PSoC™ 5, 3 & 1 Forum Discussions

I took my Kit-059 and reprogrammed the KitProg to MY application using the KitProg bootloader.  That works!.  

However when I try to reprogram the KitProg back to PSoC 5LP Factory Program Restore, it does not return to KitProg program/debug functionality with a PSoC target PCB.

I followed the instructions for both the "8.2.1.1 Restore PSoC 5LP Factory Program Using PSoC Programmer"  and  "8.2.1.2 Restore PSoC 5LP Factory Program Using Bootloader Host Tool".  In both cases, the bootloadable firmware indicated successful programming and verification.  However, once completed, the KitPRog would not be recognized by Creator or Programmer as a programming or debugging device.

The KitProg does not show up in Device Manager.

I can successfully reload my application into the KitProg bootloader and it appears to respond correctly.

Without better evidence, once I program the factory KitProg back in, the PNP parameters of VID = 04B4 and PID = F139 do not show up.  I do know that the USB interface on the KitProg is working because I use it for my bootloaded application.

I have a CY8C24794-24LFXI chip that I plan on reading and writing a program to, and it's not clear to me on how to accomplish that based on what seen from the Cypress product line/

As I understand it, the CY3217-MiniProg1 interfaces with my PC, and it is plugged into a 4 pin header on the CY3214-PSoCEvalUSB PSoC CapSensePLUS. From there I should be able to use the provided software to interface with a CY8C24794-24LFXI PSoC.

What I don't understand is how I connect the PSoC to the development/prototyping board. From the screenshot here, it looks as though there is a PSoC soldered directly onto the development board. What I need to be able to do is to connect a CY8C24794-24LFXI to the MiniProg1, write or read it's data, then disconnect and solder to my PCB. How can I accomplish this? Is there a socket or breakout board I need to use? Is there a socket on the development board I don't know about? I honestly won't need a full prototyping or development kit, I really just need a way to read and write to the chip.

I'd appreciate any insight into how to use these tools, thank you!

The maximum packet size of the endpoint is 64 bytes in the CDC interface of the USBFS component. If the received data may exceed 64 bytes, is it impossible to process the data received by the endpoint interrupt? Is it necessary to process the receive buffer by polling if the receive string exceeds 64 bytes?

Hi,

We would like to confirm the rewriting of NVL.

It is necessary to set GPIO low after POR.

Therefore, We set the reset tab of Configure 'Pin' to "Pulled-Down" and wrote the program.

GPIO goes low after POR as expected.

We know that NVL has a rewrite endurance value.

Endurance of Non-volatile Latches (NVL) in PSoC 3/5

In order not to rewrite the information of the NVL set in the pull-down,
When overwriting, it was set the reset tab of Cofigure 'Pin' to "Don't Care".

Operation was confirmed after setting to "Don't Care".
Then it looks like the pin is set to Hi-Z. Not Low.

Should we always write with the Configure 'Pin' settings "Pulled-Down"?

If it is necessary to always write using "Pull-Down" settings, does the rewrite endurance value always decrease every time?

We were aware that the "Don't Care" setting did not rewrite the NVL information, but it seems to be different when we confirm for the pin operation.

Regards,

Hi there,

i am using current sensor (LSTR) that translate current into voltage, most of the reading is between 2.5 - 3.125 , how can i adjust the ADC range to be between  2.5 - 3.125 ?

thank's

hi

I can not use the same hex file for programming Cy8c5666 and cy8c5667

do you know a solution for the issue. the customer what ONLY one file for programming
