if I just want to erase the memory, write it

I took another sensor and tried it again and it worked, I'll describe it later, the first plate remained hanging in

I gave up on this and got another board, chatgpt told me that there were quite short timeouts set in rdwr_phy62x2.py, I increased them to 1 see...
