Bad graphics using ESP32-24325028

[fcknzs-love]

After the first set up flawlessly, I got a second CYD. Unfortunately, with this one I have some display/graphics issues. The colors seem to be inverted, meaning black is white, white is black, yellow is blue and blue is orange. I also believe the image is slightly blurred.

And after all, this one doesn't start mining... CYD is from AliExpress (the cheepest, I could find...). Flashing only worked with https://flasher.bitronics.store . With ESP tool I got an MD5 mismatch..

Hello

Regarding the messed up colors...

Seems the firmware on https://flasher.bitronics.store/ is not optimized for the ESP32 2432S028 with two USB connectors. I have that one as well.

Try flashing with Platformio and select "ESP32_2432S028_2USB" as env.

Hello. I have no idea how to work with Platformio.... Is there anyway to have the BIN file for this board and upload the firmware easier for a newbie here? Thank you. :)

It should be pretty easy to work with PlatformIO. Follow this guide: https://platformio.org/install/ide?install=vscode

Then install Git command line tool. Not sure which one to advice. I am using https://git-scm.com/download/win under Windows.

Clone NerdMiner project git clone https://github.com/BitMaker-hub/NerdMiner_v2.git

Open cloned folder in VScode.

Build with "button" at the bottom of page (choose target first - also on bottom of the page).

Thank you so much, i think i got it. :)

This guide is not applicable to this specific device. RST button does reset of the device.

BOOT button works like on one button device:

(I have tried just single, double and tripple click)

More to this: you can somehow press screen to switch screens (if you have touch version). Not sure how exactly shall this work. It is not very reliable to me.

@djcasper1975 Thanks, the files fixed my screen issues. What is the AP password ?
MineYourCoins does not work.

What board did you choose when flashing? Mine is a single usb. I chose the one ending in ‘R’ but screen doesnt work.

[fluxres]

I ended up programming through platform IO. I have the two USB variant and chose that in the build environment. It worked a treat, have programmed 4 now with no issues.

[Russty123]

Yeah im on the platformio. Ive tried the 2 usb build and the and the one ending in ‘r’ mine is just single usb and the board is esp32-2432s028. When i load the 2usb build colour is pale and the image is off (see pic) and when i load the ‘r’ build screen is small. So which one build was the first one you tried before platformio? i might have to start another thread as another issue?

[Russty123]

Screen alignment is good when mining but colours are off. Or is yours still white? Blue and orange like this? I have other miners that look better than this.

[fluxres]

First time I used the "r" variant. I had the same issues that are shown in your images. The first time I used the online microminers flash tool as per git. It's super easy. Have you tried using that ? It has worked fine for my "r" variant boards.

[Russty123]

Ok i’ll give that a flash tool ago. If it fails i found this edit of the code that i will try, its inverted colours. Thanks for your time and help

[IAmSixNine]

Thank You. I have the 2 usb one and had off colors. the zip file allowed me to fix this issue. Im not a programmer but trying to learn. So thank you for posting the files I needed.

[mrijkhals]

I had this problem with some Arduino oled projects to, nothing to do with nerdminer. The screens were not RGB but RBG so i had to change the library in order to get it work. Maybe this fixed the issue over here to.... Anyway the new flash file worked fine thank you
