PSoC™ 4 Forum Discussions

Hello All,

I am continuing to experiment with my -043 kit, mostly using  the sample code provided to help get a feel for how the device works and perhaps to even get some some flashes of inspiration as to how I might better use it.

As part of this work, I've extended the "breathing LED" example code to use multiple LED's at different frequencies and duration rates.  To do this I've just been adding PWMs. 

When I got to PWM_4 and PWM_5 however, the compiler began to complain with a cryptic error message about it not having a 'valid placement for pins or for a functional block'. 

My first thought here is that there may be a limitation as to the number of PWM's that I can invoke, however in browsing around the web I've seen some articles suggesting that up to 24 PWM outputs are available with the psoc4 family.

So am I misunderstanding something, or is there some 'secret sauce' involved in using more than 4 PWM's?

hello guys,

i made a custom pcb using 

psoc4 CY8C4245LQI-483 ,

i manufactured 4 PCBs - i am trying to program with miniprog3 

in 3 of my custom circuits  i get the following error :

" Unable to acquire target device..." 

1 of my custom circuits seems to work flawlessly i can program it , debug , control gpio .

after double checking my schematic i saw an error , i accidently routed the  VCCD pin to 3.3v instead of  

connecting it to gnd (image of how i connected power is attached) , 

do you think this error is a critical design error ???  (i saw some desgins where u can connect it to 1.8v)

do you think this might be the problem ??

Hey,

I did the getting started AN but now what's the next step in order to have a better understanding the PSoC 4.

Maybe I'm some lost on my own path to learn but I would like to create a simple APP using BLE to share data. should I create a private custom profile?

So, what videos/articles do you recommend to me? I'm a absolutely a beginner.

Hi all,

Can someone explain why I might be getting the following behaviour from a CYBLE-022001?

- CYBLE configured in observer-only mode: successfully gets scan results for all connectable (undirected) and non connectable (undirected) broadcasters

- CYBLE configured in GATT Client, GAP Central + Peripheral mode: only gets scan results for connectable (undirected ) broadcasters but does NOT scan any non connectable (undirected) broadcasters

In both cases, the broadcaster is another CYBLE configured as broadcaster-only with non connectable, undirected setting. Broadcast min/max time is 1000ms.

In both cases, the "listening" CYBLE has scan setting of scan window/scan interval is 30ms, timeout 30s.

Does anyone know if it is possible to set the logic thresholds for the RX input pin of an SCB component is the same way as you can for a discrete IO pin? The architecture seems to suggest it should be possible in hardware but I cannot find how to configure it in PSoC Creator.

For background, I am trying to interface with a FT230X FTDI USB converter chip which has IO at 3.3V maximum, but with 5V tolerance on the inputs. My PSoC (actually it is a PRoC BLE Module, but I posted here because this question should apply to any PSoC/PRoC 4 chip) has to run at 5V for other reasons. It works fine as a prototype, but I am concerned that the CMOS high logic level is marginal (spec says 0.7*VCC minimum = 3.5V). Actual tests indicate the threshold is 2.2V on the prototype, but I do not want to chance my arm! The LVTTL specification of 2V minimum would be safe, but I do not know how to set this for the SCB component as opposed to a Pins component.

Since the threshold setting is per port, I layed out my PCB so one other 3.3V input was on the same port as the SCB expecting that setting that pin to LVTTL would set the entire port including the SCB RX (and TX). But when I try doing that in PSoC Creator 3.3 I get the following error:

pft.M0032:Pin Error: (Mixed Input Threshold. Cannot assign 'USB_ON(0)' with Input Threshold LVTTL to physical port 1 where '\SCB_2:tx(0)\' with Input Threshold CMOS is already placed.).

This is followed by error messages about the SCB rx and tx pins not having the same <vtrip> as the pin USB_ON.

But there is nothing on the SCB configuration about setting the Input Threshold.

Hello,

I am a new member in this forum and I don't speak English very well.

I'm working with CY8CKIT-046 PSoC 4200L and I'd like to build a Chebyshev filter. The scheme is shown in Figure1.

When I build my circuit I can't connect the OpAmp3's output pin with the external resistor R4a and P3minus with R3b (and C3a) because these pins are not present as output ports (see Figure2 and Figure3).

Is there any way to solve this problem?

Hi

Can anyone give me some advise on using the watch dog timers.

I have selected it as having an interrupt every 1 second.

But not exactly sure what to call, or how to write the interrupt.

I am sure there is a app note but I am having hard time finding it.

Thanks for your time
