I note a gap between each byte in an array being sent over SPI (using 5LP SPIM component). Is there a way to prevent this? I assume that it is caused by software polling to see when byte has been… Show more

Hello everyone, I have recently come across PSoC 5LP. I am working on a project where I have to generate three frequencies to run the TCD1304DG CCD. The three frequencies are Master Clock (2 Mhz),… Show more
So here's something I mocked up, but haven't tested: Do be careful with the LUT as it normally would be backwards for a down counter (click on the input hex value twice to sort in reverse order).…
Dear community, As already discussed in DMA Wizard prohibits linking 8-bit SAR ADC to 8-bit VDAC there is an option to change the DMA capability file of the SAR ADC to obtain 1 byte burst. With… Show more
/odissey1, That clarifies a lot! Quite logical explanation, so thank you for explaining. My application is to develop a bidirectional optimal trajectory control algorithm for a series-resonant…
Hello, I am trying to connect a terminal (TerraTerm) to my PSoC 5LP kit(CY8CKIT-050) so I could print something out to a terminal. With my PSoC4 kit, I would just use a UART SCB component for… Show more
Thank you very much! Apparently my USB to RS232 cable doesn't work. I will run the test when I get a new cable Thank you!
I have a PSoC5LP application which includes bootloader and bootloadable components. On power-up, the bootloader checks the state of a pushbutton. If the pushbutton is pressed, it enters the boot… Show more
I have found a solution to my problem. It appears to be linked to the way I am generating the 5 second delay in my PC program, and the period of the delay. I was using a thread.Sleep(5000);…
Hello, I want to create a .txt file and save it on my sd card. I using the emfile component and use his example project. I using a PSOC 5LP097 KitProg: CY8C5868LTI,a screen, a Micro-SD card… Show more
Can you please elaborate the requirement. Do you want to write new line into the text file? Thanks, Hima
I am currently working on a project that controls an external device using SPI. When I attempt to write data to some locations in the external SPI device and read them back, the program locks up… Show more
I am a bit confused regarding use of the flags when sending SPI data and seem to get back wrong data from my device I have a SPIM component set up and started and can see activity on CS, Miso,… Show more
Isn't the communication synchronous, RX data is clocked in AS the TX data is going out. So if 1 byte is being sent at a time, the next byte is already received once the tx byte has gone?
I have a calling routine (read32reg) that passes a readBuffer to routine (readfromspi). In the readfrom spi routine I do receive correct data (4 bytes) from the device. However, when I pass the array… Show more
Thanks for that. I did eventually find it last night and it fixed the issue.
I would like to measure temperature on my system using a thermistor. Can I connect the Vhi and Vlow to Vdd and '0' internally on PSOC to save two GPIO? If yes, how it will affect the measurements… Show more
I would not connect the Thermistor to power all the time because it will self heat and introduce an inaccuracy in your measurement. In my project, I fed it with a VDAC so I could set the voltage to…
I have an i/o pin of the PSOC 5LP connected to a microcontroller output pin: 1. Imagine that I want to set the pin of the PSOC as if it was "physically" disconnected to the microcontroller output… Show more
Well, provided the other chip supports it, you could set the pin to be open drain, drives low, and tie the line high via resistor. Something like: Where the pin is doing this: I think…
We are using PSoC Creator 4.1 and converted our test application to bootloadable. When we flash over JTAG either app_1.hex or app_2.hex the bootloader checksum verification fails for both apps.… Show more
When I call the Bootloader_Exit() API it works as I would have expected. App_1.hex will boot when Bootloader_EXIT_TO_BTLDB_1 is used, and not boot when Bootloader_EXIT_TO_BTLDB_2 is used. App_2.hex…
Hi Team, I am using PSOC5 development board, My requirement is to read 40 pins status continuously, Which method is to best to read 40 pins status ? The PSOC5 board support 40 interrupt ? If… Show more
Hi naveenkumar.p_4018846, As suggested by user_342122993, there are different ways to achieve this., But it is better if you achieve this using interrupts as you won't waste CPU time by…
Hi all, I've got some questions regarding a specific ADC+DMA setup I'd like to accomplish, but I'm not sure how to make it happen (I'm rather new to using DMA). I'd like to, through DMA, have the… Show more

I was having problems with the onboard programmer disappearing from my Windows device manager. So at some point PSOC creator informed my I needed to upgrade the firmware on my Cy8ckit-059 PSOC… Show more
I think you have corrupted the Kitprog. Please restore it to factory settings as mentioned in page#46 of the Kitprog user guide present in the path: "%Install-Dir%/CY8CKIT-059/1.0/Documents/" and…
Hello, I have problems with the following code, writing and reading data to the EEPROM. I always get not the same read back as I was written to the EEPROM. I have created a project based on the… Show more
Thanks Odissey1, I have tried this component with the same result. There is still a warning with your component during initializing, I have used Creator 4.2. I have the project attached, please…
We've just released a product that is field upgradable so it consists of a Bootloader and a single Bootloadable. It was developed using Creator 4.1. We are now moving to Creator 4.2 and I notice… Show more
LinglingG_46, Unfortunately the reply isn't very helpful. I would like specific answers to my situation. Also your statement about newer component versions being compatible is NOT always the case! …
