PSoC™ 5, 3 & 1 Forum Discussions

When I attempt to program a PSOC5LP (from PSOC Creator 3.1) using the Rev B miniprog3, the Program operation often halts/does nothing (indefinatly).  Unpluging the USB cable to MiniProg3 releases the stuck program operation.

Similarlay, the Select Debug Target dialog is generally rather slow / non-responsive.  (Eg selecting the window and relocating on the screen, or selecting port properties can take 10 seconds to update)  Often to get anything this to work, each time I try to program, I have to first unplug/plug in the MiniProg USB.  Then select debug target and connect, and then go to program.   This works 25% of the time. 

Programming mode is SWD protocol with reset acquire mode, external power, and 5 pin connector.  Clock speed has been lowered to 200kHz.

I suspect the problem is my prototype hardware with the PSOC, but have no idea what - as flakiy behavior isn't much of a guide to root causing the problem!

My PSOC hardware has 3.1V applied to Vddd, Vio, and Vdda.  1.8V is applied to Vccd and Vcca.  I *believe* power is applied to all pins and they are properly bypassed.   (The package is 68 DFN - which was very difficult to handsolder.  I've inspected w/microscope and believe all the pins are soldered.)  My hardware also lacks a proper programming header, thus I've place the 5 pin connector on the end of the miniprog3 and have 3 inch wirewrap wires going to the hardware.    Miniprog3 is connected to the PSOC pins labeled Vddio1, SWDIO, SWDCK, CFG-XRES, and GND (VssD, VssA).

Once programmed, thus far my rather simple programs (LEDs and UART output) seem to always startup as expected with power cycle, or when the miniprog releases reset.

I know there are lots of unknowns here - but possibly others with more than a few days PSOC experience have tips other than re-run the PCB.  (That will happen once I know most of what is wrong with in....)

TIA.

 Hi,

Is it possible to interface a camera with any PSoC?

is there any existing library available ?

Thanks

 Hi everyone,

I designed a board which contain 20 capsenses with a PSOC5LP CY8C5888LTI-LP097.

My problem is that when I touch one capsens like for example P0[2], several capsense P0[4],P0[1],P0[6],P0[7],P0[0] are activated also. It's like all the port 0[xx] is unsettle.  I don't understand why, I tryed to respect design rules, I put capacitors on VDDIO as you can see in my schematic. I use 2 channels for capsense, so I put two CMOD 1u capacitor as in the datasheet.

The weird thing is that capsense's tracks are not close on the PCB but the capsense is activated (see my PCB image). 

My track's width are 0.2mm with a cleareance of 0.19mm

So if you have any sugestions let me know

Thank you

Hallo Community,

I currently trying to bypass a digtial signal trough the PSoC5. I attached an image to clearify the configuration.

The pins 2 and 4 transfer the clock signal of an external BiSS interface which is set to 2 MHz and Pin 3 and 6 shall transfer data. Pin 2 and 3 are connected to an external Biss-Interace and pin 4 and 6 are connected to a sensor.

But it does not work. I can not set up a connection. My question is: What may causes the problem? Could the internals of the PSoC destroy the signal or slow down the clock signal?

I checked if bypassing is possible with analog pins and it worked.

Best regards,

Hi

I am trying to pass an audio signal as shown in the schematic but the part I have the problem is between the filter to DVDAC(12 bit)
unfortunately I can't make the DVDAC output any normal signal
all the other parts work good
also when I used VDAC8 it worked ok but i need 12 bit resolution from the filter.
(I use the opamp in order to get enough current for the speaker
did I place the capacitor for DVDAC on the right place

please help me with that
thanks

Hi, I want to drive led with the help of timer output  but i am not able to do it. i am confused with the timer block. Please help me with an example project how to get the return value from a timer.. how to interface an lcd and led with the timer..   

 Hi everyone 
I want to ask about the name of microcontroller used in PSOC 5lp and how many cores it uses?

and the same question for GSM SIM900?

Thanks all,
