@robski : some time ago I made some trials with Thonny but I was not really successful.. I will git it a new try.. at least for followng the remaining space, deleting the temp.py and so on
I am surprised that none of the 109 viewers proposed the proper way of doing. Or maybe the PaHub is not their concern ?
Anyway and for future beginners who could face the issue.
1)There is no need to add the PaHUB as a component as with the other I2C captor
2) These captors must then be declared as PaHUB and not as port A
Thanks for the answer. So what I thought to be a last chance solution becomes the rule. In the videos and tutorials I have been through so far, this question has never been raised. One is told how to download a program to the device starting from scratch but never how to download program number 2..
