hello

i tried uploading via your method, but now i have the following error message

at least no software errors now. check hardware.

sivansriman · June 4, 2022, 5:40pm

okay will do. anything specific to look out on? all connections are verified

kolaha · June 4, 2022, 5:43pm

show your setup

sivansriman · June 4, 2022, 5:45pm

this is it. i have verified the connections too

sivansriman · June 4, 2022, 5:46pm

my question is, the basic blink code uploads and works without any issue but this does not. is there something im missing out on?

kolaha · June 4, 2022, 5:47pm

disconnect display while upload

sivansriman · June 4, 2022, 5:48pm

same error shows up again

kolaha · June 4, 2022, 5:53pm

after blink sketch you change something. i think some wires missing or have not good contact

sivansriman · June 4, 2022, 5:59pm

i verified every connection yet again and everything is alright. i retried the blink code and that uploads without any flaw.

sivansriman · June 4, 2022, 6:07pm

i think this error pops up the moment i include the wire.h library to the code. does that help?

kolaha · June 4, 2022, 6:13pm

simple including bring no change. how it used is important.

sivansriman · June 4, 2022, 6:18pm

yes

And i managed to figure it out. burning the bootloader before every upload helped
