PSoC™ 5, 3 & 1 Forum Discussions

hi everyone iam considering switching from FPGA to PSOC....can someone tell me the advantages of PSOC over FPGA??

I realize that lower power consumption is one of them. what else?? 

 what do you mean by the text 

the junction sensor is isothermal with the cold junction ??

(in context to industrial application - under thermocouples)

thank you !!

Description of PSoC 1 is incomplete without the mention of switched capacitor blocks. It is this feature, which makes the device unique. Switched capacitor blocks are highly configurable hardware blocks which can be configured to work as an amplifier, comparator, modulator, filter, ADC, DAC, integrator, differentiator and so on. And the story doesn't end here; you can even tune parameter of the function during run time. For example, changing the gain of amplifier, changing threshold in comparator, adjusting cut off frequency in filter, changing the integration time constant etc.

Here are some collaterals associated with switched capacitor blocks:

Last but not the least...Technical reference manuals are the ultimate resource to understand any feature of PSoC 1 device in great amount of detail.

 Hi,

I have many succesful PSoC 3 and 5 projects under the belt, including some quite complex designs.

However I have never used PSoC 1 - yet!

So what's the best way to get to know PSoC 1? Which dev kit would you recommend?

 Hi, I'm starting to program in PSOC and I have problem with the ADCINC, I made a program for read a LM35, but when i conected it, to psoc it only read cero, if a remplace with a pot i can see the variation, i have been searching a explain but i cant found it. I hope that you can help me. I anex the code. excuse me for me redaction y and the coments in spanish.

#include <m8c.h>        // part specific constants and macros

#include "PSoCAPI.h"    // PSoC API definitions for all User Modules

#include "stdlib.h"     //incluimos la libreria para conversiones

#include "delay.h"      //incluimos la libreria para retardos

#include "string.h"     //incluimos libreria para punto flotante

#define _FTOA_TOO_LARGE -2

#define _FTOA_TOO_SMALL -1

/*El programa realizará una conversion analogica a digital para detectar temperatura mediante un sensor LM35

y visualizarlo posteriormente mediante un LCD con barra grafica.

Hello,

I try to realize a synchronous demodulating of a signal modulated in 100khz.
I test the use of PSoc1. The use of " Modulation
Inputs " in a  SCC Block seem to allow it. But I do not how see routing this input with
PSoc designer 5.3.
