Hello, 

I am using PSoC 4 device (CY8C4014LQI-422) for buffering few digital input signals to digital output pins. I am currently using available APIs: Pin_write() and Pin_Read() to assign logic levels. But to understand the delay involved in PSoC response times, I wanted to try writing custom functions for Pin writes and reads in C or Assembly language and program the target PSoC to test for faster response times.

It will be great if someone could review and advise me on the possibility to write custom Pin read and Write functions in  C using PSoC Creator 4.0 / in Assembly language.

Thanks and Regards,

Hello

I'm having read errors that appear to be dependent on the number of bytes being read.  The attachment shows several fram I2C transactions in the same scope capture.  The first transaction does a random read of 28 bytes starting at P0,A 0x00 and the second does a random read P0,A 0x0d.  The read of 28 bytes has several bytes that dont match the same read but of a smaller size.  The errors are consistent 0xBf > 0xA0 (same bits pulled low).  Even if i do the same 28 byte read back to back, both will have the same 0xA0 error.  The voltage of the system is 3.3V, SCLK is 190KHz.

There are multiple I2C devices on the bus

Why does this read fail?

Hi

Is it possible to highlighting all occurrences of a variable (or text item) when it is chosen in PSoC Creator .

Like in other IDEs, when we double a click on a word, all other occurrences are highlighted.

thanks

Hi!

My plan is to implement the following startup sequence from cold reset:

1. CM0p executes and starts CM4 (basically default functionality)
2. Bootloader application 0 starts. This has the responsibility to select which of applications 1 or 2 to execute

Is there a way, using the DFU SDK, to persistently mark an application as next/current, Linux style? With factory defaults it would contain app 0 and at least one of app 1 and 2. Powering it up the first time in post production it would boot either app 1 or 2. At a later point in time this app installs another app in the free slot. A switch is performed to the new app. How can I persist this value so that the new application is executed on subsequent cold resets?

Thanks!

Hello

to everybody.

I'm developing product using  CYW954907AEVAL1F

Have I to buy my MAC address and VID ?

Hello.

I purchased the CYUSBS236 kit.

I'm trying to read/write my target slave device thru SPI using the tool.

Only utility provided with the tool is the configuration and also test utility.

Is there any GUI utility that I could use on Windows based to try to read/write any target device thru SPI/I2C..?

I can't find yet.

Thank you.

Hey to all,

I have a problem with my RS485 TX EN signal. The TX_EN Signal does not have a fixed length.

That means after the message the signal does not stop right away. I found another user in this forum who had the same issue nearly 2 years ago but the final solution was not in the topic.

Can anyone help me with this problem?

@YatheeshD_36  was the one who helped in the other topic.

Thanks in advance,

Goodmorning,

We're using the device Am79C973 "PCnet™-FAST III Single-Chip 10/100 Mbps PCI Ethernet Controller with Integrated PHY". We have different lots of this device, and by interrogating their ID registers via JTAG, they differ by bit 30 and 29.

We consulted its Datasheet (in Attachment), and as we understood based on Table 18, they states the version of the device (bit 31-28).

We have devices with bit 31-28 equals to 0100 and 0010.

We can't find any info of what is the difference based on the version, can You provide those information for us?

Thank you.
