LoRa32 V3.2 - OLED Test source code?

#1

Dear all,
I am using the ESP-IDF version 5.4.1. with the Heltec LoRa32 V3.2.
I have tried several modifications to my code, but nothing shows on the OLED.
I have run the OLED Test downloaded from Heltec. That works fine. I have not managed to find the source code for that OLED Test. It would be highly appreciated getting a copy of the source code, such that I can check and modify my own code step by step.
Where can I find the source code (complete) for the OLED Test?

Regards,
jorsan

In the examples for the board - check Examples under the File menu in the Arduino IDE or look in the folders of the board support package.

^^ they are all in Arduino, not in ESP-IDF

The question was “Where can I find the source code (complete) for the OLED Test?”

Porting issues are implied and up to the OP.

Otherwise the answer is “There is no OLED test source code available for ESP-IDF”

Just providing some hints :wink:

Sorry, thought you thought I’d missed the ESP-IDF bit - too many thoughts, time for :wine_glass::bread::cut_of_meat:

Even in Arduino they would be useful. The essential is that the code is tested.

I have found some code on GitHub without identifying any real difference to my code. Initialization seems to be done in several different ways, timing i.e. delay between commands is not addressed. Shall there be a delay?

Dear nmcc,

Thank you for replying to my cry for help. Tested and proven to work code for Arduino is helpful, but raw C code using ESP-IDF is preferable.

I am still trying to get it to work, but I have no ideas left on what to try.

There isn’t any.

There is raw C++ code as described above, in the Arduino board package. The rest is up to you.
