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.
Cheers,
Dan
