FP-30 User’s Manual

Chapter 8 Interfacing with the hardware board (On-board connection) 88

Tips for connecting

・

The cable length between FP-30 and the hardware board should be 20cm
or less. The shorter the better.

・

The communication is stable at a slower clock speeds.

・

Using one I/O data line is stable than using four.

・

In additional to SPI signal lines, it is required to connect the

SRST (Pin 19:

System reset signal). Note that this signal is not the SPI flash reset signal.
