Well finally sat down and cracked open the PSoC4 box and decided to start on the software side of the project.
After a little searching around I finally found the down load on Cypress website. (After the fact I found the direct link on the 100 projects page.)
Installation was strait forward and went about as expected. Grabbed one of the demo projects, loaded up the project, plugged the PSoC4 into my PC, and programmed it.
And just like that I had a blinking LED.
Next tried to modify the code to go from a blue blinking led to a red one. Spent a good hour or so searching around the code and the web on how to change the IO pins around. First started looking in the headers and C and there was nothing that looked like the pin or IO bank info. Next played around in the TopDesign.cysch and the IO pin properties and no dice. Even searched google for documentation (found some documentation but not what I needed). Finally clicked on the cydwr entry and found the magic page.
After that bit of exploring I started playing around with moving the IO, adding more IOs, and multiple IOs inverted from each other. So now have a led that blinks back and forth red and blue.
The PSoC Creator software is very graphical. I normally program my other micros in assembly so this is a new experience. The ability to drag and drop modules like IO pins, PWM, and rewire them by drawing the nets is very nice and make for quick prototyping and testing. Next up I need to brush up on my C skills and see if I can patch together a quick utility that will take the frequency output from one of my moisture sensors and allow me to read it remotely via the UART.
Once I get that up and running I think I am going to take that, the prototype sensor, and a Raspberry Pi and make a quick data logger. I am hopping to have this up and running before I head home for vacation. That way when I get back I should have a good data set to work from to verify the sensor operation.
