Hi Every One !

I would need some help regarding noise generated for the Delta sigma in single end configuration.

As you can see in the schematic as result of array scanning I am geting pulses which votage depend of the pressure applied to every cell in the array.  My Vdda is 3.3 v . The issue is that with no pulse, ( checked with osciloscope) there is noise that  you can watch in the graphic display picture.

The only way to avoid that is using a PGA before the Delta sigma..

I cannot undestan that. !!!!

And even using a PGA,  I need to filter trough  code , like high pass filter values above 0x80, wich represent almost a half of the ADC range.

I woul appreciate very much any help.

Hello Everyone,

Could you help me with my ADC, I cannot get it Right I want to use ADC for input range of (+/- 1.25) in a differential input range with a refrenve of vdda/4 = 1.25. could you tell me what is the voltage range and the corresponding digital value in decimal?

Thanks.

 Can anyone tell me what the problem I have with CY8CKIT-050 to measure the voltage of a resistance of 10 k to 100 uA idac is not true and then varies the channels are 5 v without having connected to the resistor. How do I can find the true voltage?

Hi,

I measured that the time for execution of the EEPROM_Write function is ca. 15 ms, which is far away from the typical value of 2 ms specified as "Single row erase/write cycle time". Is that possible or does this function have so much overhead time because it is doing a single row erase and write ?

BTW, I used the CySetTemp() function to compensate for temperature influence.

Thanks 

Hallo,

I want to design a project, where a reference is brought out on P0[0] with VDAC buffered by Opamp.

At the same time I want to measure the P0[0] with ADC_DelSig over AGL[4].

Please look at the attached project for full understanding.

The project works fine for Analog Mux but with the Analog HW Mux I get the following Error Message:

"Signal "\Opamp_1:Net_29\" is expected to connect to only one GPIO analog pin but instead it connects to "\Opamp_1:ABuf\". Please fix the connection."

(Please do not care about ADC_DelSig sampling or AMux switching, this is done later.

Only concentrate on the routing problem!)

Hi.  I am playing with PSoC3 USB bulk data transfer using CyConsole.  all is working fine.

I can now manipulate the firmware per my application.  However, I will need the PC (software) side.

Is there a CyConsole code/project for the PC - in VB.net or VC#.net?  Thanks.

Hi.  how do I change an IO pin from an output to an input pin (or vise versa) in code? 

The datasheet for IO has one API called CyPins_SetPin() but its usage (API) wasn't described.  Is this what I need? 

The code generated for the project (Pin_1.c) does not even contain this routine (?)

This API is for use with PSoc3 and PSoC5LP which are both of the devices that I am using.

Please advise.  Thank you.

 Hello everyone,

I'm trying to make my own PSoC 5lp board currently. I'm wondering how can I draw CY8C58LP chip in schematic and generate pcb as well. Thanks a lot!
