PSoC™ 5, 3 & 1 Forum Discussions

Hi, I would like to know how to display the menu bar of psoc designer 5.4. Accidentally delete it and can't appear. I tried uninstalling and installing again and it does not appear

Help me 🙂

hello,

i have attached project . I tried ti read potentiometer by ADC and use DMA to trasfer the adc data to Vdac.Also i have used usrt to print the value of adc. After each conversion of adc DMA should update the vdac but that dint happen. I believe i went wrong in configuring DMA.

Can DMA and UART access the same component at same time?

I Just wanted to know where have i gone wrong in configuring DMA. I used DMA wizard.

Thank You.

Hi,

I want to know how Linked mailbox for CAN module works for rx frames and how i can process mailbox by polling method ?

I have a simple Bootloader test program that shows the generated code for the 5LP gets stuck once the 64 char SW FIFO gets full (Write index = 63, Read index = 0).

For some reason, the  UART code seems to stop pulling from the FIFO. It gets stuck in UART1_PutChar() at line 1067 of .\Generated_Source\PSoC5\UART1.c :

        do         { /* Block if software buffer is full, so we don't overwrite. */          #if ((UART1_TX_BUFFER_SIZE > UART1_MAX_BYTE_VALUE) && (CY_PSOC3))             /* Disable TX interrupt to protect variables from modification */             UART1_DisableTxInt();         #endif /* (UART1_TX_BUFFER_SIZE > UART1_MAX_BYTE_VALUE) && (CY_PSOC3) */              locTxBufferWrite = UART1_txBufferWrite;             locTxBufferRead  = UART1_txBufferRead;          #if ((UART1_TX_BUFFER_SIZE > UART1_MAX_BYTE_VALUE) && (CY_PSOC3))             /* Enable interrupt to continue transmission */             UART1_EnableTxInt();         #endif /* (UART1_TX_BUFFER_SIZE > UART1_MAX_BYTE_VALUE) && (CY_PSOC3) */         } -->     while( (locTxBufferWrite < locTxBufferRead) ? (locTxBufferWrite == (locTxBufferRead - 1u)) :                                 ((locTxBufferWrite - locTxBufferRead) ==                                 (uint8)(UART1_TX_BUFFER_SIZE - 1u)) ); 

All I see are the first 2 chars ("..") on my terminal before everything stops in this simple test setup to reproduce the problem on my CY8CKIT-058 board:

#include <project.h>  int main() {     UART1_CyBtldrCommStart();           // Starts the communication interface and enables its interrupts & callbacks          char str[] = ".";            //"\r\nThis is a sample string.";     uint16 written = 0;     cystatus ret = CYRET_SUCCESS;     for (uint16 loopCount = 0; ret == CYRET_SUCCESS; loopCount++)     {         Pin_User_LED_Write(loopCount & 1);         //UART1_PutChar('.');         ret = UART1_CyBtldrCommWrite((uint8 *)str, sizeof(str), &written, 0);         //CyDelay(10 * UART1_BL_CHK_DELAY_MS);                   <----- this keeps it from getting stuck at a full FIFO     }  }

Anybody should be able to reproduce this with PSoC Creator 4.0, a CY8CKIT-059, a simple project with only a Bootloader component (mine is set for Dual-application mode) and a UART component, and the main() of main.c I pasted above. Can anybody explain why that's happening before I cry "BUG!!!" ?
 

EDIT: I figured it out, I should have been calling U1RX_ISR_Start() to properly enable the interrupt rather than calling U1RX_ISR_Enable() alone.

Hi all,

I'm getting started for the first time with using a PSoC 5 (CY8C5668AXI-LP010) and I've got a question about setting up a UART Receive interrupt.

I have the UART present and functional (I.E. UART1_PutString works, so the module is operating) but I'm having a tough time getting the interrupt upon receiving a byte to work correctly.

I currently have the UART module placed and wired.  the rx_interrupt signal is wired to an interrupt named U1RX_ISR. This interrupt is of type "Derived".  The UART is configured to interrupt on byte received.  The buffer sizes for both RX and TX are 4 bytes.  In the code, I am enabling U1RX interrupt via the U1RX_ISR_Enable() function.  What I am now finding is that sending a character to the UART from my PC is resulting in the code ending up in the IntDefaultHandler.  I presume it's some sort of issue with my U1RX_ISR not linking up properly?  but in that case, how would I go about configuring this interrupt?  Would it be better practice to increase the buffer size and use the internal interrupt?

In the code, I am first calling

 CyGlobalIntEnable

then

U1RX_ISR_Enable()

and finally

UART1_Start();

This is my first time working with a PSoC, so I'm still unfamiliar with best practices and exactly how to configure interrupts properly.

Thanks in advance for the help.

Hey,

We have never used JTAG in production but are working on a new PCB which will have 3 PSoC's on it.  Two will have the same code and one will have different code. 

I see that the MiniProg3 supports JTAG.  If we daisy chain JTAG to the 3 devices, will it support programming them (2 with the same code and one with different code)?  Does the PSoC Programmer support this?  Can it be automated to do all 3 with one command?

Thanks,

Mike.
