PSoC™ 5, 3 & 1 Forum Discussions

The schematic shows that the USB Micro-B receptacle shield should be connected to the board's GND by way of a 100K resistor and 0.01uF capacitor in parallel. All my copies have no solder in the receptacle mounting holes that would make this connection. Once I add solder myself the components test present.

It doesn't make much difference because 3 of the 4 USB cables I tested don't have a shield.

I'm trying to determine if the RC connection is best, or direct connection of the shield to GND is better. Both are recommended by skilled designers. I haven't seen anyone recommend open-circuit.

Hi there!

I've got 2 old cy8ckit-001 boards and don't know their revision (A,B,C?). 

Board is pdcr-9461 rev5 (text on label is 121R-46100)

I'm interesting is it compatible with last PSOC5 kits as CY8CKIT-010?

And maybe there are still exist a way to "update" a revision of my PSOC3 cy8ckit-009 ( to "release"-revision mcu) for free.  

Hello,

I was trying to teach myself how to use CapSense using the CY8CKIT-001 and can't even get the tuner helper to connect, I keep getting the error message shown in the subject line. I set up my pins as shown in http://www.cypress.com/file/46756/download, page 5 for the PSoC3 module, which I'm using at the moment. I note that this uses the MiniProg3 but looking at the PSoC3 module's schematic, the MiniProg3 connects to J5 TDO, TDI and TCK but the CapSense Tuner is set to use the MiniProg3 I2C link (my pins are set to P12[5:4] as indicated by the module's schematic).

The CapSense data sheet covering the Tuner GUI User Guide shows a very simple procedure for accessing CapSense data that I can't get to work. I've checked my parameters a number of times and they align between the settings shown in the CapSense Tuner configuration window and that shown for the PSoC components.

Any suggestions?

Hello,

I am a fairly new user of the PSOC and have been working with the 049-42xx kit. The project I want to build consists of an external ADC sending data to the PSOC SPI master component and relaying that through the UART to the USB-serial bridge card edge connector into a PC. I put myself into a jam by already creating a PCB for the project with the dev board on top of the PCB.

I later realized I couldn't get the PSOC 4 UART to transmit data fast enough or store enough data in a buffer in SRAM (4kB) - and has no DMA channels to do these fast transfers. My current solution is to switch to a PSOC 5 which has 64kB of SRAM and DMA channels. However, since the pinout is different with a larger spacing between target board and KitProg, I am investigating suitable workarounds. A .png is attached showing a somewhat to scale comparison of the two kits with the spacing difference indicated by blue lines.

I am using MATLAB to collect the data on a PCB and am more comfortable interfacing with usb-serial communications compared to using a USBFS component.

I have had many ideas so far so bear with me (all involve some pins on the target board not being connected to the PCB):

1) Snap the KitProg off and place it above the target board horizontally overlapping to achieve proper pinout spacing. Though the pinout of the usb-serial bridge vs KitProg has the GND and VDD in different locations ( and I foolishly connected them to PCB)

2) Snap the KitProg off and replace with a USB-serial bridge from the 049-42xx kit connecting that to target board. Might not be feasible given the different interconnect traces e.g. SWDIO and SWDCLK vs RX and TX

3)Snap off KitProg and use it once in a while to program but use the USB micro connector for data output. However, I am unsure if I can use the USB UART component with the micro connector or only the USBFS component.

I was wondering if I could get some advice and thoughts on these options or any others that might be more feasible.

Sorry for the length of the post and thank you in advance for any help,

Scott

Hello Every Body,

I am using two dithering VDAC having same clocks. Now the problem is, one dithering VDAC is generating correct voltage but the other is not.

Please see pic attached.

Looking forward for your reply.
