Today involved a lot of fumbling and flailing.
I have some L298N ICs for stepper motor control, but found some great kits that made development easier and went with those. I also purchased an Arduino Stepper Motor Shield which is used in Project 45 of the 100/100 challenge (it has an L298P). Neither worked. I got the same result with both setups (which actually in some sense is a win showing it isn't a HW fault but a SW one). It was a massive let down. In going through the Project 45 code/layout I found one of the pins on the PSoC 4 didn't go to the correct labeled path. This should be a bug, but for some reason is not. I also verified the pin to the Arduino and that some pins on the PSoC 4 kit are called out to the Arduino board, but Arduino doesn't actually connect to them. Serious disappointment to watch the Project 45 video, read the literature and not get the same results. Also, went through the logic and never saw it make sense per the L298 logic sequence. I could come up with an alternative that would work, but Project 45 code/layout and Arduino don't match up. That may be why the thing doesn't work, is because the logic and layout doesn't work.
Found a similar issue with Project 41 for thermistor. Without experience, I wouldn't have right away looked at the system and identified it not able to work without voltage across the voltage divider. The documentation and the code do not reference setting this up. Attempting to add this also proved difficult. There wasn't an immediate obvious way to pull 3.3VDC from the PSoC 4 pin to another pin. Part of the advertisement for PSoC is that you can connect any pin to any pin externally or internally, but reviewing the list of pins to do this, several were missing. I'm guessing there is some place to unlock something and really hack and break.
In the same Project 41, they reference opening up the Bridge Control Panel. This wasn't obvious, but once found and open and connected, it never read the info and displayed it to the graph. We identified a UART output pin, scoped it and saw it talking, but the BCP didn't have any clear way about displaying its' data (or even collecting it). Without the voltage on the voltage divider, the graph still should have been outputting something even though it would be gibberish. The graph remained blank.
These two projects aren't the first that I've seen like this. I'm not sure if others have just gotten lucky and don't want to admit it, but some postings where code is requested, people won't furnish it and in some of the setup instructions, things are blatantly missing. It is very apparent that what is published doesn't match what is produced.
As negative as all that sounds, it is still very enjoyable. I love the creator layout/design interface. I'm proud to be a part of this competition and enjoy working with the hardware.
