Hello,

Recently I have been playing with the CapSense block in PSoC 4.3 with the specific aim of trying to maximise the rate at which I can poll the electrodes for raw data.

PSoC gives a calculated value of scan time for your particular setup of electrodes when you double click the capsense block. I have found this time to be VERY different to timing the difference between CapSense_ScanAllWidgets() and the time at which the block becomes "not busy". I have managed to decrease this time though several methods but I am still not close to the scan time given by PSoC.

My methods for reducing the time so far have been to attach all electrodes to one widget and preload this widget using CapSense_SetupWidget(), prior to scanning with a call to CapSense_CSDScan().

I have also found a variable named CapSense_CSD_ANALOG_STARTUP_DELAY_US, that is set to 10 by default. I have reduced this to 1 to get the 9 us speed increase with apparently little change to signal performance.

Does anyone have any hints as to other methods for increasing the speed of the CapSense block?

Since PSoC Creator still requires Windows, I've been trying to get it to run on a Windows 11 on ARM64 installation. I've tried a variety of systems, but I think the problem is that I need native ARM64 drivers for the KitProg2 device. Are they available?

I have a product that uses a CY8C29556, but due to the chip shortage it is not available. For a temporary sub, I've found the CY8C28533, which might work instead. I'm trying to recompile the program written for the CY8C29556 to work on the CY8C28533. The program was written in PSOC 4.4 which doesn't support CY8C28XXX microcontrollers. I've tried downloading PSOC 5.4 and recreating the project, but I get an error

 "addr 0x7fe0 rtcnt 4 MAX 0x4000 !X The compiler has failed an internal consistency check. This may be due to incorrect input or an internal error. Please report the information addr+(rtcnt-2) <= image->size at ..\lksubs.c(175) to "support@imagecraft.com" make: *** [output/Cy8C28533.rom] Error 1"

Is there a version of PSOC or an addon that I can download that supports CY8C28XXX micros and can compile a PSOC 4.4 program?

Hello, I bought a CY8CKIT-046 and working on a project that requires audio file from SD card to be played back. Do you have an example project for the same for this kit? 

I'm using some software enable counters in One Shot mode to create trigger pulses of a specific duration.

I have a situation where I need to trigger a camera array, then move a microscope stage in the Z axis. To accomplish this I'm using an ISR which checks for a Camera ready signal.  the ISR switches the output for a demux and then resets the counter to  generate a pulse.

Because the camera ready signal takes 100us to go false after it is triggered, I also needed to use a second counter to generate a signal to block the ISR from entering prematurely.

While setting this up I discovered a strange issue where the reset pin of the counter is set low, I call the Counter_Start(); function, and the counter is frozen.

One WOULD assume that when you call the Counter_Start(); function on the software enabled counter, that it SHOULD start counting then stop with TC high.  Instead it does nothing, it's not even defaulted to TC high, which would be very helpful for automation.

This cannot be how this counter is intended to work. If it is WHY? The only way I can get the counter to start, is to send a pulse to the reset pin.  This isn't a big deal for the counter reset by a control register from the ISR, I can simply toggle the control register on start up to prime the counter; however, I need to add an or gate and another control register to prime my other one shot counter.

This adds extra complexity and utilizes resources unnecessarily .

Is this something that is being addressed?  A Start() function should "Start" the counter.
