The tests aimed at improving quality have already produced initial results. In the download section, the protocols can be found; in particular, the Read and Write signals were measured with an oscilloscope.

The following image shows the timing of Read and Write operations in the system...

Based on these results, the delay times in the Arduino software of the memory module were adjusted:

On the left is the new software, on the right the previous version. In general, the waiting times were significantly extended.

An initial test with software that adds the numbers from 1 to 16 was successful. Based on these results, the clock generator (currently: 10-20-10-10 with 5 ms pause) will also be revised.
