 Hi,I built a project with 3 components: ADC,a verilog based component, VDAC. The verilog component is used to do some digital processing work. Here is the question:  how can I put the ADC's result to my  verilog component,Ican't find the component's base address or data bus connect interface,how can I put the verilog based component into my system and use it. Thank you for reply.

Hi all

I want to use multi DMAs by parallel rather than using first DMA to request next DMA. For example,  I use a custom trigger component  to request DMAs one by one. I assume that each DMA component can work individually and run as parallel, so that total DMA speed can be accelerated.  It is just what I expect and assume, could any one tell me this is available or not??   Or there is an another way which can speed up DMA.

Thanks

Hi,

I use USBFS w/ Automatic DMA, ISOC EP and max packet size of 512Bytes.

When i execute only once the command:

USBFS_LoadInEP(EP1, USBFS_NULL, sizeof(EP1_RAM));

I see that the data in the EP is pending even after i read it in the C# application (i use the AN56377 example).

how can i make the burst of 512bytes to send only once and not endlessly?

Thank you,

Naftali.

Hello

I'm seeing the example of delsig_I2CM01 in psoc creator, but i don't understand this lines:

        sample_segment[0] = sample_full >> 8u & 0x00FFu;
        sample_segment[1] = sample_full & 0x00FFu;

someone could explain to me these lines

Thanks for your help

Hi every one !

I would need help using malloc() library function.

I would need to create a fuction in C  that take an Array like argument , procces that array  and return a pointer to an array which is the product of the function's procces.

I have tried using  function like   uint8 *Function_X ( uint8 &Arg_ Array[ ] );  like declaration and.....

something like this as definition;

  uint8 * Function_X( uint8 & Arg_Array[0 ] ) {

 satic uint8 Array_1[[16];

                              fuction body

                           return (array_1);

}

The caller function  is something like this:

In the file that call  " uint8  * Function_X ( uint8 & ASrg_Array[ ] )  " ,   I declare a pointer let say  "uint8 Ptr."

When I call the function is something like this assuming that I want to process  uint8 Payload [16]:

   Ptr= Funtion_X ( & Payload[0] );

Afterward I espect transfer the product of the process through the pointer Ptr, but I can't find the 16 element of the processed array . 

That's why  I am trying to use other method  like malloc.

But the keil compiller declare like mandatory to call  init mempool previously  and up to this point reach my knowledge.

Can someone else help me with that ?

Thank all of you for your time for help me

Hi,

How  much is the resistance of the internall pull-up of a PSoC5LP?.

Currently I have a PSoC5LP connected to 20 SPI Slave devices with 20 separate chip select lines (digital output, resistive pull up).

Since the pins are connected to Vdd, I would like to know how nuch is the current draws, and if I need an external pullup resistor
