Zigbee network can already be on the serial port assistant communication, the sender sends each time a data, the receiver using Delphi do a receiving interface, the interface and can display the data in the memo has been completed, the memo each data line shows such as: 12
13 and so on, now want to have an odd number of rows value as voltage value displayed in the DBGrid, the even line values as DBGrid, according to the current value according to the received value generation dynamic voltage - current curve, the function of this program the how to write, this problem has been with me for a long time, ask the master to give directions! Thank you very much!!!!!

CodePudding user response:

Why use Memo!
Can't receive the value directly into the DataSet?
Graph can directly use the DB control connection data sources to the DataSet can be!

CodePudding user response:

The graph, it is ok to use TChart controls set properties,
Receiving data, best can be directly inserted into the database,

CodePudding user response:

Can not get the number of rows, memo to judge yourself

CodePudding user response:

Lu too sticky beaming

UP UP day day UP

CodePudding user response:

1. In the memo shows at the same time, to the table in the
2. Dbchart==& gt; Fast line

CodePudding user response:

If sending data rate is not the bottleneck, suggested sending ASCII string
Easy to check, verify, and not a wrong all wrong behind
Such as:
V=12.34
I=23.45
V=12.25
I=23.39
.

CodePudding user response:

I think LZ idea is wrong, just received data unpack, put the GRID display is not better? In front of the database, can use StringGrid display

CodePudding user response:

This kind of easy speed to keep up with,
