The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Send byte record to RS232, Microcontroller

Asked by MrSimpson in Delphi Programming, Delphi IDE, Miscellaneous Hardware

Tags: Borland, Delphi, BDS 2005

Hello!

I have a Luminary Micro Controller where all code examples are written in C.
From their support I've been told that I need to open a COM port in Delphi and
send a packet of bytes to the microcontroller.

  The C packet looks like this:
   //
    // Construct a set target position command.
    //
    g_pucData[0] = TAG_CMD;
    g_pucData[1] = 0x09;
    g_pucData[2] = CMD_SET_PARAM_VALUE;
    g_pucData[3] = PARAM_TARGET_POS;
    g_pucData[4] = g_ulTargetPosition & 0xff;
    g_pucData[5] = (g_ ulTargetPosition >> 8) & 0xff;
    g_pucData[6] = (g_ ulTargetPosition >> 16) & 0xff;
    g_pucData[7] = (g_ ulTargetPosition >> 24) & 0xff;
    g_pucData[8] = {checksum};

Bytes in the packet should be:
0xFF 0x09 0x13 0x08 0x00 0xC8 0x00 0x00 0x13

In Delphi I'm using a component called TSerialPortNG to open the COM port (COM3) and send data.
procedure SendData(Data: Pointer; Size: Cardinal);

Need help to define the Delphi/pascal record and add the byte values to it before sending.

Many thanks,

-B
