Having been a professional programmer in the past Arduino got me back into embedded and was very helpful to my profession.
BUT I did find the forums next to useless with many asking how to blink a LED make a robot and do facial recognition with and Arduino Uno (?)
I soon drifted away to the AVRFeaks forum and studio 7.
Now Atmel has been bought by PIC, who have missed the value of getting hobbyists who are also professional Engineers on board. Their new compilers and such are now heading away from being free.
When at work Engineers are under high pressure to meet product deadlines so becoming familiar with various MCUs in work time is not possible. You are in a situation where you have to run immediately, so you tend to go with what you know.
It is very common for Engineers to "go with what they know".
When working in Taiwan I have even seen many telephone PABXs that have used 8088, surely not suitable.
With developments in Arduino there have been boards the likes of the BluePill and and Teensy 4.0
These are a very interesting more high end development.
To take advantage of this there need to be a different forum to this one.
Yes, I am just a requester but a better forum can and will happen.
I would like to see it remain under the Arduino banner.
