What am I gonna do now?

(yes I know, I 've ordered such an Oled screen but it'll take around 2 months to come to me)

EDIT: as I already mentioned, GPIO16 will be connected (using a diode) with RST. Maybe I could use the GPIO16 even if it's connected to RST?

If you upload with DIO mode then you can use GPIO10.

What is DIO mode? (ok, I found it here)
For the programming of the ESP I will use an FTDI:

Step 2: Circuit Time

Connect FTDI VCC to ESP8266 ESP-12E VCC and GPIO_2, RTS/CTS to CH_PD, DTR to GPIO_0, GND to GND and GPIO_15, TX to RX and RX to TX.

With the FTDI, can I program it in DIO mode?

- Mon Feb 18, 2019 12:42 pm #80641 Its an upload option so setting it depends on how you upload. If you use esptool.py then add the argument --flash_mode dio. If you use the Arduino IDE then when using the Board type Generic ESP8266 then you should see another option in the Tools menu 'Flash Mode' where you can select DIO.
