Problem Hydra and Display N18

Hello,
I use a Hydraboard and a Display N18. Now I want to write a text with the SimpleGraphics Class to the board. But I only get a very small Text which I can’t really read. And it appears twice on the Display. I use:

  • Firmware 4.3.6
  • Font NinaB
    I have the same problem when I want to draw a line for example. In this forum I read that there was or is a problem with the firmware. Is this right an when yes have I got a possibility for a workaround ?

A known issue with the current SDK. It’s been fixed in the next release

So I have installed the new Firmware Update on my Hydra, and the Display N18 work now. But it is very slow, is in this Update only implemented the workaround ? So I need a Display for this project, can anybody say if this will fixed in the near future ?

@ CS5798 - The N18 is not going to be anywhere near as fast as a native display. Depending on exactly what you are doing, a few frames per second is a reasonable expectation. How slow is it for you?

Hi John,
I have compare the speed with the Cerberus Board and it was much slower with the Hydra Board. Now I took the same program and change the
Board from Cerberus to Hydra. And it works pretty good now. I don’t know my mistake before. But I think it will work now. Anyhow thanks for your answer, I think it is Ok.
