Hi - I ran into PSOCs a little while ago - and I'm having trouble figuring out *what* exactly they are... Cypress calls it a "mixed signal array" - which is a term that I'm not very familiar with. They say it has a microcontroller, along with a number of configurable "elements" (that can be set to be ADCs, DAC, timers, PWM, etc.) But my understanding of a microcontroller is that it essen...

Hi everyone, So I'm working on a new project where I want a web browser to a certain site to open whenever my USB device is plugged in and send some data. I plan on using a Cypress Encore chip and am looking over all the app notes and sample code but most of it just directly sends data like a mouse or keyboard. Is there a good resource on sending commands to a PC/Mac? Please let me know if you...

I would like to use an FPGA for a motor control application. I have worked with FPGAs before and am comfortable with what needs to be done inside the FPGA, where I need some advice is how to interface the FPGA with the outside world.
