Re: Make EVE2-29A look like a green crt display

Hi Bob, I've done some testing here, and unfortunately, I wasn't able to display your image successfully in a relatively quick manner. I can display images, but they take a little bit of time to load from the SD card. I'll continue testing, but I should let you know that I'll be out of the office be...

Re: Upgrading ELK204-7T firmware

Hi Foobar, Welcome to the Forums! Yes, you are correct. The ELK204-7T-1U is based on our LK204-7T-1U display. As you have mentioned, there seem to be a few errors in the display's description. I apologize for any inconvenience this has caused you. We are working to correct these errors on our websit...

Re: Boot screen with company logo?

No Worries Mascenzi. Also, just a heads up, we have a program called BootLogo that can help you design your logo. In addition, the program allows you to upload your logo along with your custom characters directly to the display from your PC. The program should make it a easier to design your custom ...

Re: Boot screen with company logo?

Hi Mascenzi, There are only 8 custom characters available on the OK204. You could try to find a way to use the same custom characters for different parts of your Logo eg. you could modify some of the custom characters used in the 'I' so that they can be reused in the 'P'. That would reduce the amoun...

Re: C++ using customer characters? OK204-25-USB

Hi Mascenzi,

You should be able to send either of the following:

WriteFile(my_port,"\0x00", 1, &bytes_written, NULL);

or

unsigned char b = 0x00;
WriteFile(my_port,&b, 1, &bytes_written, NULL);

No command will be needed to draw the custom character on the screen.

Cheers,
Daniel

Re: C++ using customer characters? OK204-25-USB

Hi mascenzi, It won't be necessary for you to save your custom characters in order to use them. Once a character is created, you can draw it on screen it by sending the assigned custom character ID to the display. I have a pseudo code example demonstrating how to use custom characters below: ClearSc...

Re: C++ OK204-25-USB writing text issue

Hi mascenci, Welcome to the forums! I've taken a look at your first photo (helloworldchar.jpg) and it looks like your string's NULL terminator (0x00) is also being sent and displayed on screen. Sending the Hello World string without the following NULL terminator should get rid of that extraneous cha...

Re: require code for designing on EVE2-70A

Hi Madhusudan.Jadhav,

Have you modified the EVE Know code at all to properly interface with your Infineon processor?

The EVE Knob Example was designed to be used with an Arduino, so modifications may need to be made in order for it to work properly with your host.

Cheers,
Daniel
