Nextion: failed initializing display

[oswatt55]

i got the issue below, can you help me? My project is in eclipse, I´m using nextion NX4832T035_011. In your exemple i get this In the terminal in the code of nextion.c

Sure! Could you please tell:

• What is the baud rate configured on your Nextion device? The log shows that the library is using 115200.
• Are you using the example code or a custom one? In case of a custom one, could you share it?
• Have you tried using a different library? If both fails, the wiring might be misconfigured.

[oswatt55]

Thanks. My baud rate is 115200. I´m using the exemple Not, i have only used your library

[gfurtadoalmeida]

Ok. I'll take a look at that after work. Unfortunately, I don't have a Nextion device anymore, so will test with the simulator, using your NX4832T035_011.

[oswatt55]

Thank you very much.

It already works, I needed to specify in the nextion editor the baud rate baude=115200, but now I have these errors, I'll keep checking the causes

Nice! The Installation Wiki was updated with this information. What really need be done, in the future, is the implementation of an automatic baud rate detection.

I can't reproduce the sync error error. I've just cloned the repo, copied the example code to main.c and flashed/ran. Everything worked fine.

What values are being set on CONFIG_NEX_UART_* params? The CONFIG_NEX_UART_MUTEX_WAIT_TIME_MS parameter is used as a timeout when trying to acquire a mutex. A very low value could cause this problem.

What is your ESP-IDF version?

[oswatt55]

My params in the file config.h ESP-IDF version 4.3

Could you clone it again, copy the example code to main.c, flash and run? I've tried again but could not reproduce the problem.

[oswatt55]

okey, It already works, thanks Gabriel

[gfurtadoalmeida]

Nice! What was the problem?

[oswatt55]

my code had errors. I came back again with your example and it works correctly

[oswatt55]

Do you have an example of the nextion_component_set_property_text function? I am confused with "property_name"

[gfurtadoalmeida]

Nice! I do not have an official example, but you can look at this test.

The function nextion_component_set_property_text sets a component property to the text value passed on the text parameter. The property_name is the name of the property you want to set. For this function, the property being set must accept text.

Let's say you have a textbox name "t0" and you want to set its text to "Hello World", in this case the property_name would be "txt". You can get the property name in the component's property tab (example below). Every component has different properties.

thanks for your explanation and example, my project works correctly, thank you very much

Happy to help!
