Hi

I try to create a procect with an Arduino an a KS0108 display. The display show some strange sign. I have checked the wiring many time and change the display but same result The sign is moving so something happend.

Am I doing something wrong please?

Hello.
I have checked your project on a Uno and the KS0108 is working as expected. Since it works on the Uno, there is no reason for it no to work on the nano.
The issue you see with the display is either a wrong data connection or Open/Short.
With the power removed it's worth checking each pin of the display is connected to the correct pin of the nano using a DMM

If you run a full database update and make sure uart cal is updated, the PZEM component wrapper will look a lot better.

Hi Martin!

Many thank´s for wiring up and testing my program At least I am glad it work by you, then I know I do something wrong.

It is strange, because I have checked all connection several time and also a new display. I test with a LCD display it work and your PZEM component also, perfect.

I am always full update with FC.

I will check again, if I not manage I will test on an Uno.

You hear, thank´s

Hi Martin!

You were right Martin. Two of these cheap jumper wire have bad connection, after replacing them, the display works perfectly.

Once again, thank you very much for your help

Hi Jorgen.
I'm glad you managed to resolve the issue, well done.
I have had O/C jumper wires before, So I feel the pain.
Thanks for keeping us updated.
