PSoC™ 5, 3 & 1 Forum Discussions

I'm using the datapath with FIFO0 to read in 32 values ( (8) 4-byte DMA requests driven by the FIFO empty flag) place them in A0 and compare with another value using the built in register compare. The seven bit counter manages the minor loop count of 32, while A1 holds a major loop count for tracking how many times the minor-loop executes. So far this is contained in one UDB, which is what I want, but I have an issue - once the minor loop completes, I need to hold those values so that a series of these results can then be fed out from multiple instances of this component in parallel. 

Since the local SR can only hold 8 bits (1/4th of my necessary results per buffer) it means I have to chain 4 of these in order to get my necessary storage...this essentially renders 3 additional datapath components useless - is there a way I can store the boolean outs of the compare operation into FIFO1 taking advantage of the 32 bits there and keep this component limited to a single UDB?  Even if I could store this boolean data in the FIFO bitwise can the FIFO be output to a pin in "series" or this out of the question - would I still need to take advantage of the register? 

The endstate is that I'm creating a massively parallel PWM to drive "dumb" RGB panels, but each color needs to be shifted in simultaneously since they are tied to the same clock, and there is no method for pre-writing then latching the data, like many PWM chips which have a double buffer for current data and latching in new data when it's ready...the output of the panels has to be disabled while the new data is being written, hence needing to push all 32 values at once, otherwise you see the new data shifting in and the old data shifting out. Leaving the OE low too much kills the brightness of the panels.

Any advice would be much appreciated.

 For some time I have had to manually add various components to the lib file in order to have the project compile properly.

The project lib folder is empty.

Ideas?

Hello Every one,

I want to transfer data via SPI (Slave) using interrupt. I found one example and tries to implement it. But its not doing things as its suppose to do in my program. I am attaching my project please have a look into it and suggest me with possible solutions.

Looking forward for your reply.

Hi all,

I'm working on the porting of Riot-OS, a realtime OS, on the PSoC.

I found information on GitHub of a first port on a previous release.

https://github.com/RIOT-OS/RIOT/wiki/Board:-CY8CKIT-050-PSoC%C2%AE-5LP

Is this project followed by Cypress ?

Is someone working on the topic ?

Thanks in advance

Hi

During my install of PSoC Designer 5.4, it detected a problem with installing Adobe svg viewer.  However it did complete the installation although did complain about it a couple of times.

When I run PSoC Designer, it loads up but when I load an example project, I get an error message saying it is required to re-install Adobe svg viewer.

Now just how does one go about that???

According to Adobe, support for svg viewer was discontinued in 2009!!

I am using Windows 10.

Also, I couldn't find a way to search the forum for a particular word - it seems you can only search the Cypress website complete?
