Trying to get this to work with Spotpear LCD

This is my lcd http://www.spotpear.com/index.php/index/study/detail/id/77.html

Type of Raspberry Pi

Raspberry Pi 3A

Linux Kernel version

Linux raspberrypi 5.4.79-v7+ #1373 SMP Mon Nov 23 13:22:33 GMT 2020 armv7l GNU/Linux

Expected behaviour

I expect a 3d box

Actual behaviour

Trying to get the display to work with the correct driver If I try and run 3d_box.py I get the following error message

3d_box.py: error: I2C device not found on address: 0x3C

This is no surprise as i2cdetect 1

Does not report anything, I get 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: – – – – – – – – – – – – – 10: – – – – – – – – – – – – – – – – 20: – – – – – – – – – – – – – – – – 30: – – – – – – – – – – – – – – – – 40: – – – – – – – – – – – – – – – – 50: – – – – – – – – – – – – – – – – 60: – – – – – – – – – – – – – – – –

Does anyone have any pointers please?

first quick note - your LCD is not I2C, is SPI, so you need to let the driver know how to correctly reach your display - through the correct SPI port, using the right SPI settings and right GPIO pins. You should be able to get all of these parameters from the example code they’re providing.

happy to hear that! It’s not even clear to me that you need the SPI and GPIO parameters, I’d bet they’re just unused, try removing them and my hunch is that it will work just as well.
