PSoC 4 Pioneer Kit Community Project#01 - Blinking LED

Hi,

The 'Software Setup' steps 1-6 link is broken. I looked at the zip file, but the main.c just contains essentially this:

#include <device.h>

void main()

{

    Clock_Start();

    PWM_Start();

    for(;;)

    {

    }

}

Where would you have  defined what connects to the count, start and clock pins on your schematic that you've shown? (I don't have a PSoC board, I'm just curious). The other files in the zip didn't seem text-readable, but I may have missed it, or is it done on the IDE somewhere?

The pic that Gagan put up is from the creator IDE.  The connections are made through the schematic entry shown in that picture.  That schematic and the main code are all that is needed.  : )

Hi Shabaz,

Good question!

The main.c contains only the 2 lines needed to 'start' the 2 Components - PWM and Clock, that are placed, wired, and configured on the project schematic ("TopDesign.cysch").

That's all the CPU needs to do! The rest of the design runs entirely in hardware with no CPU intervention required.

To see how the 2 Components are setup, simply double-click them to open the Component configuration window.

You can setup your global chip resources like Clocks, Pins-outs, Interrupts, DMA,etc. in their respective tabs. Here is a quick tutorial video that shows the workflow with the Pin Component as an example. http://video.cypress.com/video-library/video/PSoC-Software_PSoC-Creator/PSoC-Creator-Tutorial-Working-with-Pins/1768525420001

To get started, you will need to install the free IDE - PSoC Creator.

EDIT - thanks for noting the broken link, fixed now!

Hi Chris, thanks for the information. I couldn't see from the main code nor the schematic, where the PWM depth is set. Has it defaulted to (say) 100% and requires a function call in main.c to change it?

Hi Gagan, Thanks for the information! It sounds great. I'll try out the free IDE to experiment, downloading it now.

Hey Shabaz, you would double click on the PWM component (the green and grey PWM block shown in the schematic above) in Creator and it opens a configuration dialog called a customizer for you to set parameters like Period and Compare values.  Then you can change those values in code later with API calls like PWM_SetPeriod() and PWM_SetCompare() among many other things.

I see! It sounds straightforward and not so scary any more :-)

The IDE installed fine, and I was able to compile a demo program.

Just in case anyone tries it with Windows 7 64-bit: For me, when I tried to compile, it said a license had expired (although I've not installed this before), and it looks like an issue with ARM's Keil software. Followed the Help->Register->Keil process to get a license code, but the code didn't work. There was some forum where basically these steps had to be followed:

1. Go to C:\Program Files (x86)\Cypress\PSoC Creator\2.2\PSoC Creator\import\keil\pk51\9.03

2. Copy the _TOOLS.INI file to TOOLS.INI

3. go into the UV4 folder

4. Right-click and 'Run as administrator' on UV4.exe

5. Go to File->License Management, and enter the key there

6. Close the UV4.exe program, go back into the IDE, and re-do Help->Register->Keil, and the license was already there (I re-entered it there to make sure).

7. Now the compile will work!
