Re: Help with VK204-25 I2C communication
Hi, I tried changing the pins already. I also tried both on Arduino Diecimila's A4 and A5 pins and on Arduino Mega's SDA and SCL dedicated pins. Regarding the Oscilloscope and serial communication, sadly I'm about to move to another country and most of my staff is already there, so I don't have an O...

Hi Dan, yeah of course, silly me I should've imagined the H was there for that reason. Regarding the jumpers, it's easier for me to post a pic since I'm probably short of terms/knowledge to answer correctly, I'm sorry but I'm just starting out... https://i.ibb.co/Zxtq51j/5f322208-34f3-48f7-8ec1-6d26...

Re: Help with VK204-25 I2C communication
Hi Dan, thank you for your reply! First of all, the IDE sent me an error message for the address 0x28H, so I used a binary to hexadecimal converter and it seems that the new address is actually 0x28. I updated the code, but I still get no results on the lcd, just the bottom-right corner blinking. I ...

I think the problem is that it is not set to i2c mode, since I know for sure that it was used through RS-232. I tried checking in the manual...
