For example, the two versions of CreateFile are CreateFileW (the Unicode version) and CreateFileA (the single-byte character version). To facilitate programs that represent strings either with Unicode (multi-byte characters) or single-byte characters, many Win32 functions (including CreateFile) come in two versions, one which expects string arguments in Unicode format and one which expects single-byte character strings. The basic problem here is that when Visual Studio creates a new project, by default it sets the character type to Unicode in the project settings.

To run (this example sends the characters "S365" via COM1): To compile with cl, the Microsoft compiler: Command line arguments are used to specify the text Written by Ted Burke - last updated 6-12-2011 SerialSend.c - This program sends text via serial port It just sends one word of text to an external device via a user-specified COM port.

Here’s the little Windows program of mine that he’s using. At the moment, one of the engineers in my Robotics module (Anthony Gaule) is trying to send commands from a machine vision program running on his laptop to a miniature SCARA arm that he has built (controlled by a dsPIC30F4011).
#RASPBIAN USB SERIAL TERMINAL PROGRAM TO SEND TEXT FILE PC#
When I’m building robots, I sometimes find it useful to send short commands from the PC to a microcontroller (usually a dsPIC30F4011) in real-time via a USB-to-serial adapter. The updated version is available from the SerialSend page. NOTE (18-12-2012): Since posting this, I have updated SerialSend to add some additional useful features and make more robust.
