It has been a year or so since I was used a ESP-01, but isn't GPIO2 used for booting the device.

I think so. I have not taken any steps to actively make it work like setting it high, apart from following online guides.

Good day! I have successfully loaded uP 1.19 on an esp01 and can get it to write text to an OLED and blink and LED if I bread board them separately: Esp-01 to OLED on bread board https://www.instructables.com/I2C-With-the-ESP8266-01-Exploring-ESP8266Part-1/ Connect USB / FTDI programmer to esp-01 an...

This seems pretty awesome. It seems like this file is the key: https://micropython.org/resources/firmw ... ffda17.uf2 HermannSW was saying that this firmware fixed the issue (it's probably the first nightly build after that feature was added), but any _later_ version will work. Just use the 1.19.1 ...

* "74880 bps" in gtkterm as well as Thonny. Once MicroPython is running it should be 115200. Thank you for your reply Jimmo. I reflashed w/a data cable I thought I actually used to flash before (I suppose I should have used a leather bound journal entry with proper dated entries). I am second guess...

Howdy All This seems pretty awesome. It seems like this file is the key: https://micropython.org/resources/firmware/rp2-pico-20210413-unstable-v1.14-159-g1a2ffda17.uf2 I got 404 Not Found trying. The postings here literally seems like the best option for uP http gets/etc.. Anyway, I was thinking the...

Good day All I have a Wemos NODEMCU ESP8266 (ESP-12F w/0.96 OLED) I can flash it with esp8266-20220617-v1.19.1.bin or esp8266-20220618-v1.19.1.bin just fine. But after booting I see: 8266.jpg It is not streaming text. Just seems to be 'static'. Other posts suggest to use different flash modes. I thi...

I received a reply from tech support. In short was using the wrong driver, the right one worked (color): The ssd1306 code runs on MakePython ESP32 not ESP32 Color LCD https://www.makerfabs.com/makepython-esp32.html You can get the code runs on ESP32 Color LCD from our wiki: https://www.makerfabs.com...

Hi. I have basically the same sort of out of the box experience. I got the makePython ESP32 Development Kit oled because the screen looks beautiful. I also could not get a prompt at first. I needed to flash to the latest version of Micropython. Now I can and I can use the wifi, BUT I cannot use the ...

LCDs typically run at 5V. Do you run them at 5V, and do you have the contrast set? Right. Thanks Robert. I should have mentioned. The Nodemcu is plugged into my USB, supplying 5V, and the Nodemcu is connected to LCD's VCC via it's VIN pin. My understanding is the pin marked as VIN provides 5V as pe...
