also You mentioned using ssh to connect. If you wanted VNC: When starting up bookworm I saw vnc viewers failed.
The temporary fix, raspi-config advanced Wayland, set x11.
sudo nano .config/wayvnc/config
address=0.0.0.0
enable_auth=false
enable_pam=true
private_key_file=/home/pi/.config/wayvnc/key.pem
certificate_file=/home/pi/.config/wayvnc/cert.pem
Then realVNC functioned.

Looking at the Pigpio issues, it will not work on P5. There is no detail on when the Pigpio might be modified. There are comments stating this appears to be a large undertaking and there is no firm commitment on who/when. Also, the linuxFS on P5 is not clearly understood. As more of us actually have a P5 in our hands we can validate what does and does not function and then size the work.

Thanks for the reply - this is a RPi 4.

Oh man. I saw bookworm and jumped to p5. U clearly said p4. I do have a bookworm image waiting for a p5. I will load it into a p4 and try your code. What is the model of the 16x2 you are using and the version of pi4j ?

It's out of a FREENOVE starter kit. The tutorial docs describe it:
"The serial-to-parallel IC chip used in this module is PCF8574T (PCF8574AT), and its default I2C address is
0x27(0x3F). You can also view the RPI bus on your I2C device address through command "i2cdetect -y 1"
(refer to the "configuration I2C" section below).

In /dev

Pi4j version - I cloned the main branch of the component project.
https://github.com/Pi4J/pi4j-example-components
<pi4j.version>2.4.0</pi4j.version>

Thanks again @taartspi. I spent some time reading the manual and discovered that I needed to enable the i2c interface in raspi config. The listing of the i2c bus in /dev threw me off and I thought it was pre-enabled.

User error - needed to read the manual.

Evening. Glad you got it going. Take care
