Investigating 16 Bit Filter Operation Example Project(https://www.hackster.io/bmah/psoc-5lp-16-bit-and-24-bit-digital-filter-code-examples-ddcf9c),

I discovered a strange anomaly.

Everything works fine, until you change from channel A to Filter channel B. Almost in all input signal range, the output filter signal is dramatically distored like an overload in the middle of scale. Here are some pictures. First pic. - Ch. B, second one - Ch. A. Yellow - Input, Blue - Output.

In the same time corresponding 8 and 24 bit examples works fine on both channels.

Modified project in attach. To choose between Flter Channels comment/uncomment #define FiltA at the beginning of main.c.

Hi, its possible programmer the CYBLE-022001-00 with this kit programmer CY8CKIT-059?

I have several CY8CKIT-059 boards that I have been trying to use with external power, other than that supplied through the USB cable connected to the KitProg.  I need to use a heftier power supply than what can be supplied through the KitProg or the USB cable at the far end of the board.  It's because of the number and type of devices I have attached to the board, mainly (4x20 LCD display w/backlight, DS3231 RTC module, ENC28J60 chip for an ethernet connection, for now).  The attached devices really suck too much juice for me to run through the USB connection.

What I am running into is a problem with programming through the KitProg, while powering the board externally.  I know about removing D1 on the KitProg board to prevent power from backfeeding to the KitProg, but that introduced a new problem.  Once I remove D1, I can't program the 5LP at all, or even see it through the Bridge Control Program.  That's been also tried with a second USB cable connected to the far end of the board, which does power it up.  If I put D1 back, then it works, but with D1 out, it won't program.

I've tried running 5V power to VDD on the main board.  I've tried through the target USB connector, per section 4.2.3 of the manual.  I suppose that I could just power all of the external devices using external power, but I'm not thrilled with the idea that power might backfeed through the IO pins.

I'm open to suggestion.

Again, if D1 is removed then I can't do diddly, programming-wise.  I have NOT snapped the boards apart, mostly because I don't want to track down programming boards (I tend to lose them until I find 6 at a time, just after ordering more)

If I supply power through the target USB connector, the 5LP chip seems to get a bit warm, which also makes me nervous.  And that's with D1 removed.

Hello,

We are intended to place capsense slider segments in curved shape  ( as shown in attached file ) and have below queries.

1> Is there any guideline document available to place slider segment along curved path ?

2> Is it must to have all slider segments in equal dimension ?

3> Is there any requirement on width of the ground mesh around slider segment ? As we intend to place slider close to board edge, and have very small room for ground mesh on one side.

4> Can slider trace run parallel with 10 mil clearance in between ( No ground mesh in between them) ?

5> is it Ok to place capsense IC on one side of slider , as shown in image ?

Thanks,

Vishal

Hi There

I would appreciate if someone from where I can get this info ,because  opamp 1.90 only give that info for Psoc 3.

Thanks in advance.

Hi!

I want to program CY8CMBR3110 with the Arduino IDE or similar.

The 128-position EZclick-generated programming matrix:  Ex: ... .0x78u, 0x00u, 0x00u, 0x00u, 0x00u, 0x00u, 0x00u, 0x00u, 0x00u, 0x00u, 0x00u, 0x00u, 0x7u, 0x7Fu, 0x7Fu, 0x7Fu, 0x80u, 0x80u ....  I want to know who the recorder is for each array position above, since I want to program for low power consumption like look-for-proximity
