PSoC™ 5, 3 & 1 Forum Discussions
I have developed a board using a CY8C5488AXI-LP120 psoc. I have an SPI host module set up in it to interface with a Micrel (now Microchip)
KSZ8851SNL Ethernet controller IC (which includes MAC and PHY layer functionality). At this time I only have to verify that the hardware is working. A full TCP/IP stack development will come later on. For the hardware test I believe that I only would need to return a ping packet initiated from a local network computer. Does anyone have experience with this Ethernet controller that can suggest how to set up the SPI for communication compatibility?
Show LessHi all,
I'm attempting to use a PSOC 5LP to read data from a SHT75 Temperature & Humidity sensor (https://www.sensirion.com/en/environmental-sensors/humidity-sensors/pintype-digital-humidity-sensors/).
In order to read data from the sensor, I need two pins (clock and data). At the moment, I configured my clock pin as a Digital Output (Strong Drive), and my data pin as a Bidirectional Pin (Open Drain Drives Low). The clock pin is working fine with the functions I created, while the data pin is not working as expected: do I need to dynamically change the configuration of the data pin whenever I need to write/read from it? How should I connect the bidirectional pin (pull-up resistor?)?
Thanks,
Davide
Show LessI was wondering if it's possible to re-program the CY8CKIT-059 Kitprog on-board Programmer?
I've looked at the schematic in the 'Kit Guide' datasheet (page 38) and I can't see any programming pins routed out.
Many thanks

Show LessHello
i am trying to design my own customized board kit depending on CY8CKIT-050 Board , i already downloaded files Schematic, Layout, Gerber, BOM attached in
http://www.cypress.com/documentation/development-kitsboards/cy8ckit-050-psoc-5lp-development-kit
i tried to open them in Eagle and Altium but they told me files are corrupted
please can you help me with that.
Show LessIs there a way to read Vddd and Vdda without using extra analog pins (and voltage divider)?
Running on power boost, and just need to monitor actual system voltages.
Thanks
Show LessIs it safe to use negedge clocking in PSOC Verilog. I was concerned because AN82250 PSoC® 3 PSoC 4 and PSoC 5LP Implementing Programmable Logic Designs with Verilog, on page 13 says:
Note To reduce the likelihood of timing and synchronization failures, it is preferable to use posedge clocking in PSoC designs.
But no further detail on why the AppNote says this. On the other The Warp Verilog Reference Guide doesn't seem to mention anything against negedge, and uses it in several examples.
When designing for DDR style clocking from an external source, using both posedge and negedge clocks seem needed (or to resort to a significant oversampling using an internal clock.) Is it reasonable to ignore AN882250's advice in this case, doing something like:
always @ (posedge clock)
begin
. . . something
end
always @ (negedge clock)
begin
. . . something else
end
?

Show Less?What are the minimum requirements to program CY8C27443-24PXI AND CY8C29466-24PXI?
Hello,
I'm a PSoC beginner and I need to apply a math function to each sample converted by an ADC in order to have a certain result on the output of a VDAC. This needs to be applied considering that the value of the samples is read in Volts.
I'm using an ADC DelSig with 16 bits and I'm only transferring the 12 MSB to a DVDAC with 12-bit resolution through DMA. Also, I'm using an oscilloscope to analyze the results.
Basically, the question is: is there any way to access each sample, modify its value and then transfer it to the VDAC?
Thank you
Show LessAs we are developing a measuring instrument we have selected CY8C27443-24PXI AND CY8C29466 -PXI .WHICH TOOLS ARE REQUIRED TO PROGRAM THESE TWO PSoC ?
