Soldered Support:

Which Dasduino board are you using? Also, can you copy the console output that appears when you attempt to upload to the board and share it?

Original message (Croatian)

Možete li navesti koju Croduino pločicu koristite? Također, možete li kopirati ispis iz konzole koji vam se prikaže pri pokušaju uploadanja na pločicu i poslati ga?

Customer:

I wrote it incorrectly - I’m working on Dasduino CORE. There’s no feedback output; it appears the program is loaded but nothing shows on the screen. I’ve also adjusted the contrast. What settings must I have in the Arduino IDE for Dasduino? I downloaded the library for all Dasduino boards and for the display as well as for all other sensors.

Krivo sam napisao, radim na Dasduino CORE. Nemam povratni izlaz, ispada kao da je program ucitan ali mi na ekranu ne pokazuje nista. Promijenio sam i kontrast. Koje postave moram imati u ARDUINU IDE za Dasduino? Skinuo sam libary za sva dasduina i za ekran
kao i za sve ostale senzore

Soldered Support:

Can you attach the Arduino sketch you’re using to drive the mentioned display and which model is that display? From what I understand, the code successfully transfers to Dasduino CORE, which suggests the problem is likely on the software side.

Original message (Croatian)

Možete li priložiti arduino sketch koji koristite za pogon spomenutog ekrana te koji je model tog ekrana? Koliko shvaćam kod se uspješno prenese na Dasduino CORE, što nam govori da je problem vjerojatno sa softverske strane.
