• Add delayMicroseconds function
• Add millis function
• Add micros function
• Add pca9685 support
• Remove precompiled dependencies (compiled at installation time)

  How is it implemented in wiring-pi ?

  softPwmStop

wpi.pinMode(pin, wpi.SOFT_PWM_OUTPUT);
wpi.softPwmStop(pin);

softToneStop

wpi.pinMode(pin, wpi.SOFT_TONE_OUTPUT);
wpi.softToneStop(pin);

piBoardId

piBoardId in wiring-pi (nodejs) returns an object

{
    "model": Number,
    "rev": Number,
    "mem": Number,
    "marker": String
};

if (boardId.model === wpi.PI_MODEL_A) {
    console.log('No network :(');
}

piModelNames

piModelNames is available as an array named PI_MODEL_NAMES

var boardId = wpi.piBoardId();
var modelName = wpi.PI_MODEL_NAMES[boardId.model];

piRevisionNames

piRevisionNames is available as an array names PI_REVISION_NAMES

var boardId = wpi.piBoardId();
var revisionName = wpi.PI_MODEL_NAMES[boardId.rev];

pulseIn

wpi.pinMode(pin, wpi.INPUT);
var microseconds = wpi.pulseIn(pin, wpi.HIGH);

PCA9685

wpi.pca9685Setup(pinBase, i2cAddress, pwmFrequency) // (pwmFrequency: 40Hz - 1000Hz);
wpi.pwmWrite(pin, value) // (value: 0 - 4096)

To calcule the pwm value from microseconds use the following formula:

Math.round((4096 / (1000000 / PWM_FREQ)) * microseconds)

delay, delayMicroseconds, millis, micros

wpi.delay(ms);
wpi.delayMicroseconds(us);
var ms = wpi.millis();
var us = wpi.micros();

Is everything ok ? Can i merge this update ?

[eugeneware]

LGTM. Merge away! :-) Sorry for the delay.

What's your npm username? I'll give you npm publish permissions as well.

[eugeneware]

I think I found you. I've given npm owner rights to the npm user leandregohy. Feel free to do an npm publish with the appropriate semver bump too.

[nekuz0r]

It's me, thank you :)
