Bars and large digits?

relix · Post by **relix** » Wed Jan 02, 2002 12:11 pm

I've got a problem with my LK204-25PC here:
- vertical bars can only be 1, 2, 3 or 4 blocks high, there is no differince betwee for example 26 and 28 pixels.

- large digits don't show up right, all I see are, on the place of the large digit, black blocks!

Hope someone can solve it!

I have the same problem with large digits. Relix, if you solve this please tell me how you did it.

tell me, since you both are writing your own software here, have you tried to make large digits in your program? Give me more details here...

so, after Henry gave me a little test app the large digits work. The bars not yet (and I'm not smoking anything here and not telling you

). I'll try to complete the large digits code in my "lcd-engine" as soon as possible and then I'll post here what I have found.

I have a program that you can use to test large digits. It does not specifically work for MO units (mainly because the only serial LCDs I have used are Wirz) but it will work for them under LCDriver. You can download them here: http://www.geocities.com/special_4k4
Goto the LCD applications link and download LCDTimeDR1r8.zip
It requires LCDriver, but it is a nice example of large digits. Another example is LCDStatScrollDR1r3.zip which is also in the files directory.

OK, I have begun to dig deeper here and pulled another display off the line... I'm encountering some kind of problem as well here, under Alpha Demo only the first digit will appear form the large digits... I will write a program to test it better...

And specialk, our displays have built in large digits, so you don't have to make them in the software, just call them, LCDriver re-creates them from scratch because I believe some of the other manufacturers didn't have them.

I've seen the information that the MO LCDs have a large digits control or mode of some sort. When you said "have you tried to make large digits in your program?" I was thinking, hey, I did that! The large digits in my program are not made by LCDriver, the program makes them and renders the display line by line on the fly (this can be seen with my LCDStatScroll program). LCDriver is just a simple, universal control panel that allows applications to be made and distributed to a large audience of people without having to worry about proprietary configuarations.

here is a example on how to display large digits...

0xFE
0x6E //this turn large digits on

0xFE
0x23 // or '#'
1 // column ex 1
5 // this displays the #5 digit and so on...

We went through the trouble of designing large digits, I belive the head engineer spent some time to make the large digits really nice... I'll post a pic later... So the large digits from company to company are different (that's if they have them).

So instead of making them as you said, all you have to do is call on them in the software all ready.

That seems like a VERY easy way to deal with things. I know it took me quite a long time to get all of the information in and working for my LCDtime program and it took even more time to put in all of the large alpha-numeric data for my LCDStatScroll program. The only problem with it in terms of having a number of people use your software is that because it does use proprietary codes, people who are using C**********z or backpack (Wirz, Seetron, etc.) serial LCDs will not be able to run the software. While it was much more difficult to program in all of the information for each number and letter, in the long run, by putting it in an LCDriver application, now anyone who has an LCDriver compatible LCD can use the big font I made

Yes it's easy, and that's the whole idea. Most of our market is OEM sales and by making a easy solution for them makes them happy. This way they don't have to re-invent the wheel every time they make a new application. So yes, there is a problem with cross LCD compatibality, but like I said, most of our market is OEM who will not be swapping in our LCDs and other LCDs. And yes, you did make a nice font...
