PSoC™ Creator & Designer Forum Discussions

 An LED driver component for matrix and 7 segment displays.  some of the feautres are:

1.) The component supports 1 to 8 commons.  
2.) The segments and common signals can be inverted for use with driver transistors or for common anode / common cathode displays
3.) The brightness of each common can be controlled with an optional PWM built into the component.
4.) A macro is included that breaks out all the signals to make it much easire to get started
5.) API are included that make it very easy to display numbers (signed decimal and hex) as well as strings for use with 7 segment displays.
6.) All hardware based solution, no interrupts or CPU time required.  "set it and forget it" operation.

My first component submitted to the community!

I  have an irritating issue with PSoC Creator version 2.2 and PSoC5 running under Windows 7. When I am in one of the editors and want to proceed to debugging I click on the debug icon (looks like an ant) and the software does its own thing (compiling when necessary etc.) and then moves into the debug environment.  The problem is that maybe 60% of the time, it doesn't set the pointer/ProgramCounter to the first instruction in the main procedure, it simply opens a Disassembly tab and seems not to place the ProgramCounter anywhere, or maybe above the first line in the window (I can't tell- there is no yellow arrow). Although I am sure it is irrelevant, the first line in the debugger is:

0x00000000 <__cs3_interrupt_vector>:

 Trying to run results in indeterminate results. The only way is to click on the Reset icon (double rewind arrow) and sometimes you even need to do that twice. If you are in the disassembly window it will take you to the correct point, but still in the Disassembly tab.

I have tried to find any pattern as to when I invoke the debugger (like completely build before I start) but I can find no pattern to it.

Is anyone esle seeing this problem?

 Hi All.

Is there a plug-in / Gui available for PSC Creator to help with the graphics design on say a 128X64 graphic display?

A couple of issues that need addressing -

1) Global properties, the OpAmp Bias and Ananlog Buffer properties both were set to low power,

so sine wave distorted. Those should be set to high power.

2) Because the A Buffer is not R-R, its exacerbates the distortion of the DAC output when close to either

rail. Maybe a note should be added to ap note covering this.

3) As an exercise, to eliminate the distortion in 2), I added a PGA, set its G < 1, to get waveform away

from rails, and woulnd up with a highly distorted waveform, ? Not sure why.

Note A Buffer was only loaded with 10M scope probe in all observations, maybe in case of 2) high load

might actually improve output distortion.....?

 Hi,

When using PSoC Creator, it is generally assumed that if a particular component feature can't be used with the current options (e.g. it's using a fixed-implementation), it will be greyed out. However, this is not the case for the "One-shot" and "One-shot (Halt on Interrupt)" run modes when using a fixed-implementation Timer with a PSoC 5. 

This is annoying, as you can continue about building your design, and only discover it's useless when it comes to building the project hours later. 

It also makes no mention of this under the section "PWM Component As A Pulse Generator" in the PWM datasheet (in the second bit, where it introduces a timer and says it's less resource intensive than using a PWM component). I think you should mention that this is only applicable to PSoC 3.

I am relatively new to Psoc5 and Creator and am re-acquainting myself with C++.  I am having difficulties getting a particular program to build.  I know that Creator is C based but that one can also "force" it to recognize and compile C++ code.  The program is extremely simple:

#include <iostream>
using namespace std;

int GetFibNumber(int FibIndex)
{
    if (FibIndex < 2)
        return FibIndex;
    else
        return GetFibNumber(FibIndex - 1) + GetFibNumber(FibIndex - 2);
}

int main()
{
    cout << "Enter 0-based index of desired Fibonacci Number: ";
    int Index = 0;
    cin >> Index;
   
    cout << "Fibonacci number is: " << GetFibNumber(Index) << endl;
    return 0;
}

In the Build Settings associated with all .c files I have added "-x c++" as a custom flag in the command line.  The errors I get when I build this is:

prj.M0120: undefined symbol `Reset' referenced in expression

prj.M0120: The command 'arm-none-eabi-gcc.exe' failed with exit code '1'.

Any ideas what I'm missing?  Thanks.
