PSoC™ 5, 3 & 1 Forum Discussions

Hi Everyone,

Here is a question that was asked during the PSoC World Virtual Conference that was held during December 12-13, 2012.

Q: "Where can I find a list of I/Ps available for Designer?"

A: I/Ps for Designer (a.k.a. User Modules) are available as configurable, pre-characterized blocks that implement a range of functions and peripherals. 

More info on User Modules - http://www.cypress.com/?id=2522&rID=40633

We are hoping that these question/answers will be helpful for those who could not attend. If you have a question about PSoC 1, feel free to start a thread and pour in your doubts.

I am trying to learn more about the Digital Filter Block (DFB) to use in my application. I am interested in using the DFB to perform a hardware PID calculation because it seems to be a very powerful tool that will not use up as many resoucres as other implementations.

I have read through the DFB datasheet and the DFB section in the TRM, but I am a little confused with some of the descriptions. I am trying to walk through the DFB example project included with Creator to learn how and why the developer programed the DFB, however, while stepping through this code I have hit a wall. On line 6 of the DFB assembler code, the developer used the jpml() instruction with the condition "in1". On page 38 of the DFB datasheet the description for 'in1' mentions a 'Channel 1 Input Register', but I cannot find a reference to this register anywhere else in the DFB manual or TRM. I looked for a 'Channel 1 Input Register' on the diagram on page 22, but only found a 'Stage A/B' register. Are these the same thing?

Am I looking in the wrong place? From my understanding of the code, the 'jmpl()' instruction will not execute until the condition is met, but I don't know how to put an entry into that register. Can anyone help me out?

For clarity I included the example project as an attachment below.
