ATS-Mini ESP32 / Si4732. Inversion colors will appear on the display screen.

[RadioHam25]

Hello! After compiling the project and writing the project to the ESP32S3 controller, the inversion colors will appear on the display screen.

I don't understand the reason?

If I program the *.bin files, then everything is fine. The display color is correct.

Hi!

At first glance, it seems like a problem with your compilation environment. What software are you using to compile it?

I can't compile it again to test because my radio is currently without a working screen (I accidentally broke it). I will confirm to you once I get it working again in one to two weeks as a new unit arrives.

In the meanwhile, you can test as follows:

1- Make sure you're using a clean compiling path by creating a new folder.
2- Use the files downloaded from the feature-fastAutoscan branch, by clicking the "code" green button and downloading them as a zip file:

Hello! I've checked everything. Everything is right. I downloaded the code archive, unzipped the code, and installed the necessary libraries. I compiled the sketch in the Arduino v2 environment.3.6. The sketch compilation was completed successfully.

After compiling the sketch, binary files were obtained. I used them to program a radio receiver. I used the program "ESPTool".

The radio was programmed and restarted and started working. everything is OK. But the display color is inverted. All preset themes are inverted. Why this is so, ina is not yet clear.

Then, I downloaded your compiled project with binary files. I recorded it on the radio. The receiver began to display the correct colors on the display.

It's possible that this problem exists not only for me, but also for other users.
Is it possible from menu -> settings to add the display color inversion function?
Display inverting "ON"
Display inverting "OFF"
It would be useful.
It would be nice to make a Si4732 variable capacitor in the menu -> settings.
The capacitor is "ON"
The capacitor is "OFF"
Now it is disabled in the project.

Hi! My replacement V2 ATS-MINI unit arrived yesterday.

Today I downloaded a fresh copy of the feature-fastAutoscan branch and extracted it on a fresh folder to make sure nothing on my files is different.

Result: No problems. Colors on screen are OK and every theme work as expected.

I did notice based on your screenshots that you're using a weird board to compile. This can be the issue.

Try with this board:

Hi, Humberto! I followed your advice. It worked out. You're a professional! The compilation was successful, and the colors are correct.

I was curious about the controller installed in my radio, so I disassembled it. It turned out that my radio had an ESP32-S3-N16R8 controller.

I found this controller in the list, and it also worked well for compiling the sketch.

With your help, I was able to resolve the issue with the inverted colors on the display.
But I still have one question.
Can you make a switchable variable capacitor in the menu -> settings?
The capacitor is on.
The capacitor is off.
Now, for experiments, I need to reprogram the radio to turn the variable capacitor on or off.

Hello!
In the new version of Fast Autoscan second release v0.2, Bluetooth is activated. What application can I use and what features does it offer?

Hello! In the new version of Fast Autoscan second release v0.2, Bluetooth is activated. What application can I use and what features does it offer?

Hi! The activation of bluetooth was derived from the upstream (original project by Max Arnold and others). As far as I know, they plan to add remote control via a protocol. For the moment, nothing is implemented, it's just on as an experimental measure.

Make sure to erase the flash memory with the new builds, as there have been changes on the settings storage order, and unexpected behavior can occur (maybe that's why you see enabled bluetooth)

Everything is clear. Thank you for your reply.

Hello! I like the firmware "Fast Autoscan second release" v0.2. Could you add the ETM (Easy Tuning Mode) function to the firmware, like in Tecsun. It allows you to automatically search and store radio station frequencies in memory. This is convenient and will extend the life of the encoder.
