Patched FTDIUSBSerialDriver kext has to be unloaded/reloaded after reboot (OSX 10.10). Any ideas?

由 懵懂的女人 提交于 2019-12-11 09:32:34
问题 I'm exchanging data between a bare-bone Arduino and openFrameworks via a serial UART FTDI connection. I'm using a patched FTDI driver to achieve higher BAUD rates on OSX. FTDIChip calls it "Aliasing VCP Baud Rates". See: http://spin.atomicobject.com/2013/06/23/baud-rates-ftdi-driver-mac/ https://github.com/arminbw/wiretouch/blob/v0.21/perl/modify-ftdi-driver-settings.pl This worked until recently. Since upgrading to OSX 10.10 I have to manually unload and reload the kext to make it work: sudo

Passing a void function as an argument to another function

由 ╄→гoц情女王★ 提交于 2019-12-08 13:41:07
问题 I'm trying to pass a void function to another void function, unsuccessfully so far. So I created this function inside the class called ExitButton like this. ExitButton.h: class ExitButton{ void setup(void (*_setup)); }; Then I include that class into another class like this. ofApp.h: include "ExitButton.h" class ofApp : public ofBaseApp{ void update(); void setup(); StartButton *startButton; } So in my ofApp.cpp I want to call the update function like this: void ofApp::update(){ exitButton-

How to port corebluetooth from Objective C to Objective C++

由 China☆狼群 提交于 2019-12-08 12:15:47
问题 I was hoping to get some help with a project I'm working on. I'm currently trying to rework this code https://github.com/djwait/CoreBluetoothExample written in Objective -c into Openframeworks ios Objective c++. However I am a complete beginner to Objective -c and am feeling lost as to how to proceed. The aim is to get access to the variable uint16_t heartRate (from the original app) and use it in c++ code. More than anything I’m confused as to how the original code is creating an

Using the Parent constructor to initialize a child class

由 岁酱吖の 提交于 2019-12-07 15:14:25
I want to create a general class called Button that others inherit from, so that for example I can have StartButton, ContinueButton, etc. There are certain values regardless of the different properties that I want to start with the constructor since they will always be needed so I built my own Button Class like this: #pragma once #include "ofMain.h" class Button { public: Button(ofPoint _pos, string _text); virtual void setup(); virtual void update(); virtual void draw(); protected: ofTrueTypeFont buttonName; ofPoint pos; string text, fontName; bool isClicked; int buttonFader, buttonFaderVel;

how can I fix xcode compiling everything all the time?

问题 This question was migrated from Super User because it can be answered on Stack Overflow. Migrated 10 years ago . I've started to use XCode and it seems to work, well, most of it. The annoying thing is it compiles all the source files, even those that didn't change, each and every time. I'm getting the grips with openframeworks and I waste time compiling the openframeworks source files every time although they don't change. Here are my IDE and machine details: XCode Version 3.1.2 Component

Getting coordinates for glFrustum

由 馋奶兔 提交于 2019-12-05 02:05:03
问题 I just started reading about OpenGL topics, specifically about Viewing for my current needs. I am trying to understand glFrustum for a perspective projection of objects that I have drawn on the screen and as I understand glFrustum would make the farther objects smaller than the nearer objects. I am using openFrameworks here for drawing objects such as Image / Box etc. and here's a short example of what I am trying to do: openFrameworks draw method draw() { glMatrixMode(GL_PROJECTION);

Off-axis projection with glFrustum

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-04 23:41:26
问题 I am trying to do an off-axis projection of a scene with OpenGL and I gave a read to the document to Robert Kooima's off-axis projection and have a much better idea now of what actually has to be done but there are still some pieces which I am finding tricky here. I got to know of the off-axis projection code for OpenGL to be somewhat as follows: Code 1: glMatrixMode(GL_PROJECTION); glLoadIdentity(); glFrustum(fNear*(-fFov * ratio + headX), fNear*(fFov * ratio + headX), fNear*(-fFov + headY),

problem saving openGL FBO larger than window

由 对着背影说爱祢 提交于 2019-12-04 18:25:11
问题 I'm rendering into an OpenGL offscreen framebuffer object and like to save it as an image. Note that the FBO is larger than the display size. I can render into the offscreen buffer and use it as texture, which works. I can "scroll" this larger texture through the display using an offset, which makes me confident, that I render into a larger context than the window. If I save the offscreen buffer to an image file it always gets cropped. The code fragment for saving is: void ofFBOTexture:
