Hi
ARDUINO IS UNSTABLE!!!!!!!!!!!!!!!!
Ok now you can throw rocks at me...thousands of users with the same problems.
I use 3 computers:
1.Win7...32BIT
2.Win7...64BIT
3.Win10...no need to say but 64 bit
I started to upgrade from ARDUINO 1.8.2 to 1.8.5
The last week I spend hours on each pc to get the downloading to work AGAIN.
The COM PORT shows in TOOLS and is ticked but i get the STK500 SYNC ERROR after the upgrade.
Then I start following the list of possible fixes .. uninstall driver...re install..re boot pc...swap cable..swap
arduino..uinstall arduino ...uninstall driver..install driver first ...now install arduino..re boot pc...repeat the list
start re doing all above in a changed order.
Then all for no apparent reason the usb port works and download the HEX file, now do all above on pc2 and
pc3 over and over and over...... until it works.
Once i get it to work AGAIN I love it...but
