Re: machine.UART how to skip read?
UART.any() will return how many bytes are waiting in the queue or 0 if nothing and it is non blocking

Re: Not getting REPL after uploaded a library
You probably have a main.py that crashes the firmware. You should have a look here

Re: PWM limited to 255
You can left shift the value in order to switch from 8 to 16 bits.
Say you have 0 ≤ value ≤ 255
if you make
value = value << 8
You will have 0 ≤ value ≤ 65280
Maybe you can elaborate on what your problem really is.

Re: Cannot get access to /dev/ttyACM0
Are you sure Thonny is up to date? The release on the repo is 3.2.7, currently on thonny.org the release is 3.3.6.
Maybe you can load the last release at thonny.org

Re: main.py isn't running when Pico connected to external power
Can you post your main.py?
Are you sure, you are not missing any import or pin setting in your software?

Re: LCD1602 error I2C
Default address on similar I2C adapter (using a PCF8574) is 0x27 (39 decimal) which is compliant with the address the scanner returned.

Re: LCD1602 error I2C
In the first program, you try to write at address 114. If you have no I2C slave at that address you have no acknowledge and the write probably crashes.
In the second program the scan tells you that you have a slave at address 39 which maybe is an I2C expander.

Re: SPI on the Pico: has anyone made it work?
I have adapted a driver for an oled display using sh1122. It is using SPI. Code is here viewtopic.php?f=14&t=9769 it runs without any problem on my Pico.

Re: Running two Pico's from the same computer.
Well, if you plug a second Pico to your computer it will appear as ttyACM1. This is an automatic feature the new device is created when the device is plugged in. You can verify with a ls /dev/tty* in a terminal After you plug the first Pico, ttyACM0 will be listed After you plug the second one, ttyA...
