Re: Solved: [ILI9341] flickering on drawstring on large characters.

Well, I didn't think that it could matter at that time. I know I am not a good electronics engineer :( .

Re: Solved: [ILI9341] flickering on drawstring on large characters.

Yes sorry! I mean milli Farad.

The power supply I am using to power the LCD is from the 5V Arduino Due.

Re: [ILI9341] flickering on drawstring on large characters.

I placed a 10 mF cap between the power lines and it seems to be fixed.
It seems to be that the steep current rising on the display is causing the display to flicker.

Solved: [ILI9341] flickering on drawstring on large characters.

Hello. I don't know if this the right place for this topic, so please place it in the correct board if it is not. I am working on a bluepill and on Sloeber. I have a 2.8 inches graphic LCD with the ILI9341 controller from buydisplay working with hardware SPI (the latest from Roger's repository). The...

If you are doing "Serious" development, then you should probably not use the Arduino API at all.
But then, unless you can find your libraries elsewhere, you will have to migrate them or re-write them.
And from what I can see, this can be cumbersome.

Which IDE for "Serious" development

Guys you seem to be experienced programmers, what IDE do you use? Arduino is way too poor to be used in serious development.

Re: Libmaple problem, program crashes with call to malloc.

The problem is the malloc, which crashes even without the KNX library, in a fresh, clean repository without me even adding the KNX library. The KNX library works nice when I compile with the Arduino IDE. Have you read my post? http://stm32duino.com/viewtopic.php?f=41&t=2434&start=50#p33027 I guess ...

Do the people at Sloeber provide support for all the various arduino cores it uses?
I don't know, I didn't ask anyone else, this forum is the first I am asking.

Re: Libmaple problem, program crashes with call to malloc.

Also, I just went through all the posts in this thread and I don't see anywhere that you have posted the changes you made to the KNX_Device or the CLI libraries. Please post those if you want help. It really doesn't matter about the KNX changes. The problem is the malloc, which crashes even without...

Re: Libmaple problem, program crashes with call to malloc.

What version of the core is the oldest you have tried? (like the date, or link on github) I don't know how to find the date. How can I find the oldest one? and can you post the simplest sketch that causes the crash for you and the board you select? Any sketch that uses a malloc will do, you may use...
