Re: Stretch vs Jesse

Stretch is the current supported OS. The lite version is text command line only.... No GUI.... No desktop. I would recommend the Stretch with Desktop. It is a much smaller download, (1.0 vs 1.8GB), than the full version as it does not have games and some large educational software packages. There is...

Put the SD card back in your PC or Mac. look for config.txt and edit it back to the default settings. Be sure to ignore any prompts to scan, format or initialize the SD card.

Re: I do not walk the mouse correctly with touch screen in the Raspberry Pi 3

What do you mean by "did not walk the mouse correctly"? The OP is probably referring to touch screen calibration. Raspbian default has a very basic single touch driver which just moves the mouse pointer to the touch point. I tried using my 23" touch screen with USB touch interface. The calibration ...

Is your WIFI 2.4GHz? The built in WIFI of the RPi Zero W does not do 5GHz.

Re: Serial port/UART on RPi OR RPi3 connection issues

Yes this is just a simple loopback test at the module 9 pin RS232 connector. Verify that you are connecting pin 2 & 3. It is easy to get the wrong pins. The pin numbers are usually molded into the plastic next to the pins. Try swapping TX and RX wires at the RPi -OR- at the module end. With the modu...

Re: Serial port/UART on RPi OR RPi3 connection issues

The MAX3232 adapter must be powered with 3V3 not 5V.
There must be a ground wired from RPi to adapter.

Attach the MAX3232 adapter to the RPi and now do a 'loopback' test by shorting pins 2 & 3 of the DE9 connector.
