PSoC™ 5, 3 & 1 Forum Discussions

Hi,

We are considering USB HID Bootloader for PSoC5LP.

Browse AN73503 and use USBBootloaderHost_VC2015.zip.

However, sometimes writing fails.
The USB HID bootloader host app stops halfway due to error code 0x04 (data is not in the correct format).

When analyzing the USB HID host application software,

1. Send data to the device
2. Query device for response

The above 1 and 2 are repeated.

Since 1 and 2 are executed in succession,

We thought that if I made an inquiry without being able to return a response, We would not be able to read the response correctly.

Therefore, when a wait (10ms) is inserted between 1 and 2, it is operating normally. Write failures no longer occur.

As a method, wait time of 10 milliseconds is inserted with System.Threading.Thread.Sleep (10) before using ReadInput () of CyHidDevice class.

Is this workaround correct?
Or do you know any other good workarounds?

Regards,

Hi,

We would like to confirm for the “Serial Number String” of the USB component.

The USB serial number string is the “User Call Back” option.
The serial number of the product is registered using USBFS_SerialNumString () API.

Processing is performed as follows.
/***********************************************************************/
USBFS_SerialNumString ()
  USBUART_Start (0, USBUART_DWR_VDDD_OPERATION);
If (USBUART_IsConfigurationChanged ())
  {
  While (USBUART_GetConfiguration () == 0);
  USBUART_IsConfigurationChanged ();
USBUART_CDC_Init ();
}
/***********************************************************************/

The serial number string is set with 9 characters, but the serial number string is not set correctly.

When CyDelay () is inserted between USBUART_Start () and USBUART_IsConfigurationChanged (),

the serial number string seems to be set normally.(Delay time is about 300ms)

Even if the settings are the same (source code),
The serial number can be set, sometimes it cannot, and the operation is unstable

When setting the serial number string, are there any problems with the procedure described above?
Could you tell us about the correct usage of the USBFS_SerialNumString () API?
(Component start timing and API usage timing, etc.)

Regards,

Hi alll,

i am usings  psoc 5lp for generating waves from Wavedac8 using arbitrary file and change samples value in code . I want to use 500 samples and wavedac8 take only 250 samples even maximum range of dac is 4000 . Whenever I use more samplesthan 250 it's not generate any wave can any one help out?

hi,

i have a technical question about RTC component in CY8CKIT-059.2020 is the leap year and i set time to 2019/12/31,23:59:55.when it runs to 2020/1/1,0:0:0,the bit RTC_STATUS_LY which is contained in status register will go high when the current year is a leap year,but when i set time to 2020/2/28,23:59:55 and let it run,not only the bit RTC_STATUS_LY won't go high but also the date isn't 2020/2/29.

I am using PSoC 5LP and need to implement LVI (low voltage interrupt).

LVI has IRQ#-0, but in Creator IRQ#-0 is already used by UART-ISR which I cannot change. There is no component for LVI/LVD.

How can I implement LVI and trigger ISR when voltage goes low?

Thanks.

Please answer below.
The same question is written in English and Japanese.

・English
There is a CapSense pin ①②.
If CapSense pin① is sensing, is CapSense pin② GND? Or is it Analog Hi-Z?

・Japanese
CapSenseピン①②がある場合、
CapSenseピン①がセンシング中、
CapSenseピン②はGNDでしょうか？もしくはAnalog Hi-Zでしょうか？

Hello

which pins to choose for my project
i have:
CY8C5888LTQ MCU

1x differential Delta sigma ADC 18Bit  with internal vref 1.024
1x diferential SAR adc 12bit  with internal -/+ vref 1.024

In  AN58304 (PSoC 3 and PSoC 5LP Pin Selection for Analog Designs)

the document says:

Of these seven ports, three have a slight analog performance advantage P0[7:0], P3[7:0], and P4[7:0]. These ports reside in the analog upper portion of the chip. The analog globals, AGL[7:4] and AGR[7:4] that connect to these ports, also reside only in the upper analog section of the part, which give these ports a slight signal-to-noise ratio advantage.

Now i configure pin to next ports and analog rail:

1. for best accuracy my pin  position correct  or  can I find a better solution for high accuracy?

2. for best accuracy i need use bypass capasitors 10uF   for  all extRef pin or  only  for selected bypas capasitor port  in deltaSig component  ?  

      I am using seven segment multiplexer(8 digits )and capsense at cy8c21434 controller.   I cant  use 7 segment user module. because  not able to provide separate port pin   . so i m create 2 ms timer interrupt to operate 7 segment multiplexer.   Also my application has capsense switches(5 number). when i use any one (7 seg or capsense)  means it working well.   But i try to use 7 seg and capsensese at one controller means it disturb each other module (capsense sensing issue, 7 seg flickering ) .  So how can i over come this same issue..  any one help me.....
