PSoC™ 5, 3 & 1 Forum Discussions

Hello,

  I have been following the EP56061 tutorial guide in trying to get the PSoC 5 (CY8CKIT_014) to communicate with UART HyperTerminal. I had followed the exact instruction of the guide and used the PmodRS232 (RS232 converter) connected to the RS232 port and wired it directly to J2 & J3 header. Unfortuately, I am not able to see the result through the Hyperterminal and I would like to know what is it that I am missing because I have all the specs and configurations correct. Please help! Thanks!

Hello Sir,

I am using Psoc 3  with CY8CKIT-001. I am using Psoc creator 1 for programming

I want to receive serial data at 9600 baud rate from UART.

I got help from sample code of 8 bit Uart from cypress site.

But that project does not get open directly. So I read all its C file and than made my own project which builds completely .

But still no output is seen on hardware.

Points:  

1) I have checked jumper 10 is properly placed.

2) I have made top design as per pdf  EP56061_Archive.

3) My main c file is same as that in EP56061_Archive.

4)My ISR_UART c file is same as that in EP56061_Archive.

*******************************************************************************

* File Name: ISR_UART_intc.c  

#include <UART.h>

extern uint8 flag_keyPress;

CY_ISR(ISR_UART_Interrupt)

{

    UART_GetRxInterruptSource();    

/* To indicate key press */

flag_keyPress = 1; 

}

Please reply fast because I have stucked at this point from last 8 days

Is it possible to implement the CORDIC sin or cos function in a UDB? I would think that using the internal datapath in the UDB would allow for a serial CORDIC algorithm to be made.

Is this feasible?

I need to implement an EZ-I2C EEPROM emulator which can hold about 4kB of read-only data. This is obviously far too much to hold in RAM, but would easily fit in FLASH. This is for a CY8C3666LTI-079

However, the EZ-I2C API only lets me pass a void* pointer (which I assume can only point to RAM).

Is there some way I can make it take data from a FLASH array?  Or could the component easily be modified to enable this?

 how can i RESET the PSoC kit to to the state in which I received the kit....?????????

i am using "CY8CKIT _001" PSoC development kit......

 Hello, could somebody help me in how to configure one DMA block (specially number of bytes per burst, and number of request per burst) to do this?:

I have one DFB outputting 16bit words at Fs (3KSPS)

Its EOC fires one DMA request ina DMA block

I want the DMA to transfer first Low byte (available in HOLDA_PTR) then HIgh byte (in HOLDAM_PTR) to one UART (UART_1_TXDATA_PTR)

I have tryied several configs, using one or two transfer descriptors, but I only get one byte out off the UART for every EOC.

See my last attempt (only sends out one byte):

uint8 DMA_3_Chan;

uint8 DMA_3_TD[1];

#define DMA_3_BYTES_PER_BURST 2

#define DMA_3_REQUEST_PER_BURST 1

#define DMA_3_SRC_BASE (CYDEV_PERIPH_BASE)

#define DMA_3_DST_BASE (CYDEV_SRAM_BASE)

/* DMA Configuration for DMA_3 */

DMA_3_Chan = DMA_3_DmaInitialize(DMA_3_BYTES_PER_BURST,DMA_3_REQUEST_PER_BURST,

                                                                                HI16(DMA_3_SRC_BASE),HI16(DMA_3_DST_BASE));

DMA_3_TD[0] = CyDmaTdAllocate();

CyDmaTdSetConfiguration(DMA_3_TD[0], 1,  DMA_INVALID_TD, TD_INC_SRC_ADR);

CyDmaTdSetAddress(DMA_3_TD[0], LO16((uint32)Filter_1_HOLDA_PTR), LO16((uint32)UART_1_TXDATA_PTR));

CyDmaChSetInitialTd(DMA_3_Chan, DMA_3_TD[0]);

CyDmaChEnable(DMA_3_Chan, 1);

Thanks,

 when i am debugging a project  the tool is showing this ERROR"" 'Failed to send JTAG packet (jtagio)' received while attempting to read memory 0x00000000-0x00000002"""

what should i do to avoid this?????

also please give replies for the previous POSTS which i have sent to U.......
