Flowcode Support Board

Hello,

I wanted to test Flowcode 9 (trial version) using Arduino Mega 23560 and a OLED Waveshare 1.3" with SH1106 in SPI mode.
It works fine with the Arduino IDE enviroment, but I wanted to test it also with Flowcode.
And it does not work. It has errors.
The compiler gives the the list of messages below.
Can you help to find the problem?

Hello geomanfred!

These tiny display doesn`t work in FC9 But fine in FC8 ?Have a look here:

viewtopic.php?f=3&t=790


Br Jorgen

Hello,

error: 'port' undeclared (first use in this function)

It sounds like your display component may have unconnected pins. Check the properties of the component on the panel.

I have tried various settings and in the end it worked for me.
I do not know what have I done to make it work. It could be pin remapping or Font setting, but it works now in SPI mode. One error that I remember was not setting the programming port on the project settings.
I have tried 2 different OLEDs with SH1106: one is Waveshare, which has SPI and I2C option and another one, no name, only I2C. Both worked, Waveshare in SPI and the other one on I2C.
The Waveshare worked in the past with I2C too, but now it does not work anymore with I2C, it works only with SPI. I do not know why. I have tried also with Arduino IDE, checked the pin mapping, the right address, I2C resistors pull-up and cannot be seen by the I2C scanner of Arduino, but in the past it worked. I do not why it does not work now anymore on I2C, but that is another story. FC9 works now in my case with these SH1106 OLEDs.

I have 2 more questions related with these OLEDs:
- Why I cannot print negative numbers on OLED display? Why I cannot see the “-” symbol?
- If I print a 2 digit or 3 digit number on the same X, Y location, then when it goes down. Lets’s say from 999 to 99 or to 9, then it remains on digit on display printed if I do not clear somehow that location. So I tried printing 3-4 empty spaces or tried ClearDisplay command.
In both cases, that digit blinks somehow, it is noticeable with the eyes that before is an empty space printed. It is disturbing.
I increased I2C to 1MHz and seems a bit better, but still observable.
With Arduino IDE I do not see anything, the text or numbers just appear on OLED on the same X,Y location even if print “ ” empty spaces before on the same X,Y location.
Attached is the test code.
How can we solve that problem?

Looking at this topic: viewtopic.php?f=3&t=1300
I tried to implement it usigíng TextField.
But I have the same problems: signed numbers, negative numbers are not printed and the location where is printed is blinking-like during the print moment.

Hello.
Within your loop, you are using Count using a variable.
That will always reset the variable to 0, so the count will override your variable value (-20 in your case) and start at 0.
Try the attached file, and see if that is what you are after.

Thank you Martin!
That solved indeed the negative numbers print problem.
How do we solve the 2nd problem?

Hello.
If not using the TextField component, you can ensure the unrequired digits are erased by printing a string instead of a print number.
Then use something like The spaces will overwrite the unwanted chars.
To convert a number to string you could either use or I have included both methods in the attached project.

Thank you very much Martin!
That solved indeed the "flickering" problem too and the OLED displays smooth the numbers.
