PSoC™ 5, 3 & 1 Forum Discussions
Hi all,
I buying from Farnell a MiniProg3 REV B and i have a big problem of my programmer.
I cant program my devices from 5V. I connect my oscilloscope to SDAT, SCLK and VTARG lines and changing power supply voltage 1.8V to 5V.
Not working from externally power and internally both.
1.8V to 3.3V its ok. The lines follow the voltage. But 5V only follow VTARG. SCLK and SDAT stay on 3.3V. Why?
Sorry for my bad english.
Best regards:

I have both the BLE Pioneer kit and the CY8CKIT-049-42xx PSoC 4 Prototyping Kit. My problem is with the latter:
CY8CKIT-042-BLE Kit 1.0 Rev.*B
CY8CKIT-049-42xx PSoC 4 Prototyping Kit 1.0 Rev.*A
I have a Windows 8.1 Pro system and the version 3.1 SP3 of the Creator software.
I was able to program the CY8CKIT-049-42xx PSoC 4 via a USB cable or by plugging it into a USB port in the front of my computer. After about 6-8 times, however, I started to get the ""Unable to read data from target device" error message while pushing new code in to the kit.
I am detailing all of the steps that I have taken to try and remedy this problem and to date, I cannot get around the issue. I am going to just work with the BLE pioneer kit for now, but it is a shame as I like the smaller kit for quick prototyping.
1. First of all. I thought it was a dirty or unconductive cable so I switched to several known good cables and several known good USB ports on the computer with the same results.
2. I completely removed the USB driver using USBDeview. I then installed the latest "Microsoft Signed Drivers" from the Cypress web site.
3. I then plugged the Kit back in and saw that Windows installed it as Com Port 6 - see screenshots.
4. There are no errors and yellow triangles on the USB driver in the Control Panel
5. When I try to use the USB Host program, I continue to get the "Unable to read data" error message.
6. I opened a brand new kit, as I ordered several and I get the same message.
7. At this point, I think it is a driver issue, but not sure what else to do as I have uninstalled and reinstalled (with clean reboots in between) and nothing seems to make Windows happy.
Attached is a PDF with various screenshots.
Any ideas of other things I can try?
Show LessHi I'm having problems reading a DC high Z signal at the analog opamp ports on the kit while acquiring it for Delsig ADC, I buffered the analog signal in a follower opamp / buffer PGA with no luck so far, what would be the best solution to deal with the high impedance? Will resistors (10M or higher) be enough or I still need an external fA opamp. I'm so far stuck and still unconvinced with the analog specs of PSoC. I'd appreciate your help. Thanks
Show LessHi Is there a way to get -5 or -3.3V out of PSoC5LP Kit powered by USB?

Show LessI am developing one device where i need to turn on LED when signal become high and turn off LED when signal become low .during the LED blinking i have to control the LED light intensity through push up/down botton or (through capsence).
i have attached a jpg of my input signal which is for turn OFF and ON 10 times in 1 sec .
Show LessHi
i want to control my LED intensity by using DAC operation ... would u like to suggest me which way i can control my two parallel connected LEDs .... by voltage or current ? .... is that possible if yes than how .. plzzz
Show LessHello,
I am using the included emfile example project in order to interface with a micro SD card. I am using a micro SD interface board. I have set up the libraries and whatnot according to the provided instructions, connected the card board pins to the correct pins, etc. and I am having trouble getting the example project to work. I have used both a 2GB microSD card, and an 8 GB microSDHC card. In either case, the LCD just shows that it could not format the card, write the directory, write the files, etc. Now, the 2GB card also is not readable on my PC, so I'm guessing that that is faulty. However, the 8GB *did* work on my PC, and it was still giving me the same errors. I probed the lines with a logic analyzer, and there seems to be activity on all the data lines.
Am I missing something? Is there anything else I need to do to get this set up? Does it perhaps not support SDHC cards?

Show Lesshi, can we provide latching through the firmware? How can we do that?
