I haven't run trials, but one of these medoti should work.

> @tistructor according to your code it looks like it pulses not 2Hz, but 0.5Hz (full cycle in 2 seconds). So what is the correct value? Yes, that's correct, I...

I checked all the problems with rp2040 but there is nothing about the fact that I2C software doesn't work. I tried in every possible way but the display remains off....

I could try powering the display with 5V as it accepts this power while keeping the data level at 3.3V. But first I'll do a test with 5V arduino and...

I scanned with software and found 2 addresses: Device found at 0x79 Device found at 0x7A However, with the I2C Hw test I only find one address and it is...

I tried changing gpio for i2c software and the scan results in the same 2 addresses.
