I need to use Visual basic to acquire some data through the serial port, store it etc. As I am just getting acquainted with VB6 I need some help.

My Controller board (8 bit micro) sends out serial data 3 bytes at a time ( a packet). The data are typically binary bytes and can have values from 0 to 255. To signal the start of a set of bytes the CTS line is given a high. The data set is sent at intervals of 35 milliseconds. I need to receive the data and store them into 3 different arrays so that at the end of a given period of time we have the three arrays with Bytes 1, Bytes 2 and Bytes 3 respectively.

I have done some study of the MSCOMM control but I am confused about what data types to use, how to buffer the data into appropriate arrays etc. I cannot do this in polled mode also.

Looking forward for help in this regard

Thanks

do check the tutorial for more information regarding visual basic programming using the MSComm object. also check the following thread:

P.S. hope u have send the data to the PC in ASCII format.

good luck. ]]> contact@nospam.com (Ajay Bhargav) Sun, 03 Aug 2008 07:15:38 -0700 http://www.8051projects.net/forum-t11339.html http://www.8051projects.net/forum-t11339.html contact@nospam.com (Ajay Bhargav) Sun, 03 Aug 2008 21:44:12 -0700 http://www.8051projects.net/forum-t11339.html http://www.8051projects.net/forum-t11339.html first just try sending the data to the PC using the MAX232 and check if u are getting the bytes at the PC using hyperterminal before going in for a VB interface. that would ensure that ur hardware and the uC code is correct.
