 Hello world. Hey I got that right! Ok so I am just getting into the PSOC world. I have done some work with other uc's in the past, but I wouldn't say that I am any good at this by any stretch of the imagination.  I purchased the -050 kit, ran two examples and managed to short something out. I'm not sure how I did it. It was sitting on my desk reading an analog value and displaying it on the lcd one minute and the next total failure. Anyhow, I ordered a new kit and got it in today. I am a little gunshy, but determined to get this right.

   

Just a little background, I am an EE who graduated in December 2013. I am a control systems engineer. I have been doing system design since May 2013. I was thrown into the fire, so to speak, and am constantly learning everyday. 

   

On my own time, I began looking into microcontrollers and ran into the PSOC. Since I am in the controls world, I work with PLC's daily. I thought that I would like to take values, analog and discrete, and make them available via Modbus TCP, essentially a Modbus client.

   

I have looked around for a while, but I am lost. I have been to modbus.org and looked at the standards.  I have read numerous articles and Web pages, but I don't know where to start. I know that I am asking a lot, but I think I am going to need some hand holding?!?

   

Is there anyway to actually do this with a PSOC 5? I understand how Modbus works. I understand stacks. I have never done any real project with the PSOC or communications. Anybody have some advice?
