Here are some new videos on getting started with the PSoC 1 GPIO (general purpose input/output). The videos provide a look into the basic architecture and provide pointers on how the GPIO properties can be configured and used.
There are two parts to this video:
Part1 - Talks about the architecture and drive modes in PSoC 1
Part2 - Talks about the shadow registers and GPIO-Interrupts in PSoC 1
Let us know if you found the video to be useful.
It is useful for a freshman!
