running the sample program as indicated in : AN75320
Starting MAKE...
Hello everyone..!
I have Windows 7 and on i want to build my program on the electronic card i got a error
okay .. on i click on Debug -> Program some window call's "select debug targat" i see ther card call's "PSoC3" on "FirstTouch"
on i clicking on the "PSoC3" i got a message on the right "this device was recognized. but PSOC creator does not support it at this time"
and on i put the "hand" on the "PSoC3" i see message : "this target device is already in use by another client"
Sorry about my bad english .. Thank you !! 🙂
Show LessHello everybody,
this is my first interaction in the community. I'm looking forward to be a part of this community.
So, this is my Question:
At the moment I work on a Cypress Controller Board (Like mbed) to control other Applications with CY8C5868AXI-LP035. And I have a question about the power supply from my 5LP Development Board. In this board they route from the USB port to the VIN and VOUT of the LDO. What is the reason? Could I not simply route from USB to VOUT pin to supply the design?
Sorry for my bad english!
Best regards,
Florian
Show LessHi every one!!!
Can anyone help me with this code, please?
I'm learning to use SPI and Shift register components.
I sending 4 bytes via SPI to the Shift Register.
Theoretically each "Store pulse" at Shift Register store input, each byte is stored in FIFO out.
This does not happen. With the C code which attached, the LCD display reads @ @ @ @ instead 0x0a, 0x0b, 0x0c, 0x0d that I am sending.
This is a very trivial code, but I could send data to any port in this way.
I am using the function "ShiftReg_readData ()" to capture the bytes of FIFO out.
Is this correct? The document number 001-85014 Rev A it seems to me something confuse with
"ShiftReg_readData ()" Function.
I hope you can understand what is written, because I do not speak good English.
From already, thank you very much to anyone who can help me.

We are using the PSoC™ Automotive Multitouch All-points Touchscreen Controller CY8CTMA140 IC for a device. I can't found any sample driver (WINCE/Linux/Android) to program and use the controller. Can somebody help/guide me to find some sample driver?
Thanks in Advance,

Show LessHi,
To estimate the minimum sampling frequency that could be used for S/H (Sample and Hold) module in PSoC 3/5,
we need to know the droop rate of the S/H circuit. Droop rate of the S/H circuit
refers to the rate at which the voltage across the hold capacitor(inside the S/H)
drops with respect to time in hold mode.However, the droop rate of the S/H module is not characterized.
I have attached two projects “sample_hold_test” and “sample_SH” that can be used for estimating the maximum hold time and minimum sample speed for 10% voltage droop respectively.
The same projects could be reused by minor modifications in the firmware for different voltage tolerances.
All the tests were done on CY8CKIT-030 PSoC3 DVK.
I hope this would help for those looking for S/H droop rate.
