Using Stretch, I was able to access the RPI2 file system from my Mac by entering a user ID and password. I upgraded to Buster, I can use a VPN, I can use SSH, but I no longer can use the Mac Finder to mount a directory on my Mac (using the Finder / Go to Server command). When I enter in a user and p...

I get your point that mixing spidev and gpiozero could cause problems. The only reason I included spidev is that it provides a way to set the SPI clock speed. I've retested after removing spidev and using the following: pot = MCP3002(channel=0, device=1) and it works perfectly. It appears the gpioze...

I am working with Python 3.5 with gpiozero 1.5.0. I have successfully used the following script: from gpiozero import MCP3002 from time import sleep import spidev spi_max_speed = 50000 # 1 MHz for SPI spi = spidev.SpiDev() spi.open(0, 0) spi.max_speed_hz = spi_max_speed while True: #read channel 0 o...

Having read the comments, I made new attempts today. 1. Previously I had tried to boot with a breadboard attached. Not a brilliant idea. Without the breadboard I could get the green light (ACT) to blink a few times. 2. I upgraded my B+ software to the latest and greatest on the B+ (I'm using Stretch...

The red LED lights up on the board, but the green LED never does. The monitor says there is no sync. The power is from the 3B+, a...

This stream is very out of date. I just tried "ssh -X pi@ipaddress" and it brought up XQuartz which made a small sizable window on my Mac.
It is a wonderful window into my RPi 3 B.
