I am not an expert, but I can use correctly Arduino IDE.
I have bought ESP01 without firmware.
I need to load software to drive Oled 128x32, and displayed IP adresse, for reflash with ESP01_OTA (across platform IO)
Impossible to find INO source.
Thank you for your help.
Regards

These come with either a I2C or SPI interface.

The ESP-01 is not a great module as it has very limited IO. It would be better to use either a ESP-12F module or a Wemos D1 mini Pro. The latter makes development easy as it can just be connected to your development system by USB. If you must use the ESP01 then that can work with a I2C display as that only needs 2 GPIO pins.

You then need to use a library to drive the display e.g. Adafruit SSD1306. Once you have installed that in your development system then there are example .ino files included which will give you a starting point.

- Tue Mar 15, 2022 4:58 pm #93956 Thank you I am in progress. I have succeeded to load a wifi server. Now my ESP01 is connected to my box at 192.168.1.100.
Now I would like upload my application to drive my OLED screen witch SDD1306. The code is ready for this chip.
I use for this, Visual studio and plateformIO, and I compile with ESP_1m-ota to compile and upload.
Compilation is OK, but I have error message.

The terminal process "platformio 'run', '--target', 'upload', '--environment', 'esp01_1m_ota'" terminated with exit code: 1.

I am not sure param in plattformio.ini:

Do you have an ideas ??? thank you very much
