#8 DHT11 Data on DWIN HMI DISPLAY - 7" HD with RS232-TTL

[@techsigmarobots]

What is the 5" display about the connection of TX and RX

[@nagyCurtainsmotor]

Please explain how the control works from the screen, an external switch, and the output status

[@golantv273]

Can you show the value with 2digit decimal? I see this video the value are showing integer without decimal

[@tienat7403]

Hello teacher I hope you're very well. I need your help. I bouth this product FT232RNL USB TO RS232/485/422/TTL Interface Converter, Industrial Isolation. However, I haven't been able to connect this one with my arduino mega 2560. In my Arduino IDE Monitor always Serial.Available is false. I've connected the following schematic diagram for wiring. In fact, it is to cross-connect the TTL pins such as TXD-RXD RXD-TXD GND-GND: Can you help me please?

[@fredrikbergquist5734]

How would you compare this to Nextion? Is there some library?

[@fredrikbergquist5734]

Sorry I have asked the same question five months ago! Have finally ordered a few displays and will probably write a library for it.

[@arbjful]
