I come to conclude this topic since I have already received the module with pca9685 and I was able to test it in real time and I can confirm that everything is working correctly. My apologies for having raised doubts about this component and thank you for the help from the flowcode team.

As promised, I will post 6 screenshots. The first 3 refer to the configuration in "software" mode and the next 3 in "channel 1" mode.

sorry, the order is backwards

this is the test program

The simulation order is: 1,2,3 for software mode and: 1_1,1_2,1_3
for channel 1.
For reference, the same tests were performed on channel 2 and the results were the same.

These three screenshots refer to software mode

each capture represents the three configuration steps plus the loop

I'm out at the moment, as soon as I can I'll take a screen capture with the software configuration and the dedicated channel configuration.

Hi Martin, thanks for the reply. I've only simulated with Proteus so far, but what I noticed was the difference in setup times during the four macros (separated by a 1-second delay) before entering the loop. I don't yet have the PCB with the PCA9685 chip physically with me to test. I usually test wi...
