Greetings,
I have a working ver5 uBitx using the "stock" display. I want to now use a 3.2" Nextion and CEC software. Could someone point me to the proper sketch. I am using what I believe to be the proper sketch and have set up ubitx.h like this:

Dennis,

Are you trying to use the KD8CEC software or just writing your own sketches for the Nextion.

In relationship to KD8CEC, Ian did some fancy footwork in his approach where he created buffers of commands/datas that he transferred back and forth between the Nextion and the Raduino. He did not use the standard Auduino library. On the Nextion side, this meant that he used timers and events (like a button press) to actually program that guy. BTW: Becareful of the Nextion code. Spaces matter! Especially in if/elseif statements.

Hi Mark,
I'm trying to use the CEC software.

Dennis,

You need to looks at the buffers that go back and forth between the Nextion and the Raduino. Quite frankly, I never really figured them out because there is limited comment in the code. So not going to be a lot of help here.

There are some basic definitions in the code (this is a command, this should be the last buffer sent, etc.) ? And then you are going to see how they are uninterpreted on the Nextion side. (you will need to download the Nextion editor) to see how the buffers are interpreted there.

Much different than the typical interaction between Nextion and a Auduino script.

Sorry, cannot be more help.

Mark

Here is the link to the KD8CEC github for version 1.2 that has support for the uBitx v5:


I believe that the Nextion tft files link is on this page:


Be sure to note the information in the v1.2 zip file that describes the different files in the archive.

Hope this helps

Thanks Evan,
I have downloaded the most current files (that you listed) and have uploaded first the sketches and then the hex files to see if there was any difference. The radio loses volume after these uploads and does not drive the Nextion. I really don't know what to investigate next. The radio works fine with the original software and display. BTW the last time I uploaded a hex file I had the original display plugged in and it worked just fine even though the file I uploaded was for the Nextion display. That really doesn't make sense to me.

Please be sure to use the correct hex file, there are a number of them.

Here is the FileNameInfo.txt listed.? Note that the hex file to use is dependent on the display that you will connect.? The the last part of the name indicates the display.? the file ending in _16P is the CEC software that will work with the original display.? The file for the Nextion displays end in _NX.? The _NX_S is for use with the I2C connected separate S meter.? Go to the Hamskey site to find out more.
