Ever since I received my PSOC 4 Pioneer kit from Cypress I have wanted to play with this little mixed-signal Programmable System-on-Chip (PSOC) developer board. I love developer boards, providing that they are priced in a way to entice me to not only open my wallet but also make time in a busy schedule. I think my kit was free after winning a swag bag from Adafruit that they themselves obtained at the Open Hardware Summit and gave away on their weekly streamcast. Ultimately it was the invitation to beta test datasheet.net which also was included in that pile of swag that led to my getting involved with Hackaday.
What is Programmable System On Chip?
So what is a PSOC 4? A quick summary is that it’s based on an ARM Cortex reduced instruction set processor (RISC) and is somewhat capable of supporting shields based on the Arduino footprint, and it also uses a bright red PCB that I have come to associate with a Sparkfun PCB. What doesn’t show is the fact that this programmable system on chip has programmable analog function blocks in addition to programmable digital logic blocks. There is also some supporting input/output circuitry such as a multicolored LED and a capacitive touch sensor directly on the PCB.
This is an intriguing amount of programmability, so much so that Newark/Element 14 highlighted a “100 projects in 100 days” event on it.
Enter the IDE
Over the years I have had to create or install many Integrated Development Environments (IDE) that linked hardware to software. Knowing that you had to, and how to, implement an IDE was part of being an engineer. Nowadays with the Arduino type environment the user has an IDE pretty much as soon as they click on the executable which I find to be one of the best aspects of the genre. It was so quick in fact that I was able to get my teenaged son into writing his first program even before he remembered to do massive eye-rolls and make sounds of utter disdain. He did give up however, just shy of learning how to have the Arduino make sounds of disdain on his behalf.
