Necroing this thread… Does anyone know if the Waveshare LCD1602 RGB is compatible with the HD44780 instruction set? Including display on initialisation? I have it working on my raspberry pi 4b using the demo python code, however when I try using it with a project that assumes a HD44780 display, it doesn’t turn on. Pretty confident that I have set the address correctly, as using i2cdetect, I can see the I2C address is 0x3e, which aligns with the python code 0x7c\>\>1. The project is [GitHub - probonopd/MiniDexed: Dexed FM synthesizer similar to 8x DX7 (TX816/TX802) running on a bare metal Raspberry Pi (without a Linux kernel or operating system)](https://github.com/probonopd/MiniDexed). Cheers, Dan ---

Hi Daniel A couple of years ago I purchased a Waveshare 1602 display (Waveshare number appears to be 19537) which is I think the RGB backlight version of this one in question. I was attempting to use the supposed Waveshare library as on their web site. I played with this using an Arduino R3 for some days and could get nothing to display properly. Just a load of rubbish with a included just the character blocks described above. I tried printing using a couple of different ASCI codes but to no avail It did come up with some strange characters which I could not identify or correlate with the ASCI codes I knew about. It went back into its box and has been there ever since. One contributor suggested I try the DfRobot library but I did not get around to it. I opted for a 1602 display with the little I2C adaptor board mounted on the back. Works fine. Cheers Bob ---

Hi Dan, Unfortunately the instruction sets for the displays seem incompatible, but if you’re keen on trying to remix it to use the Waveshare display the userinterface file’s are ready for changing 😃[MiniDexed/src/userinterface.cpp at main · probonopd/MiniDexed · GitHub](https://github.com/probonopd/MiniDexed/blob/main/src/userinterface.cpp) GPT would help a ton here! We do offer the backpacks used in the project as well: [I2C LCD Backpack for 1602 to 2004 LCDs | 018-LCD1602-I2C | Core Electronics Australia](https://core-electronics.com.au/i2c-lcd-backpack-for-1602-to-2004-lcds.html) Liam
