Which board did you test that with? Seems that Arduino IDe 1.8.5 or latest 2.0.1 has issues with Arduino Nano, while it compiles OK for STM32 (bluepill boards)

Hey,
trying to get it running with Arduino Uno and Nano, HCMS-3904, Example 1 - seems from the example that wiring shold be:

Ardu HCMS-3904
+3,3V - VLED (Pin 3) - that is comming from PSU
PIN 6 - Data In (Pin 4)
PIN 7 - RS (Pin 5)
PIN 8 - CLCK (Pin 6)
PIN 9 - CE (Pin 7)
PIN 10 - RESET (Pin 12)
GND - Pin 8 & 9
+3,3V - Pin 10 & 11 - that is comming to from PSU

Correct?

Serial ports on Ardu spits out the procedure for all example steps, yet the scope doesn't show any clock running on PIN 8 of Ardu, and the HCMS is not working.

What am I doint wrong here?
