Long-Type Division

An exercise in typecasting:

double freq = 3;
long period = 1000/freq;

period will hold the value 333.

Arduino (AVR) error - avrdude: stk500_getsync(): not in sync: resp=0x00

In the context of Arduino, this error occurs when there are issues writing your program to the microcontroller.

Although there seem to be multiple potential sources to this problem, the mistake that I often find myself making is interfering with the RX/TX connections.

Therefore, try uploading your sketch after disconnecting any wires from digital i/o pins 0 and 1 (or whatever corresponds to RX/TX).

Change Language in SolidWorks to English

Where you looking to change the language. SW will use the language you specified during installation. If you looking to use English (thought you have installed a differnt language), then go to Tools > Options > General and select the following two options:

1. Use English language menus. (Available  if you specified another language during installation and the regional options  in the Windows Control Panel are set to  that language).

You must exit and re-start SolidWorks for this change to take place.

2. Use  English language feature and file names. (Displays feature names in the  FeatureManager design tree and automatically created file names in English.  Existing feature and file names in a foreign language do not update when you  select this option).

This option is available when Use English  language menus is cleared, you are running the SolidWorks software on a  foreign language operating system, and you installed SolidWorks for that foreign  language.
