PSoC™ 5, 3 & 1 Forum Discussions

I run across this problem on some of my PSOC 4 and PSOC 5 designs.  Usually I slightly change the processor clock speed and problem goes away.

I am currently trying to setup a clock for 2 ( 32 bit counters ) and a status register.  The value of the timer would be on the order of 1 khz.  I get a setup warning on the clock.  Not sure what the warning is about and not sure how to systematically solve or handle this warning.

...seriously.  I plan to be in Stuttgart this December 2017.  I just saw Bob's profile in FRG.  So I wonder how far from Stuttgart.  I'd like to thank Bob for much help in the past.  (No, I can't find a contact link under his profile.)

Meanwhile, Bob or others, do you have any suggestions for:

I have a board with a PSOC5 CY8C5268AXI chip that I am trying to communicate with using a miniprog3, I am using external power, SWD communication via the 5-pin connector. I can get it to recognize the chip and connect but then it looses connection and cant find it again without repowering the miniprog3. 

See video of issue here: https://www.youtube.com/watch?v=5I-JARF-0Hs 

I am new to the Cypress PSOC so I don't know what is normal to compare the behavior to.

Hello All!

A "test" program that I'm doing: using a clock-->PWM-->ADC, I'm changing the sample rate of the 12 bit SAR ADC and then reading the results in the debugger (I have a break point in the interrupt - this is triggered when the ADC's eoc signal is high).

I change the clock rate (using 12Hz, 12kHz, and 12MHz), and I apply a constant DC voltage to the ADC pin.  I notice that, when I change the clock signal (which ultimately changes the ADC sampling rate), I get VERY different results.  I'm not sure why this is, and which clock rate produces the "correct" ADC result?

Example: applying 2.0V at the ADC pin with a 12kHz clock (thus giving me a 10 millisec sampling rate) gives an ADC result of 0x1EE

Changing to a 120Hz clock (sampling rate = 1 second) give an ADC result of 0x5A6

What am I missing here?  Shouldn't the ADC results be the same?

I seem to have a problem with creator trying to switch to a different device selection when it goes to program my project.

"Unable to acquire target device PSoC 5LP CY8C5888AX*-LP096" was received while trying to change the selected target.

I don't know why it wants to put an * at the end. CY8C5888AXI-LP096 is my selected device.

I have no problem building a project and writing the hex file using programmer, just the program button in creator.

Error: dbg.M0023: There was an error while programming the device: Connection with device lost during programming. Verify the device is connected and try again.

My target hardware is a Freesoc2 board. Any suggestion how to fix this?

hello,

I have a control register (8 bit wide bus) in my schematic, and I want to take that bus and run it to two places.  the first destination is just a straight connection bit for bit.  for the other destination, I want to send the control register's upper 7 bits to the destinations lower 7 bits (a right shift, effectively) and concatenate a different wire onto the upper input.  

something like:
 

assign destination_reg[7:0] =  {single_bit , control_reg[7:1]}

such that if single_bit is 1, and control_reg was 00110101, that destination_reg[7:0] would be 10011010

what is the best way to do this in the schematic editor?  I don't know how to manipulate the buses well enough.  I could make 7 series-pairs of not gates (effectively a buffer), and assign the inputs to the upper bits of the control_reg bus, then assign the outputs to the lower bits of the destination_reg, but that's really messy.
