<blockquote data-quote="Herr R aus B" data-source="post: 219599" data-attributes="member: 62807">Custom chractersHere is what I've found out about the custom characters:<ul>
<li data-xf-list-type="ul">the VFD allows for defining eight custom characters</li>
<li data-xf-list-type="ul">each character is displayed in a matrix of eight rows and five columns</li>
<li data-xf-list-type="ul">to define one row, one byte is used</li>
<li data-xf-list-type="ul">within this byte the five lowest bits are used to switch on and off pixels</li>
</ul>The attached file dolby.txt (plain ascii text) which came with the MHC software contains the definition for the user defined display content as shown in the attached picture. Following the above statements, the given hex code values for the eight characters can be transformed to respective bitmaps:[CODE][FONT=&quot;Courier New&quot;]#1 #2 #3 #4 #5 #6 #7 #8&nbsp; |&nbsp; #1&nbsp; &nbsp; #2&nbsp; &nbsp; #3&nbsp; &nbsp; #4&nbsp; &nbsp; #5&nbsp; &nbsp; #6&nbsp; &nbsp; #7&nbsp; &nbsp; #800 1F 1F 07 1F 1F 1F 1F&nbsp; |&nbsp; ····· ●●●●● ●●●●● ··●●● ●●●●● ●●●●● ●●●●● ●●●●●00 13 19 04 00 00 00 01&nbsp; |&nbsp; ····· ●··●● ●●··● ··●·· ····· ····· ····· ····●00 11 11 05 13 14 08 15&nbsp; |&nbsp; ····· ●···● ●···● ··●·● ●··●● ●·●·· ·●··· ●·●·●00 11 11 05 0A 14 0E 09&nbsp; |&nbsp; ····· ●···● ●···● ··●·● ·●·●· ●·●·· ·●●●· ·●··●00 11 11 05 0A 14 0A 09&nbsp; |&nbsp; ····· ●···● ●···● ··●·● ·●·●· ●·●·· ·●·●· ·●··●00 11 11 05 13 17 0E 09&nbsp; |&nbsp; ····· ●···● ●···● ··●·● ●··●● ●·●●● ·●●●· ·●··●00 13 19 04 00 00 00 01&nbsp; |&nbsp; ····· ●··●● ●●··● ··●·● ····· ····· ····· ····●00 1F 1F 07 1F 1F 1F 1F&nbsp; |&nbsp; ····· ●●●●● ●●●●● ··●●● ●●●●● ●●●●● ●●●●● ●●●●●character definition&nbsp; &nbsp; &nbsp; &nbsp; character bitmap representation[/FONT][/CODE]And this matches exactly the special characters shown in the picture I took of the VFD.According to the COM port log your guess for the command was almost right.
