Portenta H7 with Nextion Serial Strings Read

Using Arduino Programming Questions
1

Hello everyone, I need some help.

I have a Portenta H7 and a Nextion display and would like to read serial strings and also output texts on the display.

The strange thing is when I connect it to an Arduino Mega via interface 0.1 then it works.

I would like to use UART 1 or UART 2 with the Portenta.

Can someone maybe show me a code how to read continuously without errors? I've never seen that before.

So i will paid via Paypal if you help me

Thank you

Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Please create one topic only for your question and choose the forum category carefully. If you have multiple questions about the same project then please ask your questions in the one topic as the answers to one question provide useful context for the others, and also you won’t have to keep explaining your project repeatedly.

Repeated duplicate posting could result in a temporary or permanent ban from the forum.
