Hi, I bought a 1602 LCD and I can't figure it out.
I have this Data sheet :
https://www.crystalfontz.com/products/document/964/CFAH1602XYYHJP_v2.0.pdfI looked at it several times and couldn't find a satisfying description of how the thing communicates,I found that there is an example on page 35 tried it but no luck
.
I understand the general idea but it looks a bit weird, It doesn't have a clock input only 8 pin data and 3 pin control.
If it just scans for data changes why it is not working?
it is probably a timing problem but I don't know the operating concept ...
do someone have experience with this LCD ? (but no arduino please
)
