usbserial - Managing serial conversation between Linux and Arduino -


i want write binary transfer to/from arduino other side through usb. right now, i'm doing in ascii, , it's easy. ascii, can see junk until 2 sides synchronize. binary, difficult distinguish data noise. there standard way reset connection , reliable byte stream out? can send break , force arduino reset somehow? looking suggestion on best practices.

for reliable communications, need include protocol binary data,

  • you know when things have gone wrong
  • you can in sync

a detailed description of serial framing can found here

as example, point-to-point protocol (ppp) provides simple method of framing sections of data surrounding them special character guaranteed never occur on it's own in binary stream (there escaping mechanism allow happen). receiver can use framing characters synchronise.

you (depending on how bad if erroneous data gets through) add checksum or crc messages - ppp calls frame-check sequence or fcs.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
