Hi!
I want to connect the OLED display (Adafruit 938) with SPI by a longer cable.
So while it is working with short cables, with long cables I got problems.
On my scope the signals are pretty distorted.
So my first thought would be to reduce the SPI speed, maybe that would help.
How can I reduce the SPI speed on Metro M4 board?
Thanks in advance!
Kind regards,
Alex
