Hi,

I'm trying to create a PSoC 58LP888 project with a parallel asynchronous input.

The host will signal on CS* and transfer 9 data bits  on the rising edge of WE*. 

I need to transfer these 9 data bits to memory using a DMA.

It seems to be pretty easy if you only want to use 8 bits. Just configure component cy_pins_v2_20 as an  8 bit wide input  pin called "Parallel_Input". Under mapping, ensure "Contiguous" is selected and use the following in the DMA config:

CyDmaTdSetAddress(dmaTD[0], LO16((uint32)&Parallel_Input_PS), ...

Parallel_input_PS is defined in Generated_Source/PSoC5/Parallel_Input/Parallel_input.c

However, you can't use this technique with anything greater than a 9 bit input port. As soon as you go greater than 8 bits, the contiguous box must be unchecked and the .c and .h files disappear fropm the gerenated source.

I can't find any other 16 bit component that I can connect to GPIO pins and use to DMA into memory.

How can I get over this simple hurdle? I know the DMA can handle 16 bit wide transfers, it should be "just" a matter of getting the data from the IO pins into a 16 bit wide *thing* that I can point the DMA at.

Thing is, I'm "just" stumped!

Any ideas please?

Hello, I am using CY8CKIT-059 prototyping kit and I am trying to use sw3 to switch my channel using analog mux. The attachment is my project. The code is working well with sw1 but when I change to sw3, the switch didn't work well as it stuck at chan 0 ( there's chan 0 and chan 1 in the project). Is there any problem with my code?

I am trying to capture a stream of bits into a buffer using a PSOC5LP board.  I would like to capture roughly 40 bytes each burst at 8MHz.

This seems like a great job for a shift register and DMA.  

Apparently shift registers output to a FIFO which needs to be triggered by accessing a status register before the output will update properly.  Has anyone used a shift register and DMA like this before?  How do you access the appropriate registers and is it possible to use a 32-bit wide shift register?

I will upload a sample project tomorrow (I have run out of work day now)

Thanks

Hello,

we are currently developing on a PSoC 5LP and while searching for PGA's tolerances we found out that there are 2 different values for what should be the same PGA. This values can be found in:

- Programmable Gain Amplifier (PGA) (infineon.com) on page 13

- PSoC® 5LP: CY8C58LP Family Datasheet Programmable System-on-Chip (PSoC®) (infineon.com) on page 108

We were wondering which value should we use, are they from different PGA? Maybe one of them refers to ADC buffer

Thank you in advance,

David

Hi,

I have:

• CY8CKIT-050 Kit  (it is a 5LP)
• MiniProg4

I can program the 5LP with the MiniProg4 in Reset mode only when it is externally-powered.

But it fails if it is only powered by the MiniProg4.

I'm using latest PSoC Programmer with latest firmware for the MIniProg.

• PSoC Programmer v3.29.1
• MiniProg4 fw version: 2.21.1005

Attached  is the image of the error and the how I'm configuring the PSoC programmer.

Any idea why it could be failing? Many thanks

I have an analog signal that is coming into my PSOC, I want to amplify (like with a PGA) it and output it but only when a digital hardware signal is high. 

I thought I might be able to do this with an analog mux that switches between my signal and a constant Vref, but the software complains that the mux is connected to the PGA. 

I get an error like "Net_2368 is expected to only one GPIO analog pin but instead if connects to "\PGA:SC\". please fix th econnection.

is there any way for me to control or gate the analog signal using a digital signal?

this would be fairly easy in firmware, but the firmware cannot react fast enough so I need the digital signal to remain a hardware-only signal.

Hi, I am using CY8CKIT-059 prototyping kit and I tried to create a single differential circuit which connect multiple inputs on analog mux to a single op amp. I want to switch the chosen input on the analog mux using sw1 switch. Is this possible and how to do it? the attachment is my project. Thank you

Hello,

I have a project with a SPI Slave and can't seem to transmit more than 4 bytes. The SPI master receives the first 4 bytes correctly but any further bytes are always the same as the first byte transmitted from the slave.

Global interrupts are enabled and Tx/Rx buffer sizes are set to 64 bytes.

Slave code is as below:

//***********************************************

CyGlobalIntEnable;

SPIS_Start();

SPIS_WriteTxData(0x22u);
SPIS_WriteTxData(0x33u);
SPIS_WriteTxData(0x44u);
SPIS_WriteTxData(0x55u);
SPIS_WriteTxData(0x66u);
SPIS_WriteTxData(0x77u);
SPIS_WriteTxData(0x88u);

while(1u)
{
     CyDelay(100);
}

//*******************************************

SPI Master receives 0x22, 0x33, 0x44, 0x55, 0x22, 0x22,0x22

No matter what I try I cannot send more than 4 bytes correctly. Tx interrupt seems to be firing  ( CY_ISR(SPIS_TX_ISR)  )

and software buffer is enabled.

Any help much appreciated

Hi all,

I am using CY8Ckit-059 and I need to log some data in the SD card with real-time reading using the internal PSOC RTC component. 
so the data logs will be like  

Timestamp: data1: data2: data3............................

For that Purpose, I was trying the RTC  example and printing the timestamp on the USB-UART serial monitor.

In the example code  I am trying to printing the tmpVar on the serial monitor after evey 5-10 seconds, and it is giving the same value that was assigned initially. 

tmpVar = RTC_ReadSecond();
PrintDecNumber(tmpVar);
tmpVar = RTC_ReadMinute();
PrintDecNumber(tmpVar);
tmpVar = RTC_ReadHour();
PrintDecNumber(tmpVar);

tmpVar = RTC_ReadDayOfMonth();
PrintDecNumber(tmpVar);

/* Get and print month */
tmpVar = RTC_ReadMonth();
PrintDecNumber(tmpVar);

/* Get and print year */
tmpVar = (uint8)(RTC_ReadYear() % 100u);
PrintDecNumber(tmpVar);

/* Get and print day of week */
tmpVar = RTC_currentTimeDate.DayOfWeek;
USBUART_PutChar(tmpVar + 0x30u);

can anybody please help regarding this?

If any example is available please share.
