Hello ,I use the uart in the ardunio of PYNQ Z1 and Z2.
The python code is like this “lib.uart_read(device,number,len(number))”.
It shows that the length of data should be configured by user.
My problem is how long could the length of data be(see len(number))?
I try to make the length of number be very long, It seems some thing wrong. So I think there is a restrict of the length of data for uart in Pynq’s Ardunio to receive.
